I. Summary and Conclusions This report on the Radiological Environmental Monitoring Program conducted for the Three Mile Island Nuclear Station (TMINS) by AmerGen covers the period 1 January 2005 through 31 December 2005. During that time period, 1,730 analyses were performed on 1334 samples. In assessing all the data gathered for this report and comparing these results with preoperational data and operational REMP data, it was concluded that the operation of TMINS had no adverse radiological impact on the environment.
Surface, drinking, effluent, storm, and ground water samples were analyzed for concentrations of tritium and gamma emitting nuclides. Surface, drinking, and effluent water samples were also analyzed for concentrations of 1-131. Drinking and effluent water samples were also analyzed for concentrations of gross beta.
Effluent water samples were also analyzed for concentrations of Sr-89 and Sr-!)0.
Ground water samples were also analyzed for concentrations of Sr-90. No Sr-89 and Sr-90 activities were detected. Gross beta and 1-131 concentrations detected were consistent with those detected in previous years. Tritium results in groundwater and several monthly results in surface, drinking and effluent water samples were due to TMINS activities or releases. These results will be discussed later in the report. Iodine-1 31 detected in effluent water was from upstream medical users. No other fission or activation products attributed to TMI release were detected.
Fish (predator and bottom feeder) and sediment samples were analyzed for concentrations of gamma emitting nuclides. Fish samples were also analyzed for concentrations of Sr-89 and Sr-90. No Sr-89 and Sr-90 activity was detected.
No fission or activation products were detected in fish. Cesium-137 levels detected in sediment were consistent with levels detected in previous years and were due to plant releases and fallout from nuclear weapons testing. No other TMINS-produced fission or activation products were detected in sediment.
Air particulate samples were analyzed for concentrations of gross beta and gamma emitting nuclides. Cosmogenic Be-7 was detected at levels consistent with those detected in previous years. No fission or activation products were detected.
High sensitivity 1-131 analyses were performed on weekly air samples. All results were less than the minimum detectable activity.
Cow milk samples were analyzed for concentrations of 1-131, gamma emitting nuclides, Sr-89 and Sr-90. No 1-131 and Sr-89 activities were detected.
Concentrations of naturally occurring K-40 were consistent with those detected in previous years. Sr-90 activities detected were consistent with those detected in previous years and were attributed to fallout from nuclear weapons testing. No other fission or activation products were found.
Food Product samples were analyzed for concentrations of gamma emitting nuclides (including 1-131) and Sr-90. Sr-90 activities were detected in both the indicator and control samples. This was a result of plant uptake of Sr-90 in soil as a result of past nuclear weapons testing. Concentrations of naturally occurring K-40 were consistent with those detected in previous years. No fission or activation products were detected.
Environmental gamma radiation measurements were performed quarterly using thermoluminescent dosimeters. Levels detected were consistent with those observed in previous years.
A practice of the TMI site is to analyze rodents for radioactivity as a part of the Non-routine REMP. This program is to determine the transport of radioactive materials to unrestricted areas by rodents. Analyses are performed by TMI personnel when samples are available. These results are presented in this report. A pest control program is in place at TMI. This program minimizes the potential for rodents to transport radioactive material to unrestricted areas.
II. Introduction The Three Mile Island Nuclear Station (TMINS), consisting of two pressurized water reactors (PWR), is located on the northern one-half of Three Mile Island in the Susquehanna River approximately 2.5 miles south of Middletown in Londonderry Township, Dauphin County, Pennsylvania. TMI-1 is owned and operated by AmerGen and became operational in 1974. TMI-2 is operated by GPU Nuclear, Inc. and owned by Metropolitan Edison (50%), Pennsylvania Electric (25%) and Jersey Central Power & Light (25%). TMI-2 became operational in 1978 and was shut down following the 1979 accident. At the end of 1993, TMI-2 was placed in a condition called Post-Defueling Monitored Storage. TMI-2 is maintained by Amergen under contract with GPU Nuclear.
A Radiological Environmental Monitoring Program (REMP) for TMINS was initiated in 1974. This report covers those analyses performed by Teledyne Brown Engineering (TBE), Global Dosimetry Solutions, Inc., and Environmental Inc. (Midwest Labs) on samples collected during the period 1 January 2005 through 31 December 2005.
A. Objective of the REMP The objectives of the REMP are to:
- 1. Evaluate the relationship between quantities of radioactive material released from the plant and resultant radiation doses to individuals from principal pathways of exposure.
