EXECUTIVE SUMMARY
ENVIRONMENTAL RADIATION SURVEILLANCE IN GEORGIA: 2000 2002
Georgia recognizes that nuclear facilities may affect environmental radiation levels by the introduction of man-made radioactive materials into the environment. In 1976 the Georgia General Assembly amended the Georgia Radiation Control Act, O.C.G.A. 31-13, to charge the Environmental Protection Division (EPD) of the Georgia Department of Natural Resources with responsibility for monitoring of radiation and radioactive materials in the environment. The Environmental Radiation Program in EPD measures and determines if radioactive materials are being released into the environment in quantities sufficient to adversely affect the health and safety of the citizens of Georgia. This report provides results from the environmental radiation monitoring performed by the Environmental Radiation Program during calendar years 2000, 2001 and 2002. Since 1976, EPD has operated extensive radiation monitoring networks at nine facilities in or bordering Georgia. These facilities are:
(1) U.S. Department of Energy, Savannah River Site (Jackson, South Carolina); (2) Georgia Power Company, Vogtle Electric Generating Plant (Waynesboro, Burke Co.); (3) Georgia Power Company, Edwin I. Hatch Nuclear Plant (Baxley, Appling Co.); (4) Alabama Power Company, Joseph M. Farley Nuclear Plant (Dothan, Alabama); (5) U.S. Navy, Naval Submarine Base, Kings Bay (St. Marys, Camden Co.); (6) Georgia Tech Research Reactor Now Decommissioned (Atlanta, Fulton Co.); (7) Dawson Forest Wildlife Management Area (Dawsonville, Dawson Co.); (8) Tennessee Valley Authority, Sequoyah Nuclear Plant (Chattanooga, Tennessee); (9) Duke Power Company, Oconee Nuclear Plant (Seneca, South Carolina).
Georgia's environmental radiation monitoring networks cover more than 3000 square miles of land area and more than 300 miles of waterways in Georgia. Environmental samples are analyzed for radioactive materials at the Environmental Radiation Laboratory at Georgia Tech. EPD's Environmental Radiation Program associates, operating from Atlanta and the EPD East Central District Office in Augusta, regularly perform both instantaneous and time-averaged direct radiation measurements and collect samples of environmental media including air, surface water, groundwater, rain, stream sediment, fish, soil, vegetation, milk, game animals and crops near these facilities and at background locations around the state. Sample collection methods and laboratory analysis protocols are discussed in greater detail in Sections B and C of this report.
The vast majority of results from EPD environmental monitoring indicate that radiation levels and concentrations of man-made radionuclides remained consistent with background radiation levels. However, several areas or categories that were tested had elevated concentrations of manmade radionuclides or elevated radiation levels attributable to operations at the facility monitored, as depicted on the front cover of this report. Of these locations or categories, none regularly exceeded U.S. Nuclear Regulatory Commission reporting levels. However, five (5) exceptions were noted during the period covered by this report:
Georgia Environmental Radiation Surveillance Report 2000 2002 Executive Summary Section A A-1

Reporting-Level Exceptions:
(1) Panfish in the Beaver Dam Creek area of the Savannah River, adjacent to the Savannah River Site, exceeded the aquatic pathway reporting level of 10 mrem/yr to bone: 122% of the reporting level with a projected dose of 12.2 mrem/yr to bone.
(2) Catfish from the Beaver Dam Creek area of the Savannah River, adjacent to the Savannah River Site, exceeded the reporting level of 10 millirem (mrem) per year (mrem/yr) to bone: 236 % of the reporting level with a projected dose of 23.6 mrem.
(3) Catfish from the Four Mile Creek area of the Savannah River, adjacent to the Savannah River Site, exceeded the aquatic pathway reporting level of 10 mrem/yr to bone: 245 % of the reporting level with a projected dose of 24.5 mrem.
(4) Leafy vegetation (forage) from two locations in southern Richmond County exceeded the airborne-pathway reporting level of 15 mrem/yr to bone: 370 % of the reporting level with a projected dose of 56 mrem at Bush Field; 170% of the reporting level with a projected dose of 26 mrem at McBean.
(5) Direct radiation, along the south and west fence-lines of the Georgia Tech Research Reactor, exceeded the reporting level (with doses up to 81 mRem in a year during D&D) but not the annual dose-limit (100 mRem).
The reporting level is used as a guideline by the Nuclear Regulatory Commission to monitor or to flag the impact of a facility. It is equivalent to a committed effective dose of 10 mrem per year (or 15 mrem per year to any critical organs of the body) for the air-pathway, which includes inhalation and any associated fallout-related doses from ground-shine and from consumption of food products. The reporting level for the aquatic pathway is lower: equivalent 3 mRem committed effective and 10 mrem to any organ, including doses from drinking water, consumption of fish and seafood, swimming, and ground-shine along river banks. By comparison, the National Council of Radiation Protection estimates the average U.S. citizen receives around 40 mrem per year from medical X-rays and 10 mrem per year from consumer products such as tobacco, smoke detectors, and luminous dials and signs. In comparison with normal statewide exposure to background radiation in the environment, which averaged 65 mrem per year for 2000-2002, the potential impact from eating fish is not significant. The estimated lifetime risk due to eating the edible portions of fish taken from the Savannah River is extremely small (on the order of 4 in a million, on the average).

Air

Tritium (H-3)

Rain / Fallout Tritium (H-3)

Elevated levels of tritium (> 5X Bkg) were periodically detected at 8 out of 10 locations within 30 miles of SRS, with highest concentrations detected within SRS' predominant down-wind footprint. H-3 concentrations ranged from 2000 - 24,000 fCi/m3. All results were equivalent to less than 0.01 mrem per year or 0.1 % of the air-pathway reporting level (15 mrem/yr), and therefore, did not pose a significant risk. Based on periodic effluent reports, SRS is assumed to be the primary source of airborne H-3 (99.8%), with Vogtle contributing approximately 0.2%.
Elevated levels of tritium (up to 5X Bkg) were observed in precipitation at several locations within 30 miles of SRS, with highest concentrations within SRS's predominant down-wind footprint. Detectable deposition (fallout) values for H-3 ranged from 4,000 pCi/m2 to 92,000 pCi/m2 per year. Even though a significant amount of H-3 was deposited in the rain, H-3 concentrations in the rainwater did not exceed the Safe Drinking Water Standard: 400 pCi/L average (2% MCL) and 1,000 pCi/L maximum (5% MCL). Thus, the H-3 did not pose a significant risk.

Milk

Tritium (H-3) Slightly elevated levels of tritium (up to 3X Bkg) were

detected in milk from 2 locations within 50 miles of SRS.

Detectable H-3 values ranged from 200 to 700 pCi/l., with

average results less than 0.05 % of the air-pathway

reporting level (15 mrem/yr).

Crops: Pears

Tritium (H-3)

Groundwater Tritium (H-3)

Slightly elevated levels of H-3 (2X Bkg) were detected in pears from the Waynesboro area, about 25 miles from the center of SRS. H-3 concentrations were below any level of concern, with a projected dose less than 0.002 mrem per year (<0.02% of the reporting level).
Elevated concentrations of tritium (up to 5X Bkg) were detected in relatively shallow (< 100') groundwater within 15 miles of the center of SRS. Concentrations were not significant (equivalent to 5% of the Drinking Water MCL). All of the elevated readings are within the predominant down-wind footprint of SRS, where elevated H-3 fallout in rain was also detected. H-3 fallout from SRS is primary mechanism suspected for the contamination, but other potential pathways, such as underground migration, are still under investigation by USGS.

Leafy Vegetation (Forage)

Tritium (H-3)

Elevated levels of tritium (up to 13X Bkg) were detected in leafy vegetation or forage from several locations within 50 miles of SRS. Detectable H-3 concentrations averaged approximately 500 pCi/kg of fresh weight, with a maximum of 2,600 pCi/kg. H-3 concentrations averaged less than 0.02% of the air-pathway reporting level. Highest H-3 concentrations were observed within SRS's predominant downwind footprint.

" " Deer

Sr-90 (Exceeds Reporting Level)
Tritium (H-3)

Elevated Sr-90 (up to 4X Bkg) concentrations were detected in leafy-vegetation (forage) samples southeast of Augusta near Bush Field and McBean (~ 20 miles from the center of SRS). SRS estimates off-site population doses of approximately 66,000 person-mRem from SRS-related strontium fallout in vegetation (WSRC-TR-970152- Sr-89/90 p4), so some of this Sr-90 may be SRS-related. Since Sr90 is also present in global fallout, as well as SRS fallout, it is difficult to positively distinguish the two, however. Leafy vegetation from both locations in southeastern Richmond County exceeded the air-pathway reporting level of 15 mrem/yr (370% near Bush Field and 170% near McBean).
Slightly elevated levels of H-3 (3X Bkg) were detected in deer samples collected near the Savannah River (within 5 miles of SRS). H-3 concentrations were below any level of concern, with a projected dose less than 0.002 mrem per year (~0.01% or the air-pathway reporting level).

Cs-137

Elevated concentrations of Cs-137 (up to 4X Bkg) were detected in deer samples collected within 2-5 miles of SRS. Since Cs-137 is known to be present both in global fallout as well as in SRS effluents, it is difficult to distinguish which source (SRS or global fallout) is the primary contributor in this situation. Further study will be necessary to positively determine the source.

Dose

The projected 2002 deer-consumption dose (near SRS) to an average offsite-hunter in Georgia, averaged 3.5 mrem (or 22% of the reporting level), due primarily to Cs-137. This compares favorably with recent SRS offsite-hunter dose estimates (2.9 mrem adjusted to average consumption - WSRC-TR-2000-00328, p.121). SRS assumes that deer migration from the Site is the primary mechanism contributing to offsite doses from SRS.

Cancer Risk

Preliminary 30-year cancer-morbidity risk estimates near SRS averaged 7.8E-05 or 78 out of 1,000,000 for consumption of deer meat. Several years' worth of data are needed to provide a more accurate risk assessment, however, since the current risk assessment is based only on a single year (2002).

Soil

Pu-239

One soil sample taken in the Shell Bluff area adjacent to

SRS had a higher percentage of Pu-239 (per unit of Cs-

137) than all of the other samples tested (15% higher),

suggesting that the excess Pu-239 may be from SRS. Shell

Bluff is located within SRS's predominant down-wind

footprint, approximately 10 miles from plutonium-processing

facilities, where much higher Pu-239/Cs-137 percentages

have been detected in soil (WSRC-RP-92-879-Rev-1).

River Water Effluent (Outfalls)

Tritium (H-3) General Information

Since Cs-137 and Pu-239 are known to be present, both in global fallout as well as in SRS effluents, it is difficult to positively distinguish which source (SRS or global fallout) contributed the excess Pu-239. More study will be necessary to determine whether the excess Pu-239 near Shell Bluff is SRS-related. (SRS estimates a population dose of 121,000 person-mrem, through 1995, due to SRSrelated fallout of Pu-239 onto vegetation ... WSRC-TR970152, Pu-239-p.4). Elevated concentrations of tritium (up to 300X Bkg) were detected in river water adjacent to SRS effluent creeks (outfalls), with concentrations ranging up to 60,000 pCi/l (equivalent to 300% of the MCL for a one-week period at Four-Mile Creek). Annual average concentrations were less than the Safe Drinking Water MCL, however, at all locations monitored. Uptake of H-3 from river water near these outfalls is mainly expected to be mainly from fish consumption rather than from drinking water.

I-129

Elevated I-129 (up to 6X Bkg) in river water was detected at one SRS outfall (Four-Mile Creek). Concentrations ranged from 0.2 pCi/l to 0.7 pCi/l, averaging 0.4 pCi/l, which is equivalent to 40% of the MCL or reporting level, based on use as a drinking water supply (unlikely). Instead, most uptake of I-129 from this outfall is expected to be through consumption of nearby aquatic plants, fish, or deer.

Cs-137

Elevated tritium (up to 50X Bkg) in river water was detected below the Vogtle outfall. H-3 concentrations averaged 2,200 pCi/l (11% of MCL), with the highest concentration (11,000 pCi/l) associated with a chemistry problem in one of the reactors. This required a temporary shutdown and system cleanup near the end of 2002. Elevated tritium (up to 16X Bkg) was detected in river water downstream of SRS and VEGP at the US-301 Bridge. H-3 concentrations averaged 1000 pCi/l (5% MCL), with a maximum of 3,300 pCi/l (16% MCL). Approximately 90% of the H-3 is from SRS, with around 10% from Vogtle, based on available effluent reports. H-3 did not pose a significant risk based on measured concentrations. Elevated concentrations of tritium (up to 11X Bkg) were detected in downstream drinking water from the Savannah I&D Water Plant. Concentrations averaged 800 pCi/l (4% MCL), with a maximum of 2,300 pCi/l (11% MCL). As noted above, most (~ 90%) of this H-3 is from SRS. H-3 did not pose a significant risk based on measured concentrations. Elevated concentrations of Cs-137 in sediment (up to 540X Bkg) were detected adjacent to and up to 100 miles downstream of SRS. Based on isotopic-ratios' analysis of the data, over 80% of the Cs-137 in Savannah River sediment is probably Site-related. Elevated Cs-137 in sediment (from SRS creeks) is responsible for most of the Cs-137-problem found in fish from this area, and, therefore potentially poses a long-term risk to the human population.

Elevated Cs-137 (approximately 2X Bkg) was detected at Vogtle one time, but the average concentration was statistically indistinguishable from the control concentration.

Co-60

Elevated concentrations of Co-60 in sediment were measured at SRS - Steel Creek (up to 14X Bkg) and below Plant Vogtle (up to 15X Bkg), suggesting that Co-60 originated from both SRS and Vogtle. Co-60 was also detected up to 100 miles downstream (up to 22X Bkg). Co60 was not detected in drinking water or fish samples, indicating negligible impact to human populations.

Pu-238 and Pu-239

Elevated Pu-238 (up to 3X Bkg) and Pu-239 (up to 6X Bkg) were detected in sediment samples adjacent to and up-to 100 miles downstream of SRS. Based on isotopic-ratios' analysis, up to 80% of the plutonium detected appears to be Site-related and probably entered the Savannah River from Four-Mile Creek (SRS). Global fallout-related Pu-239, not related to SRS, was also detected at a saltwater control location in the Richmond Hill / Savannah area on the Ogeechee River. Neither Pu-238 nor Pu-239 were detected in drinking water or fish samples, indicating negligible impact to human populations.

Current DNR fish consumption advice, which recommends

limiting consumption of largemouth from this area to one

meal per week, based on mercury, is sufficient to cover

radiological risk, as well. Downstream risk levels, measured

in fish between US301 and Savannah, were essentially the

same as background, which was measured upstream near

Augusta, indicating that the radiological problem area is

H-3 and Cs-137
Tritium (H-3)

Elevated concentrations of Cs-137 and H-3 were also detected in fish samples near Plant Vogtle, which is located adjacent to SRS and Four-Mile Creek. The majority of Cs137 activity detected in Vogtle fish is likely to be SRSrelated, based on the upstream control samples. Vogtlerelated activity was equivalent to less than 3% of the aquatic-pathway reporting level. The 30-year radiological cancer morbidity risk for fish consumed from this area was estimated to be between 1 and 2 out-of 1,000,000.
Elevated tritium (up to 23X Bkg) in Chattahoochee River water was detected approximately 3 miles downstream of Farley in three-out-of-twelve grab water samples. All other samples were non-detectable for H-3. The average detected concentration (1,100 pCi/l) was equivalent to less than 6% of the Drinking Water MCL.

Plant Farley River Sediment

Co-60

Slightly elevated concentrations (up to 2X Bkg) of Co-60 (attributed to Site operations) were detected in sediment samples approximately 3 miles downstream of Plant Farley. Activity levels were insignificant and did not pose a detectable risk for drinking water or fish.

Plant Hatch River Sediment

Mn-54, Co-60

Slightly elevated concentrations (up to 6X Bkg) of Mn-54 and Co-60 (attributed to Site operations) were detected in the Altamaha River up to 50 miles downstream of Plant Hatch. Neither of these radionuclides was detected in water or fish samples, and thus, did not result in a measurable risk to the human population.

Elevated Cs-137 was also detected in sediment approximately 90 miles downstream in the coastal area, but the concentrations were comparable to Cs-137 at the coastal-control location (Ogeechee River). Given the comparability of results from both coastal locations and given the absence of Co-60 at the Plant Hatch coastal location, the Cs-137 was attributed to global fallout. Slightly elevated concentrations (up to 2X Bkg) of H-3 were detected in Lake Hartwell near the Hartwell Dam. Detectable H-3 averaged 250 pCi/l (less than 2% of MCL).

Direct Radiation

Detectable concentrations of Co-60 (up to 11X Bkg) and Eu-152 (up to 26X Bkg) were measured in soil next to the decommissioned Georgia Nuclear Aircraft Laboratory (GNAL) reactor site at Dawson Forest Wildlife Management Area. Co-60 and Eu-152 are neutron activation products that were created in soil when the reactor was operating (outdoor operation).
This activity has been previously documented as having no measurable or significant impact to other environmental pathways, except for minimal direct exposure. Direct radiation from this activity, which was measured via in-situ gamma spectroscopy, was found to be acceptable: less than 10 mrem per year for continuous exposure. Georgia Tech Research Reactor (GTRR) was demolished and decommissioned (D&D) during the 2000-2002 period. This involved the cutting and removing of a number of activated reactor components, including the reactor vessel, graphite, concrete, and lead shield, which were subsequently shipped offsite for disposal as radioactive waste. During this period, external gamma radiation levels were slightly elevated at the fence-line, due to gammashine from inside of GTRR and from radioactive-waste shipments. A network of monthly-serviced TLDs (ThermoLuminescent Dosimeters) was deployed around the perimeter fence-line, prior to D&D, to provide a highresolution, sensitive monitoring capability. This supplemented an existing quarterly TLD network.
Elevated direct radiation dose-rates (up to 4X Bkg or 275 mRem/yr above background) were detected at the fenceline on several monthly-TLDs, which surrounded GTRR. Although the reporting level was exceeded along the west and south fence-lines, the highest annual off-site dose (81 mrem) measured at the west fence-line, did not exceed the 10CFR20.1301-1302 annual dose limit (100 mrem). Gamma radiation was also detected and monitored in realtime with a remotely controlled gamma-radiation detector. Dose rates up to 4X Bkg were also detected during D&D by this instrument.

Slightly elevated concentrations (up to 10X Bkg) of H-3 were briefly detected in several air samples during D&D operations, after pipe cutting and removal operations, and during removal of the reactor vessel. The calculated dose for measured airborne H-3 was 0.002 mrem (or less than 0.02% of the air-pathway reporting level). Slightly elevated concentrations (up to 2X Bkg) of H-3 in surface run-off water were also periodically detected during the same pipe-cutting operations noted above. Results averaged 300 pCi/l (2% of the Drinking Water MCL).

Georgia Tech Vegetation H-3 Research Reactor (GTRR)

Slightly elevated concentrations (up to 3X Bkg) of H-3 in vegetation samples were also detected during the same pipe-cutting operations noted above. Results averaged less than 2% of MCL, based on the H-3 content of the vegetation moisture.

Vegetation Co-60 And Soil
Georgia Tech Waste Water H-3 Research Reactor

Slightly elevated concentrations of Co-60 were also detected in one vegetation sample (9X Bkg), and in one soil (4X Bkg) soil sample, separated by a five-month interval, starting during graphite-removal phase. It was assumed that the Co-60 had been deposited as a result of a very localized release, either as an airborne release or as a surface run-off water release. Assuming an airborne release, the dose was estimated to have been no more than 0.01 mrem (effective) and 0.07 mrem (lungs), which would have been equivalent to no more than 0.5% of the air-pathway reporting level.
Elevated concentrations of H-3 were measured in wastewater samples during the pipe-cutting operations. All measured concentrations were less than the maximum permissible concentration (MPC) limit for liquid effluent.

A detailed discussion of the findings related to each of the monitored nuclear facilities may be found in Sections D-K of this report. The following is a brief summary of the major findings for each facility.

Savannah River Site (SRS) / Vogtle Electric Generating Plant

Georgia DNR's most extensive environmental radiation monitoring network is focused on an area in Georgia adjacent to and downstream of the U.S. Department of Energy's Savannah River Site (SRS) in South Carolina and Georgia Power Company's Vogtle Electric Generating Plant (VEGP) in Georgia. A commercial radioactive waste burial ground facility, operated by ChemNuclear, is also located near the monitored area (adjacent to SRS and Lower Three Runs Creek). Because of the relatively close proximity of the Savannah River Site to the Vogtle Electric Generating Plant, a single combined monitoring network has been utilized by DNR since approximately 1978.

Georgia Power Company's Vogtle Electric Generating Plant (VEGP) is a two-unit Pressurized Water Reactor (PWR) facility located on a 5-square-mile tract of land adjacent to the Savannah River in Burke County, Georgia approximately 20 miles southeast of Augusta. This facility, which was supplied by the Westinghouse Corporation, and which is operated by Southern Nuclear Operating Company, has been in operation since 1985.
The U.S. Department of Energy's Savannah River Site (SRS) is a large, U.S. Government complex that has been operated since the early 1950's, primarily for the production of special nuclear materials, including tritium (H-3) and plutonium, used in nuclear weapons. SRS also provides nuclear materials for other purposes, such as plutonium-238 (Pu-238) for radioisotope thermal generators and radioisotope heaters in support of NASA interplanetary space missions. The SRS area includes numerous airborne emission points distributed over a 300-square-mile area, as well as numerous waterborne emission points, which feed into a 30-mile stretch of the Savannah River. Westinghouse Savannah River Company (WSRC) currently operates SRS under contract to DOE. Facilities at SRS include five (5) mothballed reactors, two (2) large radiochemical separations plants, a large high-level waste processing plant, a radioactive-waste incinerator plant, two (2) high-level-radioactive-waste tank farms, several radioactive waste burial grounds, fuel & target plants, etc. Many of these facilities are being actively decommissioned.
Although the reactors at SRS are no longer operating, millions of gallons of highly radioactive liquid waste and thousands of spent fuel elements still pose a significant, long-term environmental risk, requiring continued monitoring. Future missions at SRS, including the disassembly and reprocessing of plutonium pits and the recovery and recycling of excess plutonium and uranium for mixed-oxide (MOX) commercial reactor fuel, will also require continued vigilance for many years, due to the long-lived nature of the processed material. SRS also is the nation's sole site for the tritium recycle mission, in which tritium is removed from weapons reservoirs, purified, and then loaded back into reservoirs for reuse. SRS is also slated to be the site for recovery of tritium produced in commercial nuclear reactors.

During the period that DNR has monitored SRS, several site-related radionuclides have been detected periodically by DNR, including tritium (H-3), cobalt-60 (Co-60), strontium-90 (Sr-90),

iodine-129 (I-129), cesium-134 (Cs-134), cesium-137 (Cs-137), plutonium-238 (Pu-238), and plutonium-239 (Pu-239). During the current (2000-2002) period, all of the above SRS-related radionuclides (except for Cs-134) were detected:

1) H-3 was detected in many samples from a 400 square-mile area of land in Georgia adjacent to SRS, including air (up to 5x background), rain (up to 5x background), groundwater (up to 5x background), vegetation (up to 13x background), and crop samples. Airborne emissions from SRS are believed to be responsible for the majority of these results.
2) H-3 was also detected in river water samples over a 130-mile stretch of the Savannah River and its tributaries (up to 240x background adjacent to SRS and up to 16x background downstream of SRS). H-3 was also detected in fish samples over the same area of the river (up to 230x background near SRS and up to 9x background downstream of SRS).
3) Long-lived I-129 was detected in water from Four-Mile Creek, a tributary of the Savannah River. This radionuclide, which is attributed to SRS, is attributed primarily to seepage from closed radioactive-waste treatment basins and burial grounds located at SRS.
4) Elevated Co-60 (up to 22x background), Sr-90, (up to 3x background), Cs-137 (up to 540x background), Pu-238 (up to 3x background or MDC) and Pu-239 (up to 6x background or MDC) were detected in sediment samples adjacent to and up to 100 miles downstream of SRS. Based on observed isotopic ratios, it appears that discharges from SRS may be responsible for at least 80% of the Cs-137 and up to 50% of the Pu-238 and Pu-239 in the Savannah River downstream of SRS. A portion of the off-site Co-60 is may be attributed to VEGP as well as to SRS.
5) Cs-137 and Pu-239 were detected in several soil samples. Most of the activity in these samples appears to be related to global fallout, with the possible exception of a sample from Shell Bluff Landing, which is in the most predominant downwind direction from SRS.
6) Elevated Sr-90 (up to 5x background) and Cs-137 (up to 220x background) were detected in fish samples adjacent to the SRS area.
7) Elevated Cs-137 (up to 4x background) and H-3 (up to 3x background) were detected in deer samples collected in Georgia adjacent to SRS.
8) Somewhat elevated Sr-90 (up to 4x background) was detected in vegetation samples from two locations northwest of SRS near Augusta.

During the period that DNR has monitored Plant Vogtle (VEGP), three Site-related radionuclides have periodically been detected in the aquatic environment, including H-3 in river water, Co-58 in river sediment, and Co-60 in river sediment. During the current 2000-2002 period, H-3 and Co-60 were the only man-made radionuclides detected that may be attributed to Site operations:
1) H-3 was detected in river water (up to 50x background) downstream of Vogtle in one sample after a chemistry problem in one reactor (near the end of 2002), which required system shutdown and cleanup.
2) Co-60 was detected in river sediment (up to 7x background) downstream of Vogtle.

Edwin I. Hatch Nuclear Plant

Georgia Power Company's Plant Edwin I. Hatch is a two-unit Boiling Water Reactor (BWR) facility located on the Altamaha River in Appling County, Georgia, adjacent to Toombs County.

Georgia Environmental Radiation Surveillance Report 2000 2002 Executive Summary Section A

A-12

This facility, which was supplied by the General Electric Company and which is operated by Southern Nuclear Operating Company, has been in operation since 1975.
The Georgia Department of Natural Resources has monitored Plant Hatch since 1978, during which period site-related radionuclides were generally non-detectable in most off-site samples, with the exception of downstream river sediment. Site-related, low-level Co-60 and Mn-54 have been routinely detected in sediment. Site-related Cs-134 and Cs-137 were also detected in sediment following a 1986 spill of water from the spent fuel pool. Global fallout-related radionuclides (Nb-95, Zr-95, Ru-103, Ru-106, Ce-141, Ce-144, and Cs-137) were also detected one year (1981) during the Chinese weapons testing period. Chernobyl-related fallout radionuclides (I-131, Cs-134, Cs-137, Ru-103, and Ru-106) were detected another year (1986).
During 2000-2002, Co-60 and Mn-54 in river sediment (up to 6x background) were the only siterelated radionuclides detected above background levels.
Joseph M. Farley Nuclear Plant
Alabama Power Company Plant Joseph M. Farley is a two-unit Pressurized Water Reactor (PWR) facility located on the Chathoochee River in Houston County, Alabama, adjacent to Early County, Georgia. This facility, which was supplied by the Westinghouse Corporation, and which is operated by Southern Nuclear Operating Company, has been in operation since 1977.
The Georgia Department of Natural Resources (DNR) has monitored Plant Farley since approximately 1978. Historically, low levels of Co-60 in river sediment and low level of tritium (H-3) in river water are the only site-related radionuclides detected. However, several global fallout-related radionuclides (including Nb-95, Zr-95, Ru-103, Ru-106, Ce-141, Ce-144, and Cs137) were also detected one year (1981) during the Chinese weapons testing period. Cs-137 is the only one of these nuclides that is still detectable.
During the current 2000-2002 period, H-3 in river water (up to 23x background) and Co-60 in river sediment (up to 2x background) were the only site-related radionuclides detected.
Naval Submarine Base, Kings Bay
Naval Submarine Base, Kings Bay supports the Trident Nuclear Submarines and their associated ballistic missile systems, as a part of the U.S. Navy's Fleet Ballistic Missile Submarine facilities. Kings Bay also supports other classes of submarines. It is situated between St. Mary's, Georgia on the west and Cumberland Sound on the east, in Camden County. Submarine wharves, drydocks, and other support facilities are located on the waterfronts of Kings Bay and Cumberland Sound.
The Georgia Department of Natural Resources (DNR) has monitored Kings Bay since it began operations in 1978. During this period, no measurable radioactivity that could be attributed to operations at the facility has been detected by DNR. Only naturally occurring radionuclides and global fall-out-related Cs-137 have been detected in the environment around King's Bay.

Georgia Tech Research Reactor (decommissioned)
The decommissioned Georgia Tech Research Reactor (GTRR), located at the Frank H. Neely Nuclear Research Center on the Georgia Tech Campus in Atlanta, Georgia, was a 5-megawatt, highly enriched, heavy water moderated research reactor. Prior to the 1996 Olympics, it was permanently shut down and de-fueled in preparation for its decommissioning, which is now complete (Figure A-1). DNR has monitored GTRR since 1978, when it was first given that responsibility. Historically, the only routinely detectable radionuclides that could be attributed to GTRR operations were H-3, Co-60, Cs-137, and gross beta in liquid effluents. Once sampled and determined to be within regulatory limits, liquid effluents were discharged to the sanitary sewer. Global fallout-related radionuclides (including Nb-95, Zr-95, and Cs-137) were also historically detected, with fresh deposits detected during 1981 after a series of Chinese weapons tests. Of these radionuclides, Cs-137 is the only global fallout-related radionuclide still detectable

Figure A-1: Top View: Georgia Tech Research Reactor Before, During, and After It's Removal.
Bottom View: Truck Hauling GTRR Reactor Vessel Away in a Shielded Cask for Burial.

During the current 2000-2002 period, which involved demolition and decommissioning (D&D) of GTRR, elevated direct gamma radiation and slightly-elevated levels of radionuclides (H-3 and Co-60, at levels up to 10x background) were periodically detected off-site (near the fence-line). Measurable direct radiation and environmental radioactivity from D&D appeared to have been confined to the immediate area (within approximately 100 feet) of the facility boundary, with no offsite impact in excess of regulatory limits. Although reporting levels were exceeded along the south and west fence-lines, offsite doses from all monitored pathways (which approached 81 mrem in a one year period between April-2000 and April-2001 at one location) did not exceed the annual dose limit (100 mrem) found in U.S. Nuclear Regulatory Commission regulations.

Dawson Forest Wildlife Management Area
Dawson Forest Wildlife Management Area (DFWMA) is a 10,000-acre tract of land located in Dawson County, approximately 5 miles southwest of Dawsonville, Georgia. It is the decommissioned site of the former Georgia Nuclear Aircraft Laboratory (GNAL), which was operated by Lockheed Aircraft Corporation, under contract for the U.S. Air Force, until it was decommissioned around the end of 1971. Facilities containing radioactive materials at GNAL included a test reactor, hot cell building seepage basins, and cooling-off area (for temporary outdoor storage of "hot" items after irradiation at the reactor site). The land, which is now owned by the City of Atlanta as a possible future airport site, is currently managed by the Georgia Forestry Commission for the purpose of forestry management and by the Georgia Department of Natural Resources for the purpose of game management.
DNR first initiated environmental monitoring of DFWMA shortly after their Environmental Radiation Program was formed at the end of 1977. At that time, a portion of the site was found to contain residual activity of possible concern, and two of these areas were fenced to prevent public access. Site structures, including the hot cell building, were also sealed to prevent access.
DNR has conducted quarterly or semi-annual direct (external) gamma radiation measurements in public-accessible locations at DFWMA for the past 25 years. A variety of instruments have been used for this task, including hand-held dose-rate monitors, a gamma spectrometer, and thermoluminescent dosimeters (TLDs). TLDs were the primary means used by DNR for continuous long-term dose monitoring. Gamma spectrometry was used primarily to determine the relative contribution of each radionuclide (including naturally occurring nuclides) to gamma doses. Hand-held instruments were used primarily to survey the perimeter to insure that hotspots remained confined.
Direct radiation dose rates, as recorded by the TLDs, have declined noticeably, during the past 25 years, in the restricted areas. Doses at all TLD locations currently appear to be nearing background levels. EPD environmental measurements have confirmed that the radioactive materials present on the site, primarily Co-60 and Eu-152 (up to 25x Bkg), are not mobile in the environment.
Sequoyah Nuclear Plant
Tennessee Valley Authority's Sequoyah Nuclear Plant is a two-unit Pressurized Water Reactor (PWR) facility located in Hamilton County, Tennessee approximately 20 miles northeast of Rossvile, Georgia. Westinghouse Electric Corporation supplied this facility, which has been in operation since 1980.
Several TLD and sample locations are included in DNR's network, with most of the monitoring focused on the northwest corner of Georgia, including Rock City, Rossville, Ringold, and Cohutta. DNR has monitored Plant Sequoyah since approximately 1980, with no detectable Siterelated activity. However, several man-made global-fallout-related radionuclides (including Nb95, Zr-95, Ru-103, Ru-106, Ce-141, Ce-144, and Cs-137) were detected many years ago (1981)

Georgia Environmental Radiation Surveillance Report 2000 2002 Executive Summary Section A

during the Chinese weapons testing period. Global fallout-related Cs-137 is the only man-made radionuclide that is still detectable. Oconee Nuclear Plant

Duke Power Company Oconee Nuclear Plant is a three-unit Pressurized Water Reactor (PWR) facility located adjacent to Lake Keowee, near Senaca, South Carolina, approximately 20 miles northeast of Toccoa, Georgia. It discharges into the headwaters of the Savannah River upstream of Lake Hartwell. Babcock and Wilcox Company supplied this facility, which has been in operation since 1974.
Several land and aquatic sample are included in DNR's network, which includes the northeast corner of Georgia, around and including Lake Hartwell. DNR has monitored Plant Oconee since approximately 1978, with no detectable site-related activity except for periodic low-level H-3 in surface water collected from Lake Hartwell (near the Hartwell Dam). However, several global fallout-related radionuclides (Nb-95, Zr-95, Ru-103, Ru-106, Ce-141, Ce-144, and Cs-137) were detected many years ago (1981) during the Chinese weapons testing period. Cs-137 is the only one of these fallout-related gamma-emitting radionuclides that is still detectable.

Radiological Emergency Response

By Executive Order of the Governor, the

Department of Natural Resources is the lead

state agency for response to and technical

assessment of peacetime radiological

incidents and emergencies. This

responsibility, assigned to the Environmental

Protection Division, is implemented by the

Environmental Radiation Program, with

assistance from the Radioactive Materials

Program. The Program also plays a major

role in radiological emergency planning and

preparedness efforts for the state, including

participation in radiological emergency exercises at Plant Hatch, Plant Vogtle, Plant Farley, and the Savannah River Site. Program associates are also involved in

Figure A-2. Florida, Georgia and DOE contractor staff consult on a field monitoring issue during the 2002 Joint Venture Exercise.

emergency preparedness and response activities related to the transportation of radioactive

materials.

The Federal Emergency Management Agency (FEMA) evaluates radiological emergency preparedness exercises at commercial nuclear power facilities. EPD participates in three evaluated radiological emergency preparedness exercises (Figure A-2) every two years. FEMA consistently has reported that the EPD emergency response capability for protecting the health and safety of Georgia's citizens in the event of a radiological incident as "adequate", and in many instances as "superior".

Georgia Environmental Radiation Surveillance Report 2000 2002 Executive Summary Section A

A-16

During 2000-2002, EPD participated in five

evaluated radiological emergency preparedness

exercises. In addition to these, in April 2002,

Georgia had the unprecedented opportunity to

participate in an exercise alongside the bulk of

the federal resources that, together, represent

the Federal Radiological Monitoring and

Assessment Center (FRMAC), the Advisory

Team for Environment, Food and Health (A-

Team), and the Aerial Measurement System

(AMS) all national radiological emergency

response assets. The Joint Venture ingestion pathway exercise (IPX) extended over 3 days,

health personnel from Alabama, Florida,

Georgia, North Carolina and South Carolina, as well as federal agency and contractor

participants. The exercise simulated a major release of radioactive materials affecting both

Georgia and South Carolina. Staff of both the EPD Environmental Radiation Program and the

Radioactive Materials Program were fully involved in the exercise, as were contract laboratory

personnel from Georgia Tech. Georgia, accompanied by Florida and North Carolina, deployed

its Mobile Radiological Laboratory (MRL) to co-locate with the FRMAC at the National Guard

Armory in Graniteville, SC (Figure A-3).

In addition to participation in periodic radiological emergency preparedness exercises, the Environmental Radiation Program, in conjunction with the Radioactive Materials Program, has responded to more than 80 incidents (roughly one every two weeks) involving radioactive materials during this report period. In one incident the Federal Bureau of Investigation requested identification of a mailed package that was radioactive. The FBI, fearing a radiological dispersion device, wanted EPD to characterize the package, which turned out to be a strong betaemitter (later determined to be Sr-90). EPD took possession of the package for later safe disposal. Other incidents (nearly 43%) involved contaminated scrap metal, including the buildup of naturally occurring radioactive materials (NORM) in manufacturing process equipment.

Although none of the incidents during this reporting period resulted in significant releases of radioactive materials to the environment, several incidents required decontamination of facilities and equipment. Contaminated scrap metal poses a special problem for EPD radiation specialists, in that the material involved needs to be quickly identified without undue risk to the investigator. In most cases, the source of radiation is NORM deposited on the surface equipment. However, during one response, EPD personnel determined the source of radiation to be a radioactive gage that had been improperly disposed.

EPD routinely uses a field-portable gamma spectrometer to help in the field identification of

radionuclides. Roughly a third of the incidents involved Georgia radioactive materials licensees or companies with radioactive materials licenses from the U.S. Nuclear Regulatory Commission

or other states doing business in Georgia under reciprocity. 11 incidents involved the detection of

radioactive materials, primarily short-lived medical radionuclides, at municipal or commercial landfills.

Section B - Environmental Radiation Program Activities
The Environmental Protection Division (EPD) of the Georgia Department of Natural Resources (DNR) conducts environmental radiation monitoring and emergency response activities related to nuclear facilities in and around Georgia. These activities are designed to protect the current generation and future generations of Georgia citizens from the harmful effects of chronic and acute releases of radioactive materials, including the transportation of radioactive materials. Assuring an adequate level of protection requires a robust program to monitor for radioactive materials in the environment and an equally robust radiological emergency response capability.
The primary emphasis for this program is the operation of an environmental monitoring program of sufficient depth and breadth to determine the extent to which radioactive materials are released into the air and water (both surface water and ground water) of Georgia. The program augments previous monitoring conducted by EPD, places additional emphasis on early detection and notification of releases of radioactive materials, and focuses on waterborne releases and pathways, and to a lesser extent on airborne and food-based pathways. During the past three years, EPD's ability to detect, quantify and assess the significance of both chronic and acute releases required increased sample collection and laboratory analysis efforts, including increases in the types and numbers of samples collected, more frequent sample collections, more comprehensive laboratory analyses of existing samples, and the performance of laboratory testing for additional radionuclides. A great deal of emphasis was placed on a buffer area approximately 1-5 miles wide along the Georgia side of the Savannah River from Augusta to Savannah.
The Georgia Environmental Radiation Program has benefited significantly by EPD's newly opened (2001) East Central District Office in Augusta. Two Environmental Specialists were hired and located in the Augusta office. The bulk of the environmental monitoring effort centered around the Savannah River Site and Plant Vogtle was transferred from Atlanta staff to the new Augusta staff toward the end of 2001. By mid-2002, the Augusta staff was fully operational.
With few exceptions, radiochemical analyses on samples collected were performed under contract at the Environmental Radiation Laboratory (ERL) at the Georgia Institute of Technology in Atlanta. EPD also established limited laboratory capabilities in the Augusta office with a liquid scintillation counter to perform routine tritium analyses on all water samples not requiring distillation. EPD has also continued to perform limited confirmatory and operational analyses in its Mobile Radiation Laboratory (MRL) based in Atlanta.

Section B Environmental Radiation Program Activities

RADIOLOGICAL SAMPLING PROGRAM
The Environmental Radiation Program conducts routine environmental sampling activities throughout the year around nuclear facilities that may impact the State's environment, including facilities in Georgia, as well as facilities that are adjacent to the borders of Georgia. These facilities are as follows:
1) USDOE's Savannah River Site in Aiken and Barnwell Counties, South Carolina 2) Georgia Power Company's Vogtle Nuclear Station in Burke County 3) Georgia Power Company's Edwin I. Hatch Nuclear Station in Appling County 4) Alabama Power Company's Farley Nuclear Station in Houston County, Alabama 5) Kings Bay Nuclear Submarine Base in Camden County 6) Georgia Institute of Technology's Neely Nuclear Research Center (Research Reactor) 7) Dawson Forest Wildlife Management Area in Dawson County (Decommissioned) 8) TVA's Sequoyah Nuclear Plant in Hamilton County, Tennessee. 9) Duke Power Company's Oconee Nuclear Station in Oconee County, South Carolina

A wide variety of environmental media are sampled and tested around these facilities, including thermoluminescent dosimeters (TLD) for monitoring direct radiation, air , precipitation, soil, vegetation, milk, assorted crops, surface (river) water, groundwater, fish, seafood, and river sediment. Descriptions of these environmental media and their respective collection frequencies follow.

Direct Radiation (TLDs)

Figure B-1 TLD Dosimeters

Thermo-luminescent dosimeters (TLDs) are collected from 228 locations around Georgia to measure exposure from direct gamma radiation in the environment. In 2002 EPD added 6 TLD monitoring locations around the Savannah River Site. Direct radiation exposure measured by TLDs in the environment may come from several sources, including gamma radiation from naturally occurring radionuclides in soil, cosmic radiation from outer space, gamma radiation from air-borne discharges at nuclear facilities, and from gamma radiation associated with fallout deposited in soil. Georgia uses a special type of TLD, which is also capable of recording other types of radiation exposure, including beta radiation and low-energy x-rays. All environmental TLDs are exchanged on a quarterly basis at active facilities. Since Dawson Forest is a decommissioned facility, TLDs are changed less frequently (semi-annually). TLDs are typically mounted two meters above the ground to a tree or to a telephone pole, using a plastic "cricket cage" holder.

Air Samples
Continuous air samples are collected from 17 locations near several major facilities, as recommended by the US Nuclear Regulatory Commission and US Department of Energy, including Plant Hatch, Plant Vogtle, Plant Farley, and Savannah River Site. Samples collected include biweekly particulate filters, bi-weekly charcoal cartridges, and monthly silica gel cartridges (at selected locations near SRS for tritium H-3).

Figure B-2 Air & Precipitation Sampler

In 2002 EPD increased the sample collection frequency to bi-weekly for air and tritium testing around the Savannah River Site. Testing includes alpha, beta, H-3, gamma isotopic (Cs-137, etc.), radioiodine (I131), strontium (Sr-89 & Sr-90, at selected locations), and plutonium (Pu-238 & Pu-239, at selected locations). Screening for trace Noble gases on the charcoal cartridges is also performed.

Precipitation Samples
Continuous precipitation samples are collected on a monthly basis from 11 locations near Plant Vogtle and the Savannah River Site. These samples are collected in a onesquare-foot rain-pan collector and deposited into a 20-liter bottle. Testing includes alpha, beta, tritium (H-3), gamma isotopic (e.g., Cs-137), strontium (Sr-89 & Sr-90, at selected locations), and plutonium (Pu-238 & Pu-239, at selected locations).
Soil Samples
Soil samples are collected annually from 50 locations around all nuclear facilities, in order to test for potential build-up of man-made radionuclides deposited in soil via fallout. Over the past three years EPD has increased soil sample locations by 13 sites. Naturally occurring radionuclides, which contribute to direct radiation exposure, are also tested in soil. Representative samples of the top 2 inches of undisturbed soil are collected in a 500-milliliter container. Testing includes gamma isotopic (Cs-137, naturally occurring radionuclides: Ra-226, Ra-228, K-40; etc.), strontium (Sr-89 & Sr-90, at selected locations), and plutonium (Pu-238 & Pu-239, at selected locations).

Section B Environmental Radiation Program Activities

Vegetation Samples
Vegetation samples of green, leafy grasses are collected quarterly from 47 locations (6 additional sites have been added over the past three year period) around all active nuclear facilities. EPD tests for recent deposition (fallout) or uptake of man-made radionuclides in vegetation that could enter the food chain. Sampling at Dawson Forest WMA is less frequent as it is decommissioned. Representative samples of the vegetation are collected in 500-milliliter containers. Larger size samples (up to 5 gallons) are required when more extensive testing is performed near SRS. Testing includes gamma isotopic (Cs-137, naturally occurring radionuclides: Be-7, K-40), tritium (H-3), strontium (Sr-89 & Sr-90, at selected locations), plutonium (Pu-238 & Pu-239, at selected locations), and alpha/beta screening (at selected locations).
Milk Samples
Raw, unprocessed milk samples are collected monthly from 11 dairies near three facilities: Plant Hatch, Plant Vogtle, and the Savannah River Site. Over this monitoring period, four more dairies have been added for sampling. One gallon samples are collected at these dairies, primarily by the Georgia Department of Agriculture field inspectors. Testing includes gamma isotopic (e.g., Cs137), ultra-low-level radioiodine (I-131), tritium (H-3), strontium (Sr-89 & Sr-90), and natural potassium (for quality assurance purposes).
Crop and Game Samples
For the past three years, EPD, in conjunction with the Georgia Department of Agriculture has collecting samples from four commercially-grown crops: (1) corn, (2) peanuts, (3) pears, and (4) pecans. Samples taken from 15 locations in Georgia are analyzed to determine if radionuclides enter the food supply. These radioisotopes include Cesium-137, Hydrogen-3 (tritium), Potassium40, Plutonium-238 & -239, and Strontium-89 & -90. Additionally, DNR (Wildlife Resources Division's Game Management) has provided deer from 5 zones in East Central Georgia, along the Savannah River. EPD analyzes these deer samples for the presence of radioactive materials.

testing program) or one liter (for quarterly or semi-annual collections).

High-priority surface water samples are collected continuously and retrieved on a weekly or biweekly basis from a network of 7 water samplers on the Savannah River. This network, which uses special-purpose, sequential / composite water samplers operated by the DNR Environmental Radiation Program, stretches over a 70-mile stretch of the Savannah River, from Augusta to the US-301 bridge. The primary purpose of this network is to monitor each outfall to the Savannah River. These samplers are used to collect individual, weekly, one-gallon aliquots, which may be tested on an individual basis (weekly basis) or on a monthly basis (composite of 4 weeks), as needed. Additional, monthly, composite split-samples are collected at four other locations, on the Savannah River and on the Altamaha River, for DNR by Georgia Power Company. Both groups of samplers (DNR & GPC) samplers are strategically placed to monitor each major nuclear facility's discharge into Georgia waters. Two continuous water samplers are also strategically placed near drinking surface water supply intakes for the City of Augusta and for the City of Savannah (Port Wentworth), in order to assure that the water supplies are adequately monitored on a monthly basis for possible radionuclides.

Groundwater Samples
Groundwater samples are collected Figure B-4 Underflow Study Groundwater Sampling by on a annual basis from available EPD and SRS Personnel groundwater supply wells at 76 locations surrounding nuclear facilities. EPD added 42 groundwater sampling locations in 2002, most of these near SRS. The majority of wells tested draw water from relatively deep aquifers (generally 70 to 300 feet). Testing includes alpha, beta, tritium, and gamma-emitting isotopes (e.g., Cs137). Strontium and plutonium testing is not conducted unless excess alpha/beta emitters are detected. Naturally occurring radionuclides (such as Ra-226, Ra228, natural Uranium) are also tested occasionally, when excess alpha/beta emitters are detected. EPD cooperatively collected 40 samples from 8 well clusters in Burke County, in conjunction with an underflow study conducted by the US Geological Survey and the Georgia Geological Survey. EPD is measuring tritium levels from groundwater migrating westerly from South Carolina. EPD jointly collects the underflow study groundwater samples with Savannah River Site personnel.

Sediment sampling is conducted at the following facilities:
a) Plant Hatch: Samples for Hatch Nuclear Plant network are collected over a 100-mile-plus stretch of the Altamaha River, beginning above the US Highway 1 bridge in Appling County to the mouth of the Altamaha River in Darien, Georgia.
b) Plant Vogtle & Savannah River Site: Samples for the Savannah River Site and Vogtle network are collected over a 190-mile stretch of the Savannah River beginning at the Augusta Lock and Dam to the mouth of the river in Savannah, Georgia.

d) Naval Submarine Base, Kings Bay: Samples for Kings Bay are collected from Cumberland Sound, Kings Bay, and various tributaries in close proximity to the sub base.
e) Oconee Nuclear Plant: Samples for Oconee are collected from several locations in Lake Hartwell.
Fish Samples
Fish and shellfish samples are collected from 21 locations annually. DNR staff (from the EPD Environmental Radiation Program, Coastal Resources and Wildlife Resources Divisions) catch these fish. These samples are collected from the Savannah River, the Chattahoochee River, the Altamaha River, and along the Georgia coast, including Cumberland Sound. Facilities monitored include Plant Hatch, Plant Farley, Plant Vogtle, the Savannah River Site, and US Navy Kings Bay Figure B-6 Fish Collection by DNR Submarine Base. Several varieties of fish are typically collected, including largemouth bass, panfish, and catfish, in freshwater areas, and sea trout, flounder, or red drum, in saltwater areas. Shellfish and marine samples, including shrimp and crab, are also collected from saltwater areas.

Coastal Samples
Various types of samples are collected along the Georgia coast, including shrimp, crabs, sediment and water. Coastal samples are collected off shore of the Savannah River (downstream of SRS and Vogtle), the Altamaha River (downstream of Plant Hatch), and Kings Bay (near the Kings Bay Submarine Base).

Real-time direct radiation monitoring with a Micro-R meter instrument is performed at each TLD location, during the TLD change-out cycle, in order to determine current conditions. EPD is also in the process of installing on-line, continuous, real-time radiation monitors in the environment, near several facilities. These monitors will be able to provide up-to-date, 24hour monitoring results for direct radiation in critical areas.

Remote Real-Time Gamma Monitoring
Remote, real-time gamma-dose monitors are located near each nuclear electrical generating plant in Georgia, as well as near the Georgia Tech Research Reactor, which has decommissioned. These monitors measure the gamma radiation dose every 5 minutes. Results are transmitted to a DNR central control unit each day. Any significantly elevated readings are sent immediately and alarms are activated.

needed. It is especially well suited for testing of short-lived nuclides, that otherwise may decay

before testing in the lab. It also provides a more representative picture of what materials may be

on the bottom, as it is able to detect radioactive materials through at least 12 inches of sediment

layer. Traditional sediment sampling only reaches the top 4-6 inches.

This instrument has proven to be particularly invaluable in several situations: (1) Several scrap-metal and waste-related incident responses requiring immediate, on-scene identification of gamma-emitting radioactive materials, were handled more easily with ISGS, with reduced risk of injury to personnel.

(2) Better underwater assessments of impacted areas of the Savannah River near the Savannah River Site were performed using the ISGS. This utilization also permitted testing for short-lived materials that could otherwise decay before testing could occur at a fixed laboratory.
(3) Suspect areas have scanned to determine (and to quantify) whether any low-level, manmade contamination was present.
(4) Dose characterization studies have been conducted at some areas using ISGS. This utilization permits dose to be traced and assigned to various natural radionuclides (and some man-made, fall-out radionuclides) in the soil and surrounding structures.
(5) Airborne Argon-41 plumes have been traced with ISGS.

Figure B-14 Florida, North Carolina, and Georgia Mobile Labs at Joint Venture Exercise

The Federal Emergency Management Agency (FEMA) evaluates radiological emergency preparedness exercises at commercial nuclear power facilities. EPD participates in three evaluated radiological exercises every two years. FEMA consistently has reported that the EPD emergency response capability for protecting the health and safety of Georgia's citizens in the event of a radiological incident as "adequate", and in many instances as "superior".

In addition to participation in radiological exercises, the

Environmental Radiation Program, in conjunction with

the Radioactive Materials Program, has responded to 84

incidents involving radioactive materials during this report period. These incidents have included

minor incidents at radioactive materials licensees as well as transportation-related investigations.

Over half of the incidents involved contaminated scrap metal detected at landfills and buildups of

naturally occurring radioactive materials (NORM) in manufacturing process equipment. There

are a few unusual incidents. In one incident the Federal Bureau of Investigation requested

identification of a mailed package that was radioactive. The FBI, fearing a radioactivity

dispersion device, wanted EPD to characterize the package, which turned out to be a strong beta-

emitter, later determined to be Sr90. EPD took possession of the package for later safe disposal. Although none of these incidents during this reporting period resulted

that the material involved needs to be quickly identified without undue risk to the investigator.

EPD routinely uses a portable gamma spectrometer to help in the field identification of

radionuclides. In most cases, the source of radiation is NORM deposited on the surface

equipment. However, during one response, EPD personnel determined the source of radiation to

be a radioactive gage that had been improperly disposed.

Georgia Environmental Radiation Surveillance Report 2000-2002 Section B Environmental Radiation Program Activities

In April 2002, Georgia had the unprecedented opportunity to participate in an exercise alongside the bulk of the federal resources that together represent the Federal Radiological Monitoring and Assessment Center (FRMAC), the Aerial Measurement System (AMS) and the Advisory Team for Environment, Food and Health (A-Team). The Joint Venture ingestion pathway exercise (IPX) extended over 3 days, and included participation by state radiological health personnel from Alabama, Florida, Georgia, North Carolina and South Carolina, as well as federal participants. The exercise simulated a major release of radioactive materials affecting both Georgia and South Carolina. Staff of both the Environmental Radiation Program and the Radioactive Materials Program were fully involved in the exercise, as were contract laboratory personnel from Georgia Tech.

Section C - Laboratory and Analytical Programs

Routine, detailed laboratory analyses of

environmental samples are performed at the

Department's Environmental Radiation

Laboratory (ERL), a low-level environmental

radiation testing facility. This facility, located

on the Georgia Tech campus, is operated

jointly by the Environmental Protection

Division and the Office of Interdisciplinary

Programs of the Georgia Institute of

Technology. Special samples from emergency

response and clean-up situations are tested in

the Department's Mobile Radiation Laboratory

(MRL), as needed. Expedited H-3 testing

Savannah River, for early-warning purposes, is

a new function now being performed by Ga-

DNR's Augusta Radiation Laboratory (ARL). Figure C-1: ARL Analyst Testing River Water for

H-3 with Low-Level Liquid Scintillation Counter

in-situ is another lab-related activity, which is

conducted, as needed, with in-situ Gamma Spectrometer (ISGS).

Environmental Radiation Lab (ERL)

The ERL has a wide variety of radioanalytical instruments, a radiochemistry lab, and several experienced

radiochemists, all of which are necessary to support a complex environmental-monitoring mission. This

mission includes nuclear facility testing, Statewide drinking water testing, and emergency-related

missions. Due to the broad spectrum of radionuclides in use at facilities monitored by DNR, the ERL has

to be better equipped and better prepared than many radiochemical labs. In addition to the usual alpha,

beta, gamma-isotopic, and H-3 testing performed by many labs, ERL also performs a number of special

radionuclide tests including gamma radiation dosimetry, Srontium-89/90, Iodine-129,

Radium-226/228, Total Uranium, Uranium-

and Americium-241. An overview of ERL's

testing details and associated equipment are

provided below.

Direct-Radiation Dosimetry - TLDs (ThermoLuminescent Dosimeters): Gamma radiation energy, which is absorbed by TLDs while located in the field, is later tested at the ERL lab with a TLD reader (Figure C-2). This instrument heats up the TLD dosimeter and monitors it's light output to quantify the level of radiation to which it was exposed. This measurement is used primarily to quantify penetrating gamma radiation dose, but it is also
Georgia Environmental Radiation Surveillance Report: 2000 2002
Section C Laboratory and Analytical Programs C-1

capable of detecting and quantifying dose due to less energetic x-rays and beta particles. TLDs are individually calibrated at least once per year with a National Institute of Standards and Technology (NIST) traceable Cs-137-calibration-irradiator.
Gamma-Ray Spectrometry Most environmental samples at the ERL are first tested, using gamma-ray spectrometry, for many possible gamma-emitting radionuclides, such as Be-7 (natural), K-40 (natural), Cobalt-60, Iodine-131, Cesium137, Radium-226 (natural), Radium-228 (natural), etc. This test is performed first in order to quantify any short-lived gammaemitting radionuclides, such as I-131, which Figure C-3: Gamma Spectrometer with Automatic may be present. Additionally, gamma Sample-Changer Used for Low-Level Testing of Air, spectrometry (which is essentially a non- Milk, River Water, and Vegetation Samples by the ERL destructive test) must be performed prior to other radiochemical tests, which usually require ashing and dissolving the sample in strong acids. The ERL has four medium-to-high energy gamma detection systems, including one automatic system that is capable of handling up to twelve samples un-attended (Figure C-3). Calibration checks are performed on a daily-basis, as a part of the quality assurance process, using NIST-traceable standards (Figure C-4).

X-Ray Spectrometry, Including I-129, and Associated Radiochemistry: The ERL has one x-ray spectrometer system, which is used primarily for radionuclides that can only be identified and quantified through their x-ray signature, including Fe-55 and I-129 (Figure C-5). X-ray spectrometry is also useful for testing naturally occurring Pb-210, as well as for testing higher concentrations of other x-ray emitting radionuclides, such as Pu-238, Pu-239, and Am-241. Calibration checks are performed on a daily-basis, as a part of the quality assurance process, using NIST-traceable standards.

I-129 testing is the main on-going mission for the x-ray spectrometer at ERL. Testing for I-129 near SRS is important, due to its long-lived nature and due to it's high dose-percent ranking in air and water pathways by SRS. SRS's data also suggests that I-129 has moved up the food chain, concentrating in onsite deer (WSTC-IM-90-60, Vol.-II, p, 713). ERL regularly detects long-lived I-129 in water samples from Four-Mile Creek (SRS). This testing requires extensive radiochemical processing to extract and concentrate the I-129, prior to x-ray spectrometry. Chemical iodine carriers must be added during testing, to monitor and correct for chemical recovery.

Fe-55 testing was another important mission for the x-ray spectrometer during D&D at the Georgia Tech Research Reactor. Fe-55 is a low-energy x-ray emitter produced through neutron activation of nonradioactive iron in reactors. Since D&D involved cutting and removing many iron-rich components, such as iron-leaden, high-density concrete surrounding the reactor vessel, it was important that Fe-55 testing be performed on air samples, in addition to testing for higher-energy neutron-activation radionuclides, such as Co-60 and Eu-152.

Alpha-Particle Spectrometry and Associated Radiochemistry: The ERL has sixteen alpha-particle spectrometers, which are used to measure and quantify non-volatile, alpha-emitting radionuclides, including Pu-238/Pu-239+240, Am-241, Cm-244, U-233/ U-234/U-235,/U-238, etc. Many samples, including air filters, water, soil, sediment, fish, and food products, especially have to be tested for Pu238/Pu-239, due to plutonium processing and waste facilities at SRS. This first requires specialized radiochemistry in order to extract the chemical elements of interest, followed by electroplating onto metal discs. NIST-traceable radionuclide tracers must also be added to these samples to measure chemical recovery during this process. Calibration checks using NIST-traceable standards are performed on at-least a weekly-basis, and more often when running samples, as a part of the quality assurance process. ERL employees illustrate several steps necessary for the testing of environmental samples for plutonium, below (Figure C-6).

Alpha-Beta Counters and Alpha-Scintillation Counters

Alpha-Beta testing is performed after gamma-ray spectroscopy (primarily on water samples, air filters, and smear samples) as a screening tool for many radionuclides (such as Sr-90, Pu-238, and Pu239) that don't emit detectable gamma rays. The ERL had three automatic alpha-beta counters (Figure C-7), as of the 2000-2002 period. Calibration checks are performed on these systems on a dailybasis, as a part of the quality assurance process, using NIST-traceable standards.

The majority of samples tested by the ERL for alpha-beta activity are

air filters, which may be tested directly, and water samples, which

must be boiled down and plated out onto planchets. The ERL also uses Figure C-7: Analyst Entering

their Alpha-Beta counters extensively for specialized radiochemical Sample Information into

testing of high-dose radionuclides. Sr-89/Sr-90 is one example, in

Alpha-Beta Counter

which extensive radiochemical separation must be performed to

extract and concentrate strontium from samples prior to alpha-beta counting. Many samples, including air

filters, water, soil, sediment, fish, and other food products, must be tested for Sr-89/90, due to the large

inventory of Sr-90 in wastes and in seepage basins at SRS. Specialized testing is also necessary for

naturally occurring radionuclides, such as Ra-226, Ra-228, and Uranium, in Drinking Water. Over 1000

samples per year of community drinking water are typically tested by the ERL, using this equipment.

Specialized alpha-scintillation counters, with Lucas cells to contain radon gas, are also used by the ERL for alpha counting of drinking water samples. These instruments (Figure C-8) are used specifically for testing volatile alpha-emitting radionuclides, such as Rn-222 (Radon gas), that evolve from Ra-226 in the water. The ERL currently has six alpha-scintillation counters in their inventory.

Section C Laboratory and Analytical Programs C-5

Ashing and Microwave Digestion of Solid Samples prior to Radiochemical Testing
Solid samples, such as air filters, soil, sediment, fish, and food products must go through two steps (Figure C-9) to get them into solution, prior to running strontium and plutonium chemistry. Ashing is the first of these two steps. This reduces the sample volume and effectively concentrates the sample by as much as a factor of ten (for fish and food product samples). It also eliminates organics, which can cause problems during subsequent acid digestion. Ashing is performed at temperatures up to 550oC, which is sufficient to get rid of all carbon in the sample. The ERL has two ashing ovens dedicated to this job.
After ashing is complete, an aliquot (up to 3g) of ash is then dissolved in concentrated acids, under heat and pressure, with a microwave digester. This process totally dissolves all solids, thus insuring that the entire matrix is tested. Total dissolution is preferred over other commonly used methods, such as acid leaching, as this insures that all forms of strontium and plutonium will be dissolved for testing. Some forms of strontium or plutonium that are high-fired or ceramic in nature may not be fully dissolved by other methods. The ERL has one microwave digester dedicated to this job.
Once the samples are in solution, they can then be tested by the radio-chemist for the particular element of interest. Tracers or chemical carriers are usually added at this step, although they may be added earlier, in some cases. The ERL has four fume hoods and four radio-chemists to perform radiochemical procedures and other screening procedures.

Beta-Gamma Coincidence (BGC) System
The BGC system was once the primary means used by the ERL to perform low-level I-131 testing of milk and drinking water samples. This function has now been largely replaced with a super-sized gamma spectrometry detector and automatic sample gamma-changer system (pictured earlier in Figure C-3). The BGC system required that iodine radiochemistry be performed on samples, reducing the sample to a " wide plastic button sample-mount, prior to counting the sample. The newer system doesn't require any radiochemistry, as samples can be counted directly in a 3-L Marinelli beaker. The BGC system is still being maintained for other possible work in the future, but it isn't being used on a regular basis, currently.
Georgia Environmental Radiation Surveillance Report: 2000 2002 Section C Laboratory and Analytical Programs C-6

Liquid Scintillation Counters (LSC) and Associated Equipment for Testing Tritium (H-3)

Most samples in the SRS network, including air, rain, river water, groundwater vegetation, milk, fish, and food products, are tested for H-3, due to the large inventory of H-3 at SRS. Water samples from all of the other nuclear-facility monitoring networks are tested for H-3, as well. Samples are tested in liquid scintillation counters (LSC's) after pre-processing to remove impurities that can interfere with the test. The ERL had two low-level LSC's available for use during this report period (Figure C-10).

ERL distills all samples (Figure C-11) and collects the distilled

water, whether water, milk, or solids, to remove possible

interfences and to insure a constant level of quench (which also

insures a constant and reliable efficiency for counting). Simple

distillations are performed on water samples. Solid samples, such as vegetation, fish, and food products, must be distilled using a reflux method. This minimizes organic contamination of the

Figure C-10: ERL Analyst
Loading Processed Samples Into LSC for H-3 Testing.

distilled water, which is trapped. Organic contamination is

undesirable, as it can produce false positives for some time after distillation, due to chemi-luminescence.

H-3 air samples, which are collected on silica gel, must also be distilled with the reflux method, to avoid

possible over-heating.

Specialized low-level H-3 testing is performed on groundwater samples from the deeper aquifers. Low level testing of these aquifers for H-3 is necessary to provide an early warning, in case H-3 begins to reach these aquifers. Low-level testing is also necessary insure that H-3 hasn't already reached those aquifers. Low-level H-3 testing is accomplished with electrolytic enrichment (Figure C-11) of the
sample's H-3. This process preferentially-liberates lighter hydrogen atoms (H1) from water as hydrogen gas, as opposed to heavier hydrogen atoms (H3), which remain in the water sample. Sample enrichment factors of up to ten are achieved by the ERL, using this procedure.

Quality Assurance
The Georgia Environmental Radiation Laboratory's (ERL) quality assurance program is an integral part of lab operations. A valid, on-going quality assurance program is necessary to maintain lab credibility. The ERL's quality assurance program consists of several elements. These include (1) personnel skill qualifications, (2) training programs, (3) procedural development, (4) utilization of approved standard methods, (5) participation in cross-check and blind sample programs, (6) programs for regular maintenance and calibration of analytical equipment, and (7) quality assurance reviews and audits by EPA. A brief discussion of quality assurance items of interest are presented below below:
DOE-QAP Program Participation
During the 2000-2002 period, the DOE-QAP program was the primary external quality assurance crosscheck program in which the Ga-ERL participated. ERL's participation in this program was extensive, including alpha, beta, H-3, gamma isotopic, Sr-89/90, Pu-238/239, U-238, Am-241, and Cm244. During the June-2000 - June-2002 period, ERL passed all reported QAP tests, with an overall acceptance rating of 87%, and a 17% warning rating. Less than 2% of all ERL-reported results were more than 25% outside of the expected range. Detailed results by sample type and by radionuclide are provided graphically by percent-of-expected value in Figure C-12 (next page). A summary of QAP results is also presented in a tabular format (Table C-1 next page).
The DOE Quality Assurance Program (QAP), which is run by DOE's Environmental Measurements Laboratory (EML), is an external, independent performance evaluation program designed to test the quality of environmental radiological measurements reported by DOE contractor and subcontractor laboratories. The program provides DOE with complex-wide comparability of environmental radiological analyses. DOE laboratories and commercial laboratories performing environmental radio-analytical measurements for EM are required to participate in QAP.
QAP provides four matrices for testing. The distribution typically consists of a simulated air filter, 200 g of soil, 100 g of vegetation, and 450 mL of spiked water. These natural matrix and synthetic samples, prepared and analyzed at EML for as many as 15 radionuclides, are distributed semi-annually to DOE contractors and other participating-laboratories. QAP is unique in supplying multi-matrix, multi-nuclide samples. Sample distributions are in March and September without any financial obligations for the participating laboratories.
Participants can use any analytical method and are required to analyze only those matrices/nuclides for which they contract to DOE. Participants' results must be reported to EML within 90 days. A summary of the reported results is available to participants 48 hours after the reporting deadline via the internet. This rapid access to the data is another unique feature of QAP. The reported results are then compared with historically derived control limits. An evaluation report is available on the EML Web Site within 30days. The participating laboratories and their reported results are identified. QAP reports are posted on the EML Web site in July and January.

EPA's Quality Assurance Crosscheck Program

Beginning in 2002, the ERL also participated in EPA's QA-crosscheck program, which is currently handled by a private contractor (ERA). ERL participated for many years in EPA's QA-crosscheck program, until EPA discontinued it, due to budget cuts. This program was only recently re-started under private contractors, which is the reason that the ERL didn't participate until 2002. Participation and acceptable lab results are mandatory to maintaining a certified lab that can test community drinking water samples.
ERL is one of the few labs in the nation currently certified and QA'd by EPA and ERA to perform radiological testing of community drinking water supplies for Ra-226 and Ra-228. ERL's participation in this program was extensive, including alpha, beta, H-3, gamma isotopic, Sr-89/90, I-131, Ra-226, Ra-228, and Uranium. ERL passed all reported QA tests, with an overall acceptance rating of 100% (no warnings). Detailed results by radionuclide are provided graphically by percent-of-expected value in Figure C-13 (below).

DNR's Augusta Radiation Laboratory (ARL)
At the end of 2001, DNR started up a small laboratory at their district office in Augusta. This lab was designated as the Augusta Radiation Lab (ARL). Currently it is dedicated primarily to testing over 600 river water and drinking water samples per year for H-3, on an expedited basis (Figure C-14). This is necessary in order to provide reasonable assurances, to downstream river water users as well as the local fishing public, that H-3 isn't a problem. ARL provides timely, high-quality data through a combination of continuous river water samplers, operated by DNR, as well as with a special low-level liquid scintillation counter (LSC), used to test the samples.
The use of continuous river samplers to collect composite samples, as opposed to grab samples, is the first step necessary for quality river-water output data. Without quality input samples, output quality would be meaningless. Although sampling is not considered to be a laboratory-related item, it is critical precursor. The combined product has been of high-enough quality to successfully calculate the total H-3 activity released to the river, with good agreement to what was actually released.
The ARL regularly (monthly) re-calibrates their LSC's H-3 quench-curve and efficiency using a NISTtraceable quench-curve calibration set. They also run calibration checks, prior to each batch of samples tested. Their sample counting procedure automatically take into account any minor changes in the system, by including a standard with each batch to re-generate a batch-specific efficiency factor.
Figure C-14: H-3 Sample Preparation and Testing by the ARL

Analyst preparing samples for LSC: Samples are prepared for the LSC by pipetting10 ml of nondistilled water samples into 20 ml glass LS vials, and subsequently adding 10 ml of LS cocktail. Cloudy samples are pre-filtered, as needed.

Analyst loading samples into LSC: Samples are loaded into the LSC, along with a backgrounds and standards, and subsequently counted, using automatic quench correction and luminescence monitoring.

ARL does not use distillation, when processing samples for H-3 testing, as compared with the ERL, which does use distillation. Since expedited testing was the critical mission for the ARL, a decision was made to skip distillation in this situation. Since other labs in the area (SRS, SC-DHEC) also do direct testing without distillation, comparable results should be expected. ARL QA crosschecks for H-3 with the ERL indeed indicate good agreement, as demonstrated in Figure C-15 below.

Mobile Radiation Lab
The Department's Mobile Radiation Lab (MRL ... Figure C-16), which has been in operation since 1980, provides for emergency and clean-up-related testing of samples in the field, as needed. It is equipped mainly to handle analytical needs associated with emergency-level radioanalytical testing. Sample testing is geared toward direct testing, with minimal sample preparation. There are no provisions for advanced radiochemistry. When on standby in Atlanta, the MRL is routinely utilized for testing of samples from various inspections and minor incidents. Occasionally, the MRL participates in nuclear emergency exercises at various nuclear sites in Georgia. Over the years, the MRL has been utilized most for clean-up related activities, which required a long-term presence on site. The last major utilization of the MRL at a site was the cleanup of the Radiation Sterilizers, Inc. (RSI) site in Decatur, GA. This cleanup required almost four (4) years to complete. During that time, EPD personnel performed radiochemical analysis of more than 2000 samples.

Figure C-16: Mobile Radiation Laboratory

The function of the MRL is to count, identify, and quantify the radionuclides in field-prepared samples, based on the radioactive emissions observed in these samples. Testing is conducted for the following radionuclides and gross-nuclide-screening: Gross alpha, gross beta, gamma isotopic, x-ray isotopic, tritium (H-3), C-14, P-32, etc. In order to conduct these tests, four types of radioanalytical detection and analysis systems are used. A summary of the instruments utilized is as follows:

Section D Savannah River Site (SRS) and Vogtle Electric Generating Plant (VEGP)
Georgia DNR's most extensive environmental radiation monitoring network is focused on an area in Georgia adjacent to and downstream of the U.S. Department of Energy's Savannah River Site (SRS - Figure D-1) in South Carolina and Georgia Power Company's Vogtle Electric Generating Plant (VEGP - Figure D-2) in Georgia. A commercial radioactive waste burial ground facility, operated by Chem-Nuclear (Figure D-3 next page), is also located near the monitored area (adjacent to SRS and Lower Three Runs Creek). Because of the relatively close proximity of the Savannah River Site to the Vogtle Electric Generating Plant, a single combined monitoring network has been utilized by DNR since approximately 1978.

Figure D-1 Savannah River Site (Old Reactor)

Figure D-2 - Vogtle Electric Generating Plant

Georgia Power Company's Vogtle Electric Generating Plant (VEGP) is a two-unit Pressurized Water Reactor (PWR) facility located on a 5-square-mile tract of land adjacent to the Savannah River in Burke County, Georgia approximately 20 miles southeast of Augusta. This facility, which was supplied by the Westinghouse Corporation, and which is operated by Southern Nuclear Operating Company, has been in operation since 1985.
The U.S. Department of Energy's Savannah River Site (SRS) is a large, U.S. Government complex that has been operated since the early 1950's, primarily for the production of special nuclear materials (including tritium and plutonium) used in nuclear weapons. The SRS area includes numerous airborne emission points, which are distributed over a 300-square-mile area, as well as numerous waterborne emission points, which feed into a 30-mile stretch of the Savannah River. Westinghouse Savannah River Company (WSRC) currently operates SRS under contract to DOE. Facilities at SRS include several mothballed reactors, two large radiochemical separations plants, a large high-level waste processing plant, a radioactive-waste incinerator plant, two high-level-radioactive-waste tank farms, several radioactive waste burial grounds, and fuel & target plants.
Although the reactors at SRS are no longer operating, millions of gallons of highly radioactive liquid waste and thousands of spent fuel elements still pose a significant, long-term environmental risk, which require continued monitoring. Future missions at SRS, including the disassembly and re-processing of plutonium pits and the recovery and recycling of excess plutonium and uranium for mixed-oxide reactor fuel, will also require continued vigilance for many years, due to the long-lived nature of the processed material and possible releases from accidents or reprocessing operations. Another significant mission, which is currently underway, is the production of replacement tritium (H-3), which will be processed and extracted at SRS in the near future. This will likely result in increased airborne H-3 releases to the off-site environment starting around the end of 2004.
Georgia Environmental Radiation Surveillance Report 2000 2002
Section D Savannah River Site (SRS) and Vogtle Electric Generating Plant (VEGP) D-1

During the period that DNR has monitored SRS, several Site-related radionuclides have been detected periodically by DNR, including Tritium (H-3), Cobalt60 (Co-60), Strontium-90 (Sr-90), Iodine-129 (I-129), Cesium-134 (Cs-134), Cesium-137 (Cs-137), Plutonium-238 (Pu-238), and Plutonium-239 (Pu-239). During the current (2000-2002) period, all of the above SRS-related radionuclides (except for Cs-134) were detected:

1) H-3 was detected in many samples from a 400

square-mile area of land in Georgia adjacent to

SRS, including air (up to 5x background), rain (up

to 5x), groundwater (up to 5x), vegetation (up to

13x), milk (up to 3x), deer (up to 3x), and crop

samples (up to 2x). DNR believes airborne

emissions from SRS account for the majority of Figure D-3: CHEM-Nuclear Waste Burial Site

these results. SRS contributed approximately 99%

(Adjacent to SRS, Near Barnwell, S.C.)

of all of the local airborne H-3 released during this

period based on available effluent reports. Approximately 97% of SRS airborne H-3 releases were from

active facilities, with the remainder (3%) from diffuse sources, such as ponds and creeks based on

available environmental reports. A summary of H-3 related findings is presented in Table D-0-A.

2) H-3 was also detected in river water samples (Table D-0-A) over a 130-mile stretch of the Savannah River and its tributaries (up to 300x background adjacent to SRS and up to 16x background downstream of SRS). H-3 was also detected in fish samples over the same area of the river (up to 230x background

near SRS and up to 9x background downstream of SRS). Water-borne H-3 emissions from SRS (which enter the Savannah River from five Site streams) are believed to be the primary source of the measured H-3 during this period: Approximately 90% of local water-borne releases are attributed to SRS, with approximately 10% attributed to VEGP. Since a significant portion of airborne H-3 also re-enters the watershed through precipitation, the percentage of waterborne H-3 attributable to SRS is likely to be higher than 95%, however. SRS releases of water-borne H-3 include active facilities as well as seepage from closed radioactive-waste treatment basins and burial grounds. 3) Long-lived I-129 (up to 8x MDC) was detected in water from Four-Mile Creek, a tributary of the Savannah River. This radionuclide is attributed primarily to seepage (leakage) from closed radioactivewaste treatment basins and burial grounds located at SRS. 4) Elevated Co-60 (up to 22x background), Sr-90, (up to 3x background), Cs-137 (up to 540x background), Pu-238 (up to 3x background or MDC) and Pu-239 (up to 6x background or MDC) were detected in sediment samples adjacent to and up to 100 miles downstream of SRS. Based on observed isotopic ratios, it appears that discharges from SRS may be responsible for approximately 90% of the Cs-137 and up to 80% of the Pu-238 and Pu-239 in the Savannah River downstream of SRS. (Global fallout is probably responsible for the remainder of downstream Cs-137 and Pu-239). Co-60 is attributed both to SRS and VEGP, coming from at least three separate effluent points entering the river. Based on available environmental reports, several SRS on-site streams are also contaminated with these radionuclides, suggesting SRS as a likely source for a significant portion of what was detected offsite. A portion of the off-site Co-60 is may be attributed to VEGP as well as to SRS. However, the majority of Cs-137 is believed to be attributable to SRS, given the reported extensive Cs-137 contamination in SRS creeks. 5) Cs-137 and Pu-239 were detected in several soil samples. Most of the activity in these samples appears to be related to global fallout, with the possible exception of a sample from Shell Bluff Landing, which is in the most predominant downwind direction from SRS. This sample contained the highest percentage of Pu-239 to Cs-137, suggesting that up to 15% of the Pu-239 may be from SRS. (SRS reports an offsite population dose of approximately 121,000 person-mRem for consumption of vegetation, due to SRS-related fallout of Pu-239, through 1995 ...WSRC-TR-970152, Pu-239 p.4). 6) Elevated H-3 (up to 230x Bkg), Sr-90 (up to 5x background), and Cs-137 (up to 220x background) were detected in fish samples adjacent to the SRS area. NRC reporting levels were exceeded in three instances due to SRS-related radionuclides. Projected 30-year cancer morbidity risks at one location (Steel Creek) exceed 10 out-of 1,000,000, due to Cs-137 in largemouth bass. 7) Elevated Cs-137 (up to 4x background) and H-3 (up to 3x background) were detected in deer samples collected in Georgia adjacent to SRS. Projected 30-year cancer morbidity risks adjacent to SRS currently exceed 10 out-of 1,000,000, but more data will be needed to refine this estimate. The source of the excess Cs-137 has not yet been determined, but SRS estimates that offsite-hunters near SRS receive around 2.9 mRem from Cs-137, due to migration of deer from SRS (WSRC-TR-2000-00328, p.121). This compares favorably with DNR's 2002 dose estimate (3.5 mRem). 8) Elevated Sr-90 (up to 4x background) was detected in leafy vegetation from two locations in southeastern Richmond County, near SRS. NRC reporting levels were exceeded at these two locations. (SRS reports an off-site population dose of approximately 66,000 person-mRem for consumption of vegetation, due to SRS-related fallout of Sr-89/90, through 1995 ...WSRC-TR-970152, Sr-89/90 p.4).
During the period that DNR has monitored Plant Vogtle (VEGP), three Site-related radionuclides have periodically been detected in the aquatic environment, including H-3 in river water, Co-58 in river sediment, and Co-60 in river sediment. During the current 2000-2002 period, H-3 and Co-60 were the only man-made radionuclides detected that may be attributed to Site operations:
1) H-3 was detected in river water (up to 50x background) downstream of Vogtle in one sample after a chemistry problem in one reactor (near the end of 2002), which required system shutdown and cleanup.
2) Co-60 was detected in river sediment (up to 7x background) downstream of Vogtle.

Direct Radiation Results (TLDs):
Quarterly direct (gamma) radiation measurements were made with TLDs (Thermo-Luminescent Dosimeters) from 59 locations in the environment, as provided in the TLD (and Air) Network Map (Figure D-6). Direct radiation doses (Table D-1) were within the normal (expected) range (except as noted below), with indicator locations (near Plant SRS and VEGP) measuring slightly less than background (or control) locations (Figure D-4), suggesting no measurable Site-related impact from direct radiation.

SRS/VEGP are probably lower due to the rural environment, with less paved roads and concrete or brick structures, which tend to have higher levels of naturally occurring radionuclides. Based on a review of the soil samples results, naturally occurring radionuclides in the Uranium, Thorium, and Potassium series appear to account for over 99% of the direct radiation dose recorded on the TLDs. Indicator and background locations show similar seasonal variability, typical of natural radon fluctuation.

Dose rates at two TLD locations (Figure D-5) were elevated, relative to previous results starting after the January 2002 change-out. These readings were not site-related. Local construction-related activities involving use of concrete and gravel fill at these sites have been determined to be responsible for these changes. Concrete and gravel contain naturally occurring radionuclides, which contributed to increased gamma-radiation dose rates observed by these TLDs.

Air: Air samples (Table D-2) were collected twice monthly from up to eleven locations in the environment as previously provided in the TLD + Air/Rain map. Samples were tested for alpha, beta, H-3, gammaisotopic (Cs-137, etc.), Sr-89, Sr-90, Pu-238, and Pu-239. Tritium (H-3) was the only Site-related (SRS) radionuclide detected in air samples during the current monitoring period. In addition to H-3, naturally occurring radionuclides, including Be-7 (from cosmic ray interaction in the atmosphere) and Pb-210 (a longlived radon daughter) were also detected, along with beta activity associated with Pb-210.

Tritium from SRS in Air:
Tritium (H-3) was detected in air samples over a 30-mile radius from SRS, with highest concentrations occurring within the predominant downwind-direction envelope (Figure D-7). This envelope represents the relative frequency distribution of wind direction for all meteorological conditions monitored by SRS at their H-Area meteorological tower. It is centered on the F and H areas of SRS, where most of the airborne H-3 is released. Therefore, it should provide a good predictor of where H-3 will go in the environment, not only for air, but also for other airborne pathways, including rain and vegetation.

D-7

As previously noted, most of the airborne H-3 (>99%) is assumed to be from SRS, based on available effluent reports. Concentrations ranged up to approximately 5X the background or detection limit (note Figure D-8 below). Although elevated, all H-3 concentrations were below reporting levels and did not pose a significant risk. Doses from airborne H-3 averaged less than 10 micro-Rem per year.

Figure D-8 Airborne Tritium Concentration Trends at Selected Locations (fCi/m3)

Although H-3 was the only Site-related activity detected in the airborne environment, other naturallyoccurring activity was also detected in air samples, including beta, Be-7, and Pb-210. Naturally occurring Be-7 is a product of cosmic-ray interaction in the atmosphere. Pb-210 is a long-lived radon-daughter product that forms in the lower atmosphere when Rn-222 gas (released from Ra-226 in soil) decays. Since similar results and seasonal variability were observed (Figure D-10 next page) in beta activity from indicator locations (near SRS/VEGP) and from control or background locations, observed beta activity is not likely to be Site-related. Instead, the beta activity detected in the air samples is primarily attributed to naturally occurring Pb-210, which is a beta emitter. A limited group of samples were tested specifically for Pb-210 on a special low-energy gamma detector to confirm the assumed correlation of Pb-210 to beta activity (Figure D-9 below).

Precipitation:
Precipitation samples (Table D-3) were collected monthly from up to eleven locations in the environment as previously provided in the TLD + Air/Rain map. Samples were tested for alpha, beta, H-3, gamma-isotopic (Cs-137, etc.), Sr-89, Sr-90, Pu-238, and Pu-239. Tritium (H-3) was the only Site-related (SRS) radionuclide detected in precipitation samples during the current monitoring period (note H-3 deposition trend in Figure D-11 below). In addition to H-3, un-identified beta activity was detected in some samples. This activity is most likely due to naturally occurring Pb-210, which was detected in air samples but which was below the gamma detection limit for rain.

(pCi/L) and inches of rainfall, provide a useful measure of the total fallout per square meter, which can be used to estimate potential impact to other pathways, such as shallow groundwater. H-3 concentrations (detected) near SRS averaged around 400 pCi/L (2% of SDWA MCL), with peak concentrations up to 1,000 pCi/L. Deposition of H-3 in rain near SRS averaged between 50,000 and 90,000 pCi/m2 per year, peaking at 45,000 pCi/m2 in just one month. Most of the H-3 in rain appears to be deposited between the fall and spring of each year, when easterly winds and rain often occur.
Leafy Vegetation:
Leafy vegetation samples (Table D-7) were collected quarterly from up to seventeen locations in the environment. Samples were tested for H-3, gamma-isotopic (Cs-137, etc.), Sr-89, Sr-90, Pu-238, and Pu-239. Elevated H-3 (up to 13x background) was the only radionuclide detected in these samples during the 20002002 period that is definitely Site-related. Elevated Sr-90 (up to 4x background) was also detected at two locations in southeastern Richmond County near SRS. Given the proximity of these locations to SRS, the excess Sr-90 that was detected may be SRS-related. Cs-137 was also detected in some samples but no significant differences were found between indicator and control samples.

Tritium from SRS in Leafy Vegetation and Sr-90 in Vegetation:
H-3 was detected periodically in leafy vegetation (forage) over a 30-mile radius from SRS. As previously noted, most of this H-3 (> 99%) is assumed to be from airborne H-3 released by SRS, based on available effluent reports. Several mechanisms for transfer of airborne H-3 to vegetation are likely, including earlymorning condensation (dew), direct atmospheric exchange of moisture via transpiration, and rainout of airborne H-3. Highest concentrations were observed within SRS's downwind footprint into Georgia, as provided in Figure D-13, below. Concentrations averaged between 500 and 800 pCi/kg (fresh weight) near SRS, with peak concentrations up to 2,600 pCi/kg. None of the tested locations exceeded the reporting level for H-3. However, two locations exceeded the reporting level for Sr-90 as denoted by the stars in Figure D13. Because of their proximity to SRS, elevated Sr-90 at these locations may be Site-related. (SRS reports an off-site population-dose of 66,000 person-mrem, due to fallout of SRS-related Sr-89+90 onto vegetation ...WSRC-TR-970152, Sr-89/90-p.4).

Groundwater:
Groundwater samples (Table D-4 Monitoring Wells and Table D-5 Public Wells) were collected at least annually from a number of locations in the environment. Samples were tested for alpha, beta, H-3, and gamma-isotopic (Cs-137, etc.). Low-level H-3 testing was performed on some samples from deeper monitoring wells to determine whether H-3 was present. H-3 was the only man-made radionuclide identified (in the monitoring wells) that can definitely be linked to SRS. Slightly elevated alpha and beta activity (probably naturally-occurring Ra-226) was also detected in one monitoring well cluster in the shallow aquifer.

Tritium from SRS in Groundwater in Burke County:
Although tritium was generally expected to be present in the open environment, it was not expected to be in the confined environment associated with deep groundwater aquifers in Georgia. After discovering tritium in drinking water from several relatively deep wells in Burke County around 1991, an extensive testing program was conducted by the Geologic Survey Branch of Ga-DNR, in conjunction with the USDOE. The purpose of the program was to determine the entry mechanism for the tritium contamination and to determine whether any deep aquifers in Georgia were contaminated. Because of the close proximity of these wells to SRS, where ground water was extensively contaminated with tritium, there was initially some concern that the tritium found in the Burke County wells might be migrating directly from the contaminated aquifers under SRS. Tritium concentrations in affected wells in Burke County during the early study period were generally less than 1,200 pCi/L, which is approximately 6 percent of the Safe Drinking Water MCL.
The extensive groundwater-testing program in Burke County included the drilling and monitoring of several test-wells, an examination of existing wells in the area to determine their status, testing of the shallow watertable aquifer, and testing of rainfall that could enter the water-table aquifer. As of this time, no significant tritium contamination has been positively identified in any deep aquifers in Georgia, based on monitoring well data. On the other hand, extensive tritium contamination was detected in groundwater associated with the relatively shallow (up to 200 feet deep) Upper Three Runs aquifer during the 2000-2002 period, as noted in Figure D-14. H-3 concentrations averaged less than 1,000 pCi/L (< 5% of the MCL) during 2000-2002. Contamination appears to be concentrated primarily within SRS's downwind footprint, suggesting a possible connection with airborne (or rain-borne) H-3 from SRS.

The vertical profile of H-3 measured in the primary well cluster TR-92-1 (Figures D-14B and D-14C) demonstrates that H-3 is confined to the Upper Three Runs Aquifer in this well group. It also demonstrates that the H-3 concentration in the Upper Three Runs Aquifer increases slightly with well depth, reaching a peak in sandy portions of the aquifer referred to as the Tobacco Road Sand and Irwington Sand Member formations. The H-3 concentration appears to decline below these formations, and it is just barely detectable in the lower portion of this aquifer, referred to as the Utley Limestone Member. The vertical H-3 profile in the Upper Three Runs Aquifer is believed to reflect the historical rainout of airborne H-3 from SRS, looking backward in time, from top to bottom of this aquifer. After reaching the lower aquifers (Gordon, Dublin, etc.) H-3 was no longer detectable, even with low-level H-3 testing.

Soil (Pu-239 and Cs-137):

Soil samples (Table D-6) were collected from 16

locations in the environment around SRS/VEGP.

Samples were tested for gamma isotopic (including

Cs-137), Sr-89/90, and Pu-238/239. No man-made

radionuclides that can definitely be linked to Site

operations were detected. However two man-made

radionuclides (Cs-137 and Pu-239) were detected in

several soil samples. Both Cs-137 and Pu-239 are

found in global fallout as well as at SRS (on-site). No

significant differences were noted between control

and indicator samples with the exception of one

sample taken from Shell Bluff (Figure D-15).

have a much higher percent Pu-239 (approximately 17%, decay-corrected to 2002, based on data from

WSRC-RP-92-879-Rev-1) due to localized fallout from airborne plutonium discharges at F-Area.

Savannah River Water (Including H-3):

River water samples were collected from ten locations on the Savannah River between Augusta and Savannah on a weekly basis for most locations. Samples were tested for H-3, alpha, beta, gamma isotopic, Sr-89/90, and Pu-238/239 (Table D-10). H-3 was the only manmade radionuclide routinely detected at most locations. I-129 was also detected in Four-Mile Creek (0.4 + 0.1 pCi/L average concentration ... < MCL).

(13 % MCL)

Elevated H-3 was detected in the Savannah River over a 130-mile stretch between Upper Three Runs Creek (U3RC - SRS) and Abercorn Creek downstream in Savannah (Figure D-17). SRS is believed to be the primary source (> 90%), with Vogtle contributing between 5% and 10% for the 2000-2002 period, based on available effluent reports. Additional H-3 also likely enters the Savannah River watershed via rainout of airborne H-3, with SRS contributing approximately 99% for this pathway.

and % MCL in the Savanna River (2000-2002)

A significant portion of waterborne H-3 entering the river from SRS appears to have been discharged into Upper Three Run's Creek (probably from SRS's Effluent Treatment Facility - ETF). ETF processes liquid wastes in batches, removing most radionuclides except for H-3. Beginning the summer of 2000, ETF's discharges of H-3 increased sharply due to the need to process legacy high-level liquid wastes stored in aging tanks. This process will likely continue for a number of years, based on available projections. Due to this process, Upper Three Runs Creek had the highest average H-3 concentration (13,400 pCi/L), which peaked around 46,000 pCi/L in August 2000 (note H-3 trend plots in Figure D-18A on the next page).

Another significant SRS source of H-3 entering the Savannah River is underground seepage from closed radioactive-waste treatment basins and burial grounds. Four-Mile Creek is the primary tributary where this occurs, as it is closest to the waste burial sites. Underground seepage is also headed for Upper Three Runs Creek, but it isn't expected to arrive for several more years. Due to on-going seepage into Four-Mile Creek, this creek had the second highest H-3 concentration (13,200 pCi/L), peaking at 60,000 pCi/L.

Vogtle also contributed a portion of the H-3, as noted above, through periodic batch discharges. The H-3 concentration downstream of Vogtle averaged 2,200 pCi/L, peaking at 11,000 pCi/L between 11/26/2002 and 12/3/2002. This peak was associated with a chemistry problem in one of the reactors, which required shutdown and cleanup.

Downstream H-3 concentrations between US-301 and Savannah averaged between 900 and 1,000 pCi/L, equivalent to 5% of the allowable Safe Drinking Water MCL for the 2000-2002 period. The peak H-3 concentration (3,300 pCi/L) at US-301 occurred during the above-noted chemistry problem at Vogtle. The peak H-3 concentration (2,300 pCi/L) at the City of Savannah's I&D Water Plant intake appears to have occurred in conjunction with waste-tank processing at SRS's ETF facility, which discharges into Upper Three Runs Creek (which also elevated in H-3).

As noted above, long-lived I-129 has been detected regularly, along with H-3, in Four-Mile Creek water, due primarily to now-closed seepage basins at SRS. I-129 in FMC water appears to be trending upward (Figure D-18B) with time, whereas H-3 appears to be trending downward (Figure D-18C) with time. Part of the downward trend in H-3 is attributed to phyto-remediation, a process in which SRS sprays FMC water onto surrounding trees. This encourages increased evaporation and transpiration, and effectively removes some of the H-3 from FMC via the airborne pathway. Theoretically, phyto-remediation should also help remove some of the I-129, either through evaporation or through absorption by the tree leaves.
Given that the I-129 concentration has increased, however, the source of the increase is of interest. It's possible that the observed increase in concentration may be due merely to the amount of dilution water available, with less being available during drought conditions. Other possible mechanisms include increased leakage of I-129 from closed seepage basins, as well as a possible side effect of the phyto-remediation process.

Enhanced Tritium Monitoring (ETM) Program:
Due to public concerns over H-3 in the downstream drinking water, DNR's Augusta office participates in an enhanced H-3 monitoring program, which is designed to insure that H-3 concentrations in the Savannah River downstream at the US-301 bridge don't exceed a mutually-agreed-upon courtesy notification level (CNL) of 5,000 pCi/L. Samples are collected continuously from this location and tested (Table D-10-Sup.) for H-3 bi-weekly in the Augusta laboratory's liquid scintillation counter (Figure D-19 below). During the
Figure D-19 (A/B): Enhanced H-3 Testing Program for Downstream Water Users of the Savannah

(B) Testing River Water for H-3 With LS Counter

current 2000-2002 period none of the continuous samples from US-301 exceeded the CNL (Figure D-17 on previous page). However, periodic short-duration surges in H-3 concentration were detected. Short-duration surges are attributed primarily to batch releases from SRS's ETF facility and from VEGP. H-3 concentration data for US-301 (along with river flow information from USGS) were used to calculate total H-3 released per day into the Savannah River (Figure D-20 below).

Sediment:

Sediment samples (Table D-11) were collected at

least annually from up to 56 locations over a 190-

mile section of the Savannah River between

Augusta and the Atlantic Ocean near Savannah.

Samples were tested for gamma isotopic (Co-60,

Cs-137), Sr-89/90, and Pu-238/239. Several Site-

related radionuclides were detected in elevated quantities over a large section of the river during the current period (Figure D-21).

Area of Elevated Activity in

Cs-137 (a by-product of nuclear fission) was the

Sediment

most dose-significant, Site-related radionuclide

detected in elevated quantities (up to 540x

background adjacent to SRS and up to 190x

background downstream of SRS). Cs-137 is dose

significant due to its uptake and bioaccumulation

in aquatic plants and fish. SRS is believed to be

the primary source of the elevated Cs-137 in

sediment, given that it reportedly discharged over

600 Curies of Cs-137 to streams between 1954

and 1995 (WSRC-TR-970152), amounting to

more than 99.9% of all reported local discharges

of Cs-137. The area of heaviest contamination

(Figure D-22-A next page) is located adjacent to

SRS between Four Mile Creek (SRS), Steel Creek

(SRS), and Lower Three Runs Creek (SRS).

Contamination also extends over 100 miles

Figure D-21: Sediment Sample Locations

downstream of SRS to an area just upstream of

With Area of Elevated Activity

Savannah (near of I-95). Based on measured

isotopic ratios in sediment (Pu-238-to-Pu-239 used to differentiate local plutonium and Cs-137-to-Pu-239

used to differentiate local Cs-137), over 90% of the Cs-137 in the Savannah River appears to be of local

(SRS) origin (Figure D-22-B), with most of the remaining (~10%) probably due to global fallout.

Pu-238 and Pu-239, both of which were also reportedly discharged from SRS over the years (WSRC-TR970152), were also elevated (Figure D-23-A) in selected sediment samples collected adjacent to and up to 100 miles downstream of SRS. Based on measured isotopic ratios (of Pu-238 to Pu-239), it appears that the majority (approximately 50% to 100%) of plutonium detected near the main channel of the Savannah River may be associated with SRS discharges to Four Mile Creek (Figure D-23-B). Although somewhat elevated, plutonium in the Savannah River doesn't appear to have impacted the aquatic food chain or drinking water pathway to any measurable degree yet. Since the half-life of Pu-239 is so long (~ 24,000 years), possible future impacts be more significant, however.

Co-60 (up to 22x background) was detected in a number of sediment samples (Figure D-24) adjacent to and downstream of SRS and VEGP. Over the years, Co-60, a neutron-activated reactor by-product, apparently entered the Savannah River from at least four different effluent points: Beaver Dam Creek (SRS), Vogtle (VEGP), Four Mile Creek (SRS), and Steel Creek (SRS), based on a review of DNR's previous monitoring data. During the current 2000-2002 monitoring period, Co-60 was detected primarily at two of these effluent points: VEGP and Steel Creek (SRS). Given the half-life (~ 5.2 years) of Co-60, downstream sediment likely consists of a mixture of all four of these sources. Co-58 (a shorter-lived radioisotope of Cobalt) wasn't detected during the current period, suggesting no significant releases of newly activated Co-60.

Fish:
Several fish species (including largemouth bass, catfish, and panfish, such as bream) were collected at least annually from up to 11 locations over a 190-mile stretch of the Savannah River between Augusta and the Atlantic Ocean near Savannah. Samples were tested for H-3, gamma isotopic, Sr-89/90, and Pu-238/239 (Table D-13). H-3 was detected at elevated concentrations (up to 240x background) in many samples adjacent to and downstream of SRS. As previously noted, the majority (> 90%) of the H-3 is attributed to SRS, based on available effluent reports, with some (< 10%) attributable to VEGP. Cs-137 (Figure D-25-A) was also found to be elevated in many samples adjacent to SRS (up to 220x background), primarily due to contaminated SRS creeks and floodplains. Sr-90 was also found to be elevated (up to 5x background) in a few samples collected near Beaver Dam Creek (SRS) and Four-Mile Creek (SRS), and it is attributed primarily to underground seepage from closed radioactive waste treatment basins and burial grounds at SRS.
Although many samples contained elevated concentrations of radionuclides, most samples were below any significant risk-level of concern (Table D-13): 30-year excess-cancer-morbidity risk less than 10 out-of 1,000,000 for an average fish consumer (11 kg/yr). Largemouth bass near Steel Creek (SRS) was the exception, slightly exceeding these criteria by 30% for the 2000-2002 period, primarily due to Cs-137, as presented on the next page (Figure D-25-B). Current DNR consumption advice (one meal per week for largemouth bass from this area due to mercury) is already sufficient to cover any possible radiological concerns. Aquatic-pathway reporting levels (Figure D-25-C) were exceeded in three instances: catfish and panfish from Beaver Dam Creek (SRS) and catfish from Four-Mile Creek (SRS)

in deer samples (Table D-9). H-3 was slightly elevated (up to 3x background or detection limit) at

Screven Figure D-26: Average H-3 concentration in deer (pCi/kg fresh)

locations adjacent to SRS (Figure

D-26). This is most likely due to SRS releases of airborne H-3, since the majority (~ 99%) of local airborne

H-3 released is from SRS, based on available effluent reports. Elevated Cs-137 was also detected (up to 4x

the control value) in deer adjacent to SRS (Figure D-27). Based on this pattern, it appears that some of the

Cs-137 may also be SRS-related, but more study will be necessary to verify the source. SRS assumes that

deer migration from the Site is the primary mechanism contributing to SRS-related offsite-hunter doses.

It is unlikely that consumption of deer near SRS will pose a significant longterm radiological risk, but several years' worth of data will be needed to be sure of this. Pending completion of this task, a preliminary risk estimate was generated from the 2002 data. Cancermorbidity risk for consumption of deer containing Cs-137 near SRS is projected to be 7.8E-05 (or 78 out of 1,000,000), for an average hunter, over a 30-year period. This projection assumes an intake of 41 kg/year (per WSRC-RP-9117- p.21).
Possible site-related doses for deer consumption near SRS averaged 3.5 mRem/yr (23% of the reporting level), which compares favorably with SRS's dose estimate (2.9 mRem adjusted for average consumption) for offsite hunters (WSRC-TR-2000-00328, p.121).

Crops:
Several types of crops, including corn, peanuts, pears, and pecans, were collected from at least five locations, each, including a control or background location. Samples were tested for H-3, gamma-isotopic (including Cs-137 and naturally occurring K-40), Sr-89/90, and Pu238/239 (Table D-9). H-3 was the only radionuclide detected in any of these samples that is probably Site-related. The maximum annual dose associated with H-3 (in pears) is estimated to be less than 0.002 mRem (or 0.02% of the reporting level) for the 2000-2002 period, assuming annualaverage fruit consumption rates of 60 kg/yr (* WSRC-RP-91-17- p.21). Thus, the H-3 poses no significant risk. Trace levels of Sr-90 were also detected in several pear and pecan samples, but global fallout is likely to be the source, rather SRS, as comparable levels of Sr-90 were also detected in control samples (within statistical limits). Concentrations were sufficiently low in all samples to be below any level of concern. Maps of crop sample locations are presented below (Figures D-28), along with siterelated findings.

Milk:
Milk samples were collected from up to ten dairies monthly within a 50-mile radius of SRS and VEGP. Samples were tested for H-3, gamma-isotopic (including natural K-40, I-131, and Cs-137), and Sr-89/90. H-3 was the only radionuclide detected that was likely Site-related, and it was only detectable once (above the detection limit) at two of the ten locations monitored (Figure D-29). One location (# 210) where H-3 was detected (Feb-2002) is over 40 miles from any SRS/VEGP facility, which is somewhat unusual, in that H-3 wasn't detected in milk at closer dairies that month. This could have been caused by a localized H-3 rainout event, either into the area surrounding the dairy or into the Ogeechee River basin, upstream of the dairy (since this dairy is located on or near the Ogeechee River). Annual doses associated with H-3 were not significant (less than 0.002 mRem or 0.02% of the reporting level), and thus did not pose a significant risk.

Notes: (1) Highlighted results at two TLDs appear to be elevated relative to earlier trends, suggesting changes in the field exposure source. (2) TLD-1 is located at the I-20 Georgia Welcome Center in Augusta, and it is considered to be a control (background) location. Consequently, the exposure at TLD-1 is not due to any air-borne pathway from SRS or Vogtle. Instead, it may be transportation-related, given that a number of trucks stop there. (3) TLD-15 is located adjacent to the Savannah River at Brigham's Landing. Given that this TLD is designated as an indicator, the excess exposure could conceivably be related to SRS or VEGP operations, but that isn't likely, as all other TLDs in the area were normal. Instead, the excess exposure at this location may be be river-transportation-related, as barges occasionally transport larger items, such as reactor steam generators destined for burial at Barnwell, past this landing, prior to off-loading at SRS.

Notes: (a) Station (Sta) and Location (Loc) denote the location along the Savannah River where the fish were caught. (b) Fish Type denote the species grouping of fish, where:
Panfish include sunfish and bluegill Predators are large mouth bass or bowfin Bottom feeders are catfish or suckers Migratory are seafood or migratory fish, including shad, mullet, sea trout, shrimp, and blue crab. (c) Portion denote edible (filleted), inedible (bones, skin, digestive tract), or whole (both edible and inedible). (d) Radioisotope concentrations are the arithmetic average of individual analyses by location, fish type and portion. (e) Radioisotope and total excess cancer risk is the estimated contribution from observed radionuclide concentrations.

The USEPA has developed guidelines for assessing risk, primarily from chemicals found in hazardous waste sites. This guidance (see: Risk Assessment Guidance for Superfund, USEPA, December 1991 and Radiation Exposure and Risks Assessment Manual, USEPA, June 1996) considers two general categories of risk to human health-carcinogenic and noncarcinogenic risk. When considering exposure to radioactive materials, carcinogenic risk is considered for most radionuclides. EPA recommends an approach for evaluating radiation-induced cancer risks that is calculated as the product of the estimated lifetime intake or external exposure for a particular contaminant times a measure of the likelihood of incremental cancer induction per unit exposure for that contaminant, termed a slope factor. The slope factor is an estimate of the probability of a response (that is, the probability of an individual developing cancer per unit of intake or exposure to a carcinogen over a lifetime). Radionuclide slope factors are central estimates of the age-averaged lifetime cancer incidence risk per unit inhaled, ingested or exposed. Tables of slope factors have been compiled by EPA and can be found in EPA's Integrated Risk Information System or published in Health Effects Assessment Summary Tables, USEPA, 2001.

To calculate the risk of eating radionuclide contaminated fish taken from the Savannah River, EPD uses the following equation:

Riski,ing = SFi,ing Ci,ing IRi,ing EF ED AF

where, Riski,ing SFi,ing Ci,ing IRi,ing EF ED AF

= Lifetime excess cancer risk from radionuclide i and pathway ingestion = Slope factor for radionuclide i and pathway ingestion (risk/pCi ingested) = Concentration of radionuclide i in the contaminated food (pCi/g) = Ingestion Rate (g/day) = Exposure Frequency (days/year) = Exposure Duration (years) = Adjustment factor for site-specific conditions (no units)

Slope Factors used:

SF = 3.7410-11 risk/pCi (also expressed as 3.74E-11)

H-3

SF = 6.5110-14 risk/pCi (also expressed as 6.51E-14)

Sr-90

SF = 9.5310-11 risk/pCi (also expressed as 9.53E-11) [Note: Short-lived Decay risk included]

Section E - Edwin I. Hatch Nuclear Plant

Georgia Power Company's Edwin I. Hatch Nuclear Plant (Figure E-1) is a two-unit Boiling Water Reactor (BWR) facility located on the Altamaha River in Appling County, Georgia, adjacent to Toombs County. This facility, which was supplied by the General Electric Company and which is operated by Southern Nuclear Operating Company, has been in operation since 1975.

The Georgia Department of Natural Resources has

monitored Plant Hatch since 1978, during which period

Site-related radionuclides were generally non-

detectable in most off-site samples, with the exception

Figure E-1: Plant Edwin I. Hatch

of downstream river sediment. Site-related, low-level

Co-60 and Mn-54 have been routinely detected in sediment. Site-related Cs-134 and Cs-137 were also

detected in sediment following a 1986 spill of water from the spent fuel pool. Global fallout-related

radionuclides (Nb-95, Zr-95, Ru-103, Ru-106, Ce-141, Ce-144, and Cs-137) were also detected one year

(1981) during the Chinese weapons testing period. Chernobyl-related fallout radionuclides (I-131, Cs-

134, Cs-137, Ru-103, and Ru-106) were detected another year (1986). During the current 2000-2002

period, Co-60 and Mn-54 (up to 6x Bkg.) in river sediment were the only Site-related radionuclides

detected above background levels. Maps detailing all locations monitored are provided in Figure E-3

(locations on land) and Figure E-4 (locations on water) on subsequent pages.

Direct Radiation (TLDs): Direct radiation doses, as measured by TLDs (Thermo-Luminescent Dosimeters - Table E-1) were within the normal (expected) range, with indicator locations (near Plant Hatch) measuring slightly less than background (or control) locations (Figure E-2). This is probably due to the difference in construction of roads, near which TLDs are located. Dose rates near paved roads tend to be

higher, due to naturally occurring radionuclides often found in some road bed materials (such as concrete and gravel). Dose rates along un-paved roads, such as those near the river and closer to the Plant, tend to be lower. Based on a review of the soil sample results, naturally occurring radionuclides in the Uranium, Thorium, and Potassium series appear to account for over 99% of the direct radiation dose recorded on the TLDs. One anomalous (low) reading was recorded on TLD # 24 (located approximately 4 miles west of the Plant) for the period ending 10/13/2000. No Site-related dose readings were detectable or distinguishable from background, based on the available data.

Air Samples: Air samples results (Table E-2) were also within the normal (expected) range, with similar results observed for indicator and background locations, including seasonal variability in the beta results (Figure E-5). Naturally occurring Pb-210, a long-lived radon daughter, is the believed to be the primary source of beta activity routinely detected. (Pb-210 results were found to be comparable to beta results, when tested, but Pb-210 isn't routinely tested, as it requires use of a specialized low-energy detector). Naturally occurring Be-7, which is formed from cosmic-ray interactions in the atmosphere, was the only gamma-emitting nuclide routinely detected. No Plant-related radionuclides were detected.

Soil Samples: Soil sample results (Table E-3) were within the normal range and generally comparable for background and indicator locations, with no detectable radionuclide activity attributable to Plant operations. Cs-137 was the only man-made radionuclide detected, but it was attributed primarily to global fallout rather than Plant operations, since indicator and background samples had comparable concentrations of Cs-137 (Figure E-6 next page). Naturally occurring radionuclides (Ra-226, Ra-228, K40, and progeny) were also detected and accounted for most of the activity in the samples.

Georgia Environmental Radiation Surveillance Report 2000 2002
Section E Plant Edwin I. Hatch E-5

Vegetation: Vegetation samples (Table E-5) were also within the normal (expected) range, with global fallout-related Cs-137 detected in several samples. No distinguishable man-made activity attributable to Plant operations was detected. Naturally occurring Be-7 and K-40 were also found in most samples. Concentrations of Cs-137 in indicator samples were comparable to that found in the background or control samples (Figure E-6) for both vegetation and soil.

Ground Water: Ground water results (Table E-4) were within the normal range, with no detectable manmade activity. Low levels of alpha and beta activity were detected in some samples, including the background sample, which is attributed to naturally occurring radionuclides, such as Ra-226 and Ra-228. Beta results for indicator locations were generally comparable to background beta results (within the statistical bounds of the background).
Milk: No man-made radionuclides were detectable (< 1 pCi/L for Cs-137) in milk samples (Table E-6) collected near Plant Hatch. Naturally occurring K-40, which is a part of natural potassium, was detected in all samples within the normal range.
Surface (River) Water: No Site-related activity was detected in any river water samples (Table E-7), which were tested for alpha, beta, gamma-isotopic, and H-3. Average beta results were slightly higher but not statistically significant downstream, with a net difference of 0.1 + 1.6 pCi/L.

Section E Plant Edwin I. Hatch E-6

River Sediment: As noted on page E-1, Co-60 and Mn-54 in river sediment (Table E-8) were the only Site-related radionuclides detected above background during this period. Downstream concentrations of these radionuclides (Figure E-7) ranged between 1.5 and 6.5 times the control value (or the detection limit value) between Plant Hatch and Jesup, Georgia (approximately 50 miles downstream). No Site related radionuclides were detected in the Coastal area (US-17 near Darien). Cs-137 in the Coastal area, which was found to be higher than at the freshwater background location, was within the normal (background) range for the saltwater-transition zone control location (Ogeechee River). Concentrations of Site-related Co-60 and Mn-54 in sediment were insignificant and did not result in any detectable activity in dose-significant pathways to humans, including fish and drinking water.

Fish and Seafood: Fish: No radionuclides that could definitely be linked to Site operations were detected in any fish or seafood samples. Freshwater fish samples (Table E-9) contained naturally occurring K-40 and low levels of Cs-137, which is a man-made radionuclide primarily related to global fallout. Saltwater fish and seafood samples (Table E-8) only contained naturally occurring K-40. Concentrations of Cs-137 in freshwater fish in the coastal area (near I-95) were slightly higher (but not statistically significant) than at other Hatch monitoring locations (Figure E-8). This mirrors a similar finding for sediment, wherein higher Cs-137 concentrations also occurred in the coastal area. Thus the two Cs-137 findings are likely to be interrelated through global fallout, as noted in the review of the sediment data above. Since the error bars for the freshwater fish data (control and coastal indicator) overlap, the differences are not statistically significant, in any case. From a radiological risk perspective for cancer morbidity, the Cs-137 concentrations aren't significant either (less than or equal to 4.0E-07 or four-out-of-ten-million, which is well below any fish advisory guide).

Notes: (1) Highlighted results are slightly elevated above background and are attributed to operations. (2) Cs-137 concentrations in the Altamaha coastal area (station # 360), although higher than in the upstream control location (# 300), are within the normal range of the coastal control location (# 740) on the Ogeechee River. Therefore, it is likely that the Cs-137 at station # 360 is related to global fallout rather than operations at Plant Hatch.

Section F - Joseph M. Farley Nuclear Plant

Alabama Power Company Joseph M. Farley Nuclear Plant is a two unit Pressurized Water Reactor (PWR) facility located on the Chathoochee River in Houston County, Alabama, adjacent to Early County, Georgia. This facility, which was supplied by the Westinghouse Corporation, and which is operated by Southern Nuclear Operating Company, has been in operation since 1977.

The Georgia Department of Natural Resources

(DNR) has monitored Plant Farley since

approximately 1978, with low-level Co-60 in river

sediment and low-level H-3 in river water being the

only Site-related radionuclides detected. However,

several global fallout-related radionuclides

(including Nb-95, Zr-95, Ru-103, Ru-106, Ce-141,

Figure F-1 (Plant Farley)

Ce-144, and Cs-137) were also detected one year

(1981) during the Chinese weapons testing period. Cs-137 is the only one of these nuclides that is still

detectable. During the current 2000-2002 period, H-3 in river water and Co-60 in river sediment were the

only site-related radionuclides detected. Maps detailing the locations monitored are provided in Figure F-3

(locations on land) and Figure F-4 (locations on water) on subsequent pages.

H-3 (up to 23x Bkg.) which was detected in several downstream river-water grab samples (Figure F-2 and Table F-6) during the current period is attributed to Plant operations. (H-3 is a non-filterable, water-borne byproduct often formed in PWR reactors as a result of neutron interactions with boron). Downstream H-3 concentrations averaged 1,100 pCi/L (detectable results only) during the current monitoring period, which is equivalent to less than 6 % of the Safe Drinking Water MCL. Concentrations of H-3 in the Chattahoochee River were somewhat higher during this period compared to previous periods, possibly due to lower river-water flow, which provided less dilution.

River Sediment: As noted earlier, Co-60 in river sediment (Table F-7) was the only other site-related radionuclide detected (up to 2x Bkg) during the current monitoring period. Naturally occurring radionuclides from the Uranium (Ra-226), Thorium (Ra-228), and Potassium (K-40) series were also detected, along with a trace of Cs-137, which is primarily related to global fallout. Concentrations of Co-60 in sediment were insignificant (just above the detection limit) and did not result in any detectable activity in dose-significant pathways to humans, including fish and drinking water.
Direct Radiation (TLDs): Direct radiation doses, as measured by TLDs (Thermo-Luminescent Dosimeters Table F-1) were within the normal (expected) range, with indicator locations (near Plant Farley) measuring slightly less than background (or control) locations (Figure F-5). This is probably due to the difference in construction of roads, along which TLDs are located. Dose rates near paved roads tend to be higher, due to naturally occurring radionuclides often found in some road bed materials (such as concrete and gravel). Dose rates along un-paved roads, such as those near the river and closer to the Plant, tend to be lower. Based on a review of the soil samples results, naturally occurring radionuclides in the Uranium, Thorium, and Potassium series appear to account for over 99% of the direct radiation dose recorded on the TLDs. Indicator and background locations show similar seasonal variability, which is typically caused by seasonal variability in naturally occurring airborne radon.

Section F Plant Joseph M. Farley F-4

Air Samples: Air samples results (Table F-2) were also within the normal (expected) range, with similar results observed for the indicator and background locations. Comparable seasonal variability (for the beta portion of the results) is also noted for both locations (indicator and background), as illustrated in Figure F6. This is assumed to be due to variability in the airborne concentration of the long-lived radon daughter Pb210. Naturally occurring Be-7, which is formed from cosmic-ray interactions in the atmosphere, is the only gamma emitting nuclide that was detected. (Pb-210, which was detected in some samples and found to be comparable to the beta results, isn't reported here, as it wasn't tested in all samples, since it requires use of a specialized low-energy detector).

Soil Samples: Soil sample results (Table F-3) were normal and generally comparable for background and indicator locations, with no detectable radionuclide activity attributable to Plant operations. Cs-137 was the only manmade radionuclide detected, but it was attributed to global fallout rather than Plant operations, since background concentrations were comparable to indicator concentrations. Naturally occurring radionuclides (Ra-226, Ra-228, K-40, and progeny) were also detected and accounted for most of the activity in the samples. Higher levels of naturally occurring K-40 were detected in soil samples taken near the river
Ground Water: Ground water results (Table F-4) were normal, with no detectable man-made activity. Low levels of alpha and beta activity were detected in some samples, including the background sample, which is attributed to naturally occurring radionuclides, such as Ra-226 and Ra-228.

Georgia Environmental Radiation Surveillance Report 2000 2002
Section F Plant Joseph M. Farley F-5

Vegetation: Vegetation samples (Table F-5) were also normal, except possibly for one sample, with no man-made activity attributable to Plant operations. Naturally occurring Be-7 and K-40 were found in most samples. Global fallout-related Cs-137 was non-detectable in all samples, except for one sample, which was collected approximately 3 miles east of the Plant near the end of 1999. This sample contained Cs-137 at a concentration that was approximately eight times the detection limit, which makes this result somewhat unusual for the sample group. Cs-137 uptake in vegetation can be quite variable from one plant species to another and from one soil type to another. The most likely explanation for the unusual result is believed to be selection of a different plant species, which is sometimes done by the field crew, if the primary vegetation type isn't available.
Fish: Fish samples (Table F-8) contained naturally occurring K-40 and low levels of Cs-137, which is a man-made radionuclide primarily related to global fallout. Concentrations of Cs-137 were slightly higher, but more variable, downstream (in Lake Seminole), than for other locations (Figure F-7). However the high variability for this location suggest the possibility that the data may be comparable to the background location, since the error bars overlap. Thus the slightly higher downstream concentration isn't considered to be statistically significant. Also, the concentration isn't significant from a risk perspective either: < 4.0E-07 or less than one out of one million ... well below DNR's guide (1.0E-05).

Note: Highlighted H-3 results, which are slightly elevated, are likely due to Plant operations. H-3 is a non-filterable, water-borne byproduct formed in PWR reactors as a result of neutron interactions with boron. H-3 results averaged less than 6% of the Safe Drinking Water MCL based on the available data.

Section G Naval Submarine Base, Kings Bay

Naval Submarine Base, Kings Bay supports the Trident Nuclear Submarines and their associated ballistic missile systems, as a part of the U.S. Navy's Fleet Ballistic Missile Submarine facilities. Kings Bay also supports other classes of submarines. It is situated between St. Mary's, Georgia on the West and Cumberland Sound on the East, in Camden County. Submarine wharves, dry-docks, and other support facilities are located on the waterfronts of Kings Bay and Cumberland Sound.

The Georgia Department of Natural Resources

(DNR) has monitored Kings Bay since it started

operations in 1978. During this period, no

measurable radioactivity that could be attributed to operations at the Base has been detected by DNR.

Figure G-1: Kings Bay Water-Front

Only naturally occurring radionuclides and global

fall-out-related Cs-137 have been detected in the environment around King's Bay. Monitoring location

maps are provided in Figure G-3 (land-based monitoring) and in Figure G-4 (aquatic monitoring) on the

next two pages.

Direct Radiation: During the current monitoring period (2000-2002), all TLD dose-rate measurements (Table G-1) were normal with the possible exception of one elevated reading (Figure G-2) at a background location (intersection of I-95 and I-16 near Savannah). Since this TLD is located over 80 miles from Kings Bay, the anomalous reading wasn't related to operations at Kings Bay.

Instead, the TLD anomaly could conceivably be transportation-related, since the TLD is located at the intersection two busy freeways. It could also be construction-related, since highway and bridge maintenance occasionally requires the use of radiographic cameras and gauges. In any case, the activity wasn't related to Kings Bay, and the total dose involved was very small: less than 4 mrem total and less than 20% elevated over the normal background reading for the Quarter.
As previously noted, no other unusual results were observed on any other TLDs. Overall, background readings were higher than indicator readings (Figure G-5), indicating no measurable off-site doses due to operations at Kings Bay. (Higher background readings are attributed to their location near paved highways and developed areas). Naturally occurring radionuclides and their progeny (including the Uranium (Ra-226), Thorium (Ra-228), and Potassium (K-40) series) appear to account for more than 99% of the observed doses.
During the current monitoring period, some changes were made in DNR's TLD locations after September 11, 2001 (911), due to access and security concerns at Kings Bay. All TLD stations on Crab Island (which is between the Kings Bay waterfront and Cumberland Sound) were discontinued after 911. Since Crab Island TLDs were all very low in natural radioactivity (due to the sandy environment), their discontinuance resulted in an increase in the overall (average) indicator dose rate. Therefore, two indicator dose rate trends were established for future reference: Pre-911 and Post-911 trends.

Note: All Crab Island Indicator TLD stations were discontinued after 911, due to access and security 20 concerns. In addition, boat and weather problems prevented the retrieval of other island-based TLDs.
This resulted in a change (increase) in the Pre-911-Indicator dose rate trend, as most of the island stations are very low in natural radiation, due to the island's primary soil type (sand). Therefore, a Post-911-Indicator trend is also presented above.

Soil: Soil sample results (Table G-2) were normal, with no unexpected findings. The only man-made radionuclide detected was Cs-137, which is attributed primarily to global fallout. Naturally occurring radionuclides (including Ra-226, Ra-228, and K-40) accounted for the majority of the activity detected. Cs-137 activity did show some interesting patterns (Figure G-6), however. Since the background sample (Station # 18 which is located 18 miles away) had the second highest level of Cs-137, Site operations don't appear to have contributed any measurable Cs-137activity to indicator locations. In fact, the closest indicator location (Station # 23 on Crab Island less than 1 mile from operations) had the lowest activity, which seems to support this finding. However, this location has received dredged fill material over the years, so that the current top layer of soil (or sand) might not be reflective of what was deposited by global fallout from previous years.

Groundwater: Groundwater results (Table G-3) were normal, with no detectable man-made radionuclides. Very low levels of beta activity, which are most likely due to naturally occurring Ra-228 and K-40, were detected in most samples. No site-related activity was detected.

Vegetation: Vegetation results (Table G-4) were normal (within the expected range) and show somewhat similar Cs-137 patterns (Figure G-7) as that observed in the soil samples. The background location had the highest level of Cs-137, which suggests that the Cs-137 is not site-related. Naturally occurring Be-7 and K-40 were also detected.

Surface Water: Surface Water results (Table G-5) were within the normal (expected) range, with no detectable activity that could be attributed to Site operations. No man-made gamma-emitting radionuclides were detected. However, significant levels of beta activity were detected, due primarily to naturally occurring K-40 in seawater, which can be detected by gamma analysis (Figure G-8). These levels are normal for seawater, which contains a variety of dissolved mineral salts, including KCl.

Fish and Seafood: No man-made radionuclides were detectable in fish and seafood samples (Table G-6). Naturally occurring K-40 was the only radionuclide detected. K-40 is found in all living organisms at similar concentrations, as it is present as a long-lived radioisotope of potassium, along with nonradioactive potassium, which is necessary for life.

Sediment: Results for sediment samples (Table G-7) were within the normal (expected) range, with no man-made radionuclides detected except for Cs-137. The Cs-137 is attributed primarily to global fallout, since the background location contained more Cs-137 than indicator locations (Figure G-9).

Note: The highlighted result is considered slightly elevated from the normal dose rate for this location. Since this is a background location (located at the intersection of I-95 and I-16 near Savannah), it is not related to operations at Kings Bay. However, it may be transportation-related, since it is in a heavily traveled corridor. It should also be noted that the uncertainty of this measurement was higher than normal, which could indicate a possible problem with the dosimeter rather than an actual elevated dose.

Note: Cs-137, a product of global fallout, appears to be higher in vegetation growing in sandy, nutrient-poor soils near the ocean. Crab Island, which is the closest island to Kings Bay, appears to be an exception, in that no Cs-137 was detected. This may be due to the dredged fill material, which has

been used to build up the island, or it may be due to the proximity of the vegetation to the salt-water

zone, which may improve uptake of potassium, which competes with cesium in uptake by plants.

Section H Georgia Tech Research Reactor (GTRR) - Decommissioned

The recently-decommissioned Georgia Tech Research Reactor (GTRR), which is located at the Frank H. Neely Nuclear Research Center on the Georgia Tech Campus in Atlanta, Georgia, was a 5-Megawatt, highly enriched, heavy water moderated research reactor (Figure H-1). Prior to the 1996 Olympics, it was permanently shut down and de-fueled in preparation for it's decommissioning, which is now complete.

During the period that GTRR was operational and

monitored by Ga-DNR (1978-1995), the only

routinely detectable radionuclides that could be

attributed to GTRR operations were H-3, Co-60,

Cs-137, and gross beta in wastewater from a

liquid-waste hold-up tank. Site-related direct

radiation (attributable to gamma-shine from radioactive materials and wastes stored in an auxiliary building near the SE corner of the site)

Figure H-1: Georgia Tech Research Reactor, With Adjacent Auxiliary Building in SE Corner of Site

was also detected on a nearby dosimeter over a 20-year period. Global-fallout-related radionuclides

(including Nb-95, Zr-95, and Cs-137) were also detected, including fresh deposits during 1981 after a

series of Chinese weapons tests. Of these radionuclides, Cs-137 is the only global-fallout-related

radionuclide still detectable.

During the current 2000-2002 period, which involved demolition and decommissioning (D&D), elevated direct (gamma) radiation and slightly-elevated concentrations of H-3 and Co-60 (in some samples) were periodically detected off-site (near the fence-line). Measurable direct radiation and environmental radioactivity from D&D appears to have been confined to the immediate area (within approximately 100
feet of the fence-line), with no significant offsite doses in excess of 10CFR20.1301-1302 regulatory limits. Offsite doses from all monitored pathways approached (81 mRem) but didn't exceed the annual dose limit (100 mRem) in one area (west fence-line), between April-2000 and April-2001. However, reporting levels were exceeded along the south and west fence-lines during this period.

Figure H-2: View Toward GTRR West Fence-Line Showing Radioactive Waste Shipment (Reactor Vessel in Cask) and Adjacent Office Trailers Outside the Fence (Photo Courtesy of Ga-Tech)

This off-site area (outside of west fence-line) was also the location of the critical offsite population (construction workers), as it contained office trailers used during the construction of a nearby parking deck. Radioactive waste shipments (Figure H-2) from GTRR were also temporally stored and shipped from an adjacent area just inside of the west GTRR fence-line, which is why this area received the highest dose. A map of the GTRR area, including monitoring locations, is provided in Figure H-3 on the next page.

Georgia Environmental Radiation Surveillance Report 2000 2002
Section H Georgia Tech Research Reactor H-2

Direct gamma radiation shine (~ 80 mRem) coming from inside of the west fence-line contributed most of the off-site dose (> 98%) in this area. In addition to direct radiation, a small amount of airborne H-3 was detected during D&D, with doses estimated to be less than 0.002 mRem. Co-60 was also detected on vegetation and soil samples collected near the Northwest fence-line on one occasion, suggesting either a possible localized airborne release or a surface-water-borne release of Co-60. Assuming a conservative particle size (100% respirable) and deposition rate (0.1 cm/s), the maximum fence-line dose from an airborne Co-60 release would have been approximately 0.01 mRem (effective) and 0.07 mRem to the lungs). Consequently, doses for all monitored pathways were still less than 81 mRem in a one-year period in the area of highest dose. The annual dose to a real individual working in this area was likely to be less (~ 20 mRem), however, based on a 40-hour workweek.
Direct Radiation TLDs (Details):
Thermo-Luminescent Dosimeters (TLDs) were collected to monitor direct radiation quarterly (Table H1-A) and monthly (Table H-1-B) near GTRR. A total of 21 TLD locations were monitored at the start of D&D, but several of these locations were discontinued during the 2000-2002 period, due to new construction on the Georgia Tech campus. Monthly TLDs were utilized mainly during D&D around the fence-line, in order to get frequent, high-resolution, off-site dose information. Quarterly TLDs, which had been in place for a number of years during GTRR's operation, continued to be monitored, where already established. TLD data were used to determine D&D-related direct-radiation doses (Figure H-4), including maximum-annual dose and total D&D dose, by time-integration of TLD dose-rates minus background (pre-post baseline) dose-rate (Figure H-5). Dose rates varied considerably during D&D, depending on the TLD location and on the particular D&D activity occurring during a particular period.

Dose rates were also monitored continuously via a real-time, telemetered, gamma-radiation monitor, which was located on the south fence-line adjacent to the air and precipitation sampler (Figure H-6). This instrument provided dose-rate information every 5 minutes, and it was set-up to send a remote alarm, in the event of higher-than-expected radiation levels. Dose-rate information from this instrument (Figure H-8) made it is possible to distinguish different phases of the D&D work. It was also useful for ALARA (As-Low-As-Reasonably-Achievable) purposes during D&D, since it provided instantaneous off-site feedback to the process.

Based on a review of the real-time data, the highest instantaneous dose rates were associated with removal of the reactor vessel (~28 micro-Rem per

hour averaged over an 8-Hr day) and removal of the graphite (~ 40 micro-Rem per hour averaged over an

8-hour day). Removal of the steel jacket and the lead thermal shield resulted in the longest-continuous

elevated dose-readings, however. This instrument was also able to detect and monitor another nearby

radiological influence (radiography of an adjacent parking deck), which wasn't related to D&D, but

which potentially contributed some dose.

fence-line of GTRR. Radionuclides that were initially tested included alpha, beta, and gamma-isotopic (Fe-55, Co-60, Cs-137, Eu-152, Pb-210, etc.) on air filters, as well as I-129, which was tested on charcoal-based collection media (Table H-2-A). H-3 was added (Table H-2-B) immediately after a small airborne H-3 release was reported during D&D (February 2000). H-3 was the only man-made, site-related radionuclide detected in sir during D&D. Beta, Pb-210 (natural) and Be-7 (natural) were also routinely detected. Naturally occurring Pb-210 accounted for most of the beta activity. Air sample trends for H-3, beta, and Pb-210 are presented below (Figure H-7).

Calculated doses (0.002 mRem in one year) due to D&D-related airborne H-3 were a minor part (~0.002%) of the total D&D-related dose (up to 81 mRem). This dose is typically what would be received in less than 15 minutes from naturally occurring direct radiation at the control or background TLD location. (The direction-radiation dose rate measured at the control location (TLD-8) was 82 mRem per year or 0.009 mRem per hour at the end of this report period). H-3 was detected primarily in association with the opening and cutting of pipes and the removal of the reactor vessel.
Precipitation: Precipitation samples (Table H-3) were also continuously collected from the southeast corner of GTRR just outside of the fence. Samples were tested for alpha, beta, H-3, and gamma-isotopic radionuclides. No man-made radionuclides were detectable or attributable to D&D. Trace levels of beta emitters were detected and attributed to Pb-210, as was also the case for air filters.
Surface Run-Off Water: A run-off water collector (55-gallon drum) continuously received portions of any water that ran off of the concrete pad inside the GTRR fence-line. Run-off water from this area flowed into a nearby storm-sewer portal. H-3 was the only D&D-related radionuclide detected (Table H4), with positive results detectable for only a two-month period (February-March 2000), during which time pipe cutting and pipe-removal operations were occurring. Results averaged 300 pCi/l (or 2% of the Drinking Water MCL) during this period.
Suspect Waste-Water: During the operation of GTRR, suspect waste water was collected and held in a tank for acceptance testing, prior to discharge into the sewer. This tank was removed early during the D&D process. Consequently, samples were no longer collected after February 2000. H-3, which was the only Site-related radionuclide detected increased sharply in the last sample (February 2000) due to D&Drelated pipe cutting and pipe-removal operations. This mirrored similar changes noted in H-3 in run-off water and H-3 in air. The highest concentration of H-3 detected was 215,000 pCi/L (< MPC limit for sewer discharge), prior to dilution and discharge to the sewer.
Vegetation and Soil: Vegetation samples (Table H-6) and soil samples (Table H-7) were collected from five locations (including one control location) during D&D. H-3 and Co-60 were the only D&D or Siterelated radionuclides detected in vegetation. Co-60 was the only D&D or Site-related radionuclide detected in soil. Naturally occurring radionuclides were also detected in vegetation (Be-7 and K-40) and soil (K-40, Ra-226, and Ra-228). D&D-related H-3 was detected on the south and southwest side of GTRR in vegetation near the fence-line in February 2000 after the small airborne H-3 release, which was reported. Measured H-3 concentrations in vegetation from this area did not exceed 600 pCi/L (of free water in the vegetation). This is equivalent to 3% of the Drinking Water MCL, to put it into perspective.
In addition to H-3, Co-60 was also detected (180 pCi/kg fresh weight) in vegetation on one occasion on the northwest side of GTRR near the fence-line. Co-60 was also detected once in a soil sample (88 pCi/kg dry weight) from the west side of the GTRR fence-line. This material could have been deposited in soil and vegetation through a localized airborne release, or it could have been deposited through run-off water. Co-60 wasn't detected in run-off water, but it's possible that it could have been present below the detection limit, and that it could have accumulated in the vegetative mat. Co-60 also wasn't detected in air samples, but it could have been released when the wind was blowing in a different direction. Deposition via a possible airborne-release pathway presents the most conservative dose potential. As previously noted (page H-3), any associated air-pathway dose for Co-60 detected in the vegetation and soil would have been no more than 0.01 mRem (effective) and 0.07 mRem (to the lungs), which is approximately 0.01% of the total measured D&D dose on the western side of GTRR. A combined trend-plot for H-3 in vegetation and run-off water, and Co-60 in soil and vegetation, is presented on the next page (Figure H9)

In-Situ Gamma Scans: In-situ gamma-spectrometry scans (Table H-8) were conducted primarily around the old GTRR parking lot area on the north side of GTRR, prior to it's demolition and removal. This area was the site of the new parking deck, which was also constructed during the D&D period. It-situ scanning was the quickest and most cost-effective method to characterize this area, since it consisted of a mixture of materials (soil, pavement, concrete, etc.). Based on this characterization, it was determined that no siterelated gamma-emitting radionuclides were present, and that naturally occurring radionuclides accounted for most (> 99.5%) of the direct radiation doses in this area. Fallout-related Cs-137 accounted for a small portion (up to 0.5%) of the dose, as well. Co-60 was detected in one scan taken near the southeast corner, but the material detected was actually inside of the fence-line in a radioactive-waste container. In this instance, the Co-60 contributed approximately 3% of the measured direct radiation dose.

Notes: (1) In-situ gamma scans were performed to characterize the area just prior removal and grading of the old parking lot and adjacent areas on the north side of GTRR, in preparation for new parking deck construction. (2) Higher dose rates over paved areas are attributed primarily to naturally occurring radionuclides from the K, Th, and U decay chains in structural materials, such as concrete and gravel. (3) Highlighted Co-60, which was detected near the SE corner of the GTRR fence-line, was attributed primarily to gamma shine from a radioactive waste-storage area and waste container inside of the fence-line. Co-60 was not detected in any individual soil samples from this location (TLD # 9), indicating that the area was clean.

Section I Dawson Forest Wildlife Management Area (2000-2002)
(Formerly the Georgia Nuclear Aircraft Laboratory GNAL)
Figure I-1: Monitoring for Gamma Radiation Outside of the Hot Cell Building at DFWMA
Dawson Forest Wildlife Management Area (DFWMA) is a 10,000-acre tract of land located in Dawson County, approximately 5 miles southwest of Dawsonville, Georgia. It is the decommissioned site of the former Georgia Nuclear Aircraft Laboratory (GNAL), which was operated by Lockheed Aircraft Corporation, under contract for the U.S. Air Force, until it was decommissioned around the end of 1971. Facilities containing radioactive materials at GNAL included a test reactor, hot cell building (Figure I-1), seepage basins, and cooling-off area (for temporary outdoor storage of "hot" items after irradiation at the reactor site). The land, which is now owned by the City of Atlanta as a possible future airport site, is currently managed by the Georgia Forestry Commission for the purpose of forestry management and by the Georgia Department of Natural Resources for the purpose of game management. Ga-DNR first initiated environmental monitoring of DFWMA shortly after their Environmental Radiation Program was formed at the end of 1977. At that time, a portion of the Site was found to contain residual activity of possible concern, including the cooling-off area, reactor area, and the inside of the hot cell building. These locations are detailed in the monitoring map (Figure I-2) on the next page. The cooling-off area and the hot cell building were subsequently fenced-in to prevent public access. Entrances to the hot cell building and to reactor-area structures were also sealed off to prevent intrusion, due to physical safety concerns and radiological concerns. Fences weren't deemed necessary at the reactor site, however, since the concentration of radioactive material, which was formed through reactor-generated neutron activation of soil, was lower and more diffuse, as compared to the hot spots found inside of the cooling-off area and inside of the hot cell building. During the past 25 years, DNR has continued to monitor DFWMA, in order to insure that any residual radioactivity of possible concern remained confined within the fenced-in areas and sealed structures. Due to the relatively long-lived nature of residual radionuclides detected in some areas of DFWMA and due to physical safety concerns, radiological monitoring and the use of fences and barriers to restrict public access will likely continue until such time as there is a need to change the property's usage.

External Radiation Dosimetry Measurements and Results
DNR has conducted quarterly or semi-annual direct (external) gamma radiation measurements in public-accessible locations at DFWMA since approximately 1979. A variety of instruments have been used for this task, including hand-held dose-rate monitors, a gamma spectrometer (Figure I-1), and TLDs (Thermo-Luminescent Dosimeters - Figure I-3). TLDs were the primary means used by DNR for continuous long-term dose monitoring. Gamma spectrometry was used primarily to determine the relative contribution of each radionuclide (including naturally occurring nuclides) to gamma doses. Handheld instruments were used primarily to survey the perimeter to insure that hotspots remained confined.

Direct radiation dose rates, as recorded by the TLDs, have

declined noticeably, during the past 25 years, in two areas (reactor area Figure I-4 and cooling-off area Figure I-5). This is not surprising, given that the majority of man-made

Figure I-3: TLD Dosimeters Attached to Pole

radioactivity at the start of DNR's monitoring was determined to be site-related Co-60, which has a half-life

of approximately 5.3 years. Dose rates in the third area (Hot Cell Area Figure I-6) haven't changed

noticeably, as the monitored area (outside of the hot cell building) doesn't appear to contain any detectable

site-generated radionuclides. Doses at all TLD locations currently appear to be nearing background levels.

I-4

As illustrated in Figure I-4, radiation levels in the cooling-off area were initially higher than in any other area monitored by TLDs. This was the primary reason that the cooling-off area was fenced-in, to minimize any possible dose to the public. Elevated dose rates in this area were due entirely to Co-60 hot-spot activity, which was found to be present inside of the perimeter of this area. Hot-spot activity in this area is believed to be due to a tornado, which scattered a drum of waste materials over several acres of this area. Initial dose rates in the reactor area, while also elevated, were significantly lower than in the cooling-off area, as illustrated in Figure I-5. Elevated gamma dose rates in this area were determined to be due primarily to two radionuclides: Co-60 and Eu-152. These radionuclides were produced primarily through direct, reactorgenerated, neutron activation of soil, rocks, and reactor-building components (concrete and steel). Due to the neutron-activated nature of the activity in this area, radionuclide concentrations are more uniform and diffuse, than in the cooling-off area As illustrated in Figure I-6, dose rates outside of the hot cell building haven't changed significantly (compared to background) over the past 25 years that DNR has monitored this area. Dose rates in this area, while higher than at the background location, are attributed almost entirely to naturally occurring radionuclides in the concrete hot cell structure, based on field gamma spectrometry and soil sample data. During the current monitoring period (CY-2000-2002), TLD gamma dose rates were found to be within the expected range, based on previous results, and they are nearing background levels. However site-related man-made radioactivity still accounts for up to for 15% of the dose in some areas, as illustrated in Figure I7. Given that TLDs are used only to monitor public-accessible areas, no conclusions could be drawn from the data regarding current doses and activity levels in restricted areas (inside of hot cell, inside of reactor structure, and inside of cooling-off area fence-line). Individual TLD dosimeter results are presented in Table I-1 (next page).

Soil Sample (In-Lab) and Field Gamma Spectrometry Measurements

Soil samples were collected from several locations near designated TLD stations. These samples were analyzed for gamma-emitting radionuclides. Field (in-situ) gamma spectrometer measurements (reference Figure I-1) were also acquired from several locations where concrete structures were located, since portions of these structures couldn't be easily removed for in-lab analysis. As discussed in the direct radiation (TLD) section, above, Co-60 (up to 11x Bkg) and Eu-152 (up to 26x Bkg) were the only detected nuclides that were definitely attributed to site operations. Combined inlab and in-situ testing results are presented in Table I-2.

Vegetation Samples
Vegetation (grass) samples were collected semi-annually from two primary locations (Cooling-Off Area and Reactor Area). Vegetation samples are no longer routinely collected from the third area (outside of hot cell building), since no man-made activity (other than fallout-related Cs-137) is detectable in this area. No man-made radionuclides were detected in any vegetation samples, as presented in Table I-3. Naturally occurring Be-7 (cosmic-origin) and K-40 (terrestrial-origin) were the primary nuclides detected.

Surface Water Samples
Surface (river) water samples, which were collected on the Etowah River upstream and downstream of the DFW (GNAL) Site, were tested for alpha, beta, H3, and gamma-emitting radionuclides. No man-made radionuclides were detected in any samples, as presented in Table I-4. Beta activity, which was just above the detection limit in some samples from both locations, is attributed primarily to naturally occurring radionuclides, including Pb-210 (long-lived radon-daughter product) and K-40, both of which are common in soil.

D&D Analysis of Reactor-Area Soil Sample Data for Long-Term Dose Estimate Long-term dose projections were made for a hypothetical, maximally exposed individual (MEI) who is assumed to continuously live, work, and farm on the decommissioned reactor site, using the D&D Dose Model, and using available sample analysis results for Co-60 and Eu-152. Doses due to these nuclides were projected to not exceed 4 mRem per year for all pathways combined, based on available survey and sample results. Since the reactor area contains sealed underground structures that haven't been surveyed by DNR, no allowance could be made for possible unknowns in these areas. Therefore, this dose estimate is only valid for current conditions, wherein the reactor-related underground structures remain sealed. Direct (external) radiation accounted for the majority (>95%) of this dose. Although current site-related (man-made) direct radiation doses may approach 10 mRem per year in some isolated spots, average dose rates that could be realistically received by the MEI would be less. Figure I-8 provides a breakdown of the dose projections by year and by pathway (Direct, Inhalation, Food, Water, and Total). Based on the current conditions and usage of this area, the site-related portion of the dose in this area is projected to decline to less than 1 mRem/year by the year 2015.

Section J - Sequoyah Nuclear Plant

Tennessee Valley Authority's Sequoyah Nuclear Plant is a two-unit Pressurized Water Reactor (PWR) facility located in Hamilton County, Tennessee approximately 20 miles northeast of Rossvile, Georgia. Westinghouse Electric Corporation supplied this facility, which has been in operation since 1980.

Several TLD and sample locations (Figure J-3)

are included in DNR's network, with most of the

monitoring focused on the northwest corner of

Georgia, between Rock City, Rossvile Ringold,

and Cohutta. DNR has monitored Plant Sequoyah

since approximately 1980, with no detectable Site-

related activity. However, several man-made

Figure J-1 (Sequoyah Nuclear Plant)

global-fallout-related radionuclides (including Nb-95, Zr-95, Ru-103, Ru-106, Ce-141, Ce-144, and Cs-

137) were detected many years ago (1981) during the Chinese weapons testing period. Global fallout-

related Cs-137 is the only man-made radionuclide that is still detectable.

Direct Radiation (TLDs): Direct radiation doses (Table J-1), as measured by TLDs (ThermoLuminescent Dosimeters) were within the normal (expected) range, with indicator locations (near Plant Sequoyah) measuring less than background (or control) locations (Figure J-2). No measurable offsite doses from Site operations were detected. Based on a review of soil sample results, naturally occurring radionuclides in the Uranium, Thorium, and Potassium series appear to account for over 99% of the direct radiation dose recorded on the TLDs, with fallout-related Cs-137 contributing the remainder. Indicator and background locations showed similar seasonal variability, which is attributed to seasonal variations in naturally occurring airborne radon. The direct radiation level at one background location (TLD # 113) did increase slightly (step-wise) after June 2000. This change is not attributed to Site operations, since the TLD is over 90 miles from the Site. Instead, this stepwise change is more likely to have been caused by construction-related activity involving the use of certain materials (such as concrete or gravel) which often contain naturally occurring radionuclides.

Soil Samples: Soil sample results (Table J-2) were normal with no detectable manmade radionuclides except for Cs-137, which is usually attributable to global fallout, rather than Plant operations. Naturally occurring radionuclides (Ra-226, Ra-228, K-40, and progeny) were also detected and accounted for most of the activity in the samples. Cs-137 results (Figure J-4) were generally comparable (within the errorbar range) for both locations, but more variability was observed at the SW-21 sample location.

Vegetation: Vegetation samples (Table J-4) were also normal, with no man-made activity attributable to Plant operations. Naturally occurring Be-7 and K-40 were found in most samples. Global fallout-related Cs-137 was non-detectable in all samples.

Section K - Oconee Nuclear Plant

Duke Power Company Plant Oconee is a three-unit Pressurized Water Reactor (PWR) facility located adjacent to Lake Keowee, near Senaca, South Carolina, approximately 20 miles northeast of Toccoa, Georgia. It discharges into the headwaters of the Savannah River upstream of Lake Hartwell. Babcock and Wilcox Company supplied this facility, which has been in operation since 1974.

Several land and aquatic sample locations (Figures

K-3 and K-4) are included in DNR's network,

which includes the northeast corner of Georgia,

around and including Lake Hartwell. DNR has

monitored Plant Oconee since approximately 1978,

with no detectable Site-related activity except for periodic low-level H-3 in surface water collected

Figure K-1 (Oconee Nuclear Plant)

from Lake Hartwell (near the Hartwell Dam). However, several global fallout-related radionuclides (Nb-

95, Zr-95, Ru-103, Ru-106, Ce-141, Ce-144, and Cs-137) were detected many years ago (1981) during

the Chinese weapons testing period. Cs-137 is the only one of these fallout-related gamma-emitting

radionuclides that is still detectable.

Surface Water: Low-level H-3 (up to 2x Bkg.) in surface water (Table K-5) was the only Site-related radionuclide detected during the current monitoring period, with the maximum concentration (400 pCi/l) equal to two percent of the Safe Drinking Water MCL (Figure K-2). Results were generally nondetectable for other tests (alpha, beta, and gamma-isotopic including Cs-137 and I-131).

Direct Radiation (TLDs): Direct radiation doses (Table K-1), as measured by TLDs (ThermoLuminescent Dosimeters) were within the normal (expected) range, with indicator locations (near Plant Oconee) measuring slightly more than background (or control) locations (Figure K-5). However, the slight difference isn't statistically significant: 4 + 4 mRem/yr. Based on a review of the soil sample results, naturally occurring radionuclides in the Uranium, Thorium, and Potassium series appear to account for over 99% of the direct radiation dose recorded on the TLDs. Indicator and background dosimeters showed similar seasonal variability, which is usually caused by seasonal variations in naturally-occurring airborne radon. No measurable, Site-related direct radiation was detected.

Soil Samples: Soil sample results (Table K-2) were normal with no detectable manmade radionuclides except for Cs-137, which is usually attributable to global fallout, rather than Plant operations. Naturally occurring radionuclides (Ra-226, Ra-228, K-40, and progeny) were also detected and accounted for most of the activity in the samples. Higher levels of naturally occurring K-40 were detected in soil samples from one location (SW-24) near Lake Hartwell. However, Cs-137 at this location was much lower (nondetectable) than at any of the other locations (Figure K-6). Cs-137 results were generally comparable (within the error bars) for all locations, except for the SW-24 location.

Ground Water: No detectable man-made radionuclides were detected (Table K-3) in ground water samples. Low-level alpha and beta activities (usually attributable to naturally occurring radionuclides, such as Ra-226 and Ra-228) were detected at two locations, but weren't attributed to Plant operations.
River Sediment: Sediment samples were collected from six locations in Lake Hartwell, with three samples taken in the Tugaloo segment of the Lake upstream of the Seneca River confluence (control locations) and three samples taken downstream of this confluence (indicator locations). No man-made radionuclides other than Cs-137 (primarily from global fallout) were detected in these sediment samples (Table K-6). Naturally occurring radionuclides, from the Uranium (Ra-226), Thorium (Ra-228), and Potassium (K-40) series, were also detected. No statistically significant differences were noted for Cs-137 in upstream vs. downstream samples (Figure K-7).

The spontaneous transformation of an unstable nuclide into a different nuclide, or into a different energy state of the same nuclide. This process results in the emission of radiation, and a reduction over time of the number of radioactive atoms.
A nuclide resulting from the radioactive decay of another nuclide. Decay products may be stable or radioactive.
A spontaneous nuclear transformation characterized by the emission of energy and/or mass from the nucleus of an atom. When many atoms of the same nuclide are present, the process is characterized by a definite half-life.
The amount of energy deposited by radiation in a given amount of material.
A measure of absorbed dose which expresses the biological effects of all types of radiation on a common scale. The common unit of measurement is the Roentgen Equivalent Man (Rem).
The radiation dose equivalent per unit time (e.g., mRem/yr).
An instrument to detect and measure accumulated radiation exposure or dose.
Radiation from a source outside the human body. Only gamma rays and neutrons are considered hazardous when the source is outside the human body. Extremely energetic beta particles may penetrate the dead layer of skin.
Airborne radioactive debris from a nuclear detonation or accident that has returned to the surface of the earth.
A nuclear transformation in which a nucleus splits into at least two smaller nuclei, commonly accompanied by the release of a large amount of energy. The resulting nuclei are often radioactive.

The periodic or continuous determination of radiation levels and the amount of radioactive materials present in a given area.
Radioactive materials, such as K-40, Uranium, Thorium, and their daughters, which occur naturally in the earth's crust and other radioactive materials, such as Be-7 and C-14, which are produced by natural processes in the earth's atmosphere.
A species of atom characterized by the makeup of its nucleus (i.e., the number of protons and neutrons and the energy content).
A radionuclide which, upon radioactive decay, yields a specified nuclide (a daughter) either directly or as a later member of the radioactive series.
A physical or biological mechanism whereby radioactive materials in the environment may reach man or another biological organism.
A type of nuclear reactor in which water within the core is maintained at sufficient pressure to prevent boiling. Steam to drive the turbine generator is produced in a heat exchanger known as a "steam generator".