- 2. Provide data on measurable levels of radiation and radioactive materials in the site environs.
- 3. To verify inplant controls for the containment of radioactive materials.
- 4. To determine buildup of long-lived radionuclides in the environmE nt and changes in background radiation levels.
- 5. To provide reassurance to the public that the program is capable of adequately assessing impacts and identifying noteworthy changes in the radiological status of the environment.
- 6. To fulfill the requirements of the TMI-1 and TMI-2 Technical Specifications.
B. Implementation of the Objectives The implementation of the objectives is accomplished by:
- 1. Identifying significant exposure pathways.
- 2. Establishing baseline radiological data of media within those pathways.
- 3. Continuously monitoring those media before and during Station operation to assess Station radiological effects (if any) on man and the environment.
Ill. Program Description A. Sample Collection Samples for the TMINS REMP were collected for AmerGen by Normandeau Associates, RMC Environmental Services Division (RMC).
This section describes the general collection methods used by RMC to obtain environmental samples for the TMINS REMP in 2005. Sample locations and descriptions can be found in Tables B-1 and B-2, and Figures B-1 through B-3, Appendix B. The collection procedures used by RMC are listed in Table B-3.
Aquatic Environment The aquatic environment was evaluated by performing radiological analyses on samples of surface water, drinking water, effluent water, storm water, ground water, fish, and sediment. Two gallon water samples were collected monthly from continuous samplers located at three surface water locations (A3-2, J1-2 and Q9-1), three drinking water locations (G15-2, G15-3 and Q9-1), and one effluent water location (K1-1). Control locations were A3-2 and Q9-1. Monthly grab water samples were taken from one storm water runoff location (EDCB). Grab ground water samples were collected quarterly at eight locations (48S, GP-1, GP-6, GP-8, GP-9, MS-22, OSF and OS-18), semiannually at 12 locations (GP-12, MS-2, MS-5, MS-8, MS-20, NW-A, NW-B, NW-C, NW-CW, OS-14, RW-1 and RW-2) and annually at seven locations (El-2, MS-1, MS-4, MS-7, MS-19, MS-21 and N2-1). In response to a special investigation, selected wells were sampled more frequently. All water samples were collected in new unused plastic bottles, which were rinsed at least twice with source water prior to collection. Fish samples comprising the flesh of two groups, bottom feeders and predators, were collected semiannually at an upstream control (BKG) and a downstream Indicator (IND) location.
Location IND could be affected by TMINS' effluent releases. Sediment samples composed of recently deposited substrate were collected semiannually at three locations (J2-1, K1-3 and Al-3). In addition, one sediment sample was collected annually at the EDCB. Location A1-3 was the control.
Atmospheric Environment The atmospheric environment was evaluated by performing radiological analyses on samples of air particulates, airborne iodine, milk, and food product. Airborne iodine and particulate samples were collected and analyzed weekly at seven locations (A3-1, E1-2, Fl-3, G2-1, H3-1, M2-1, and Ql 5-1). The control location was Ql 5-1. Airborne iodine and particulate samples were obtained at each location, using a vacuum pump with charcoal and glass fiber filters attached. The pumps were run continuously and sampled air at the rate of approximately one cubic foot per minute. The filters were replaced weekly and sent to the laboratory 1br analysis.
Milk samples were collected biweekly at four locations (K15-3, D2-1, E2-2, and G2-1) from March through November, and monthly from December through February. Milk was also collected at station F4-1 quarterly (March, June, September, and December). The control location was Kl 'i-
- 3. All samples were collected in new unused two gallon plastic bottles from the bulk tank at each location, preserved with sodium bisulfite, and shipped promptly to the laboratory.
Food products were collected annually at two locations (B10-2 and El-2).
The control location was B10-2. Four different kinds of vegetation samples were collected and placed in new unused plastic bags, and sent to the laboratory for analysis.
Ambient Gamma Radiation Direct radiation measurements were made using Panasonic 814 calcium sulfate (CaSO4) thermoluminescent dosimeters (TLD). The TLD locations were placed on and around the TMINS site as follows:
A site boundary ring consisting of 21 locations (A1-4, B1-1, B1-2, C1-2, D1-1, E1-4, F1-2, F1-4, G1-3, G1-5, G1-6, H1-1, Ji-i, J1-3, K1-4, 1-1, Mi-1, N1-3, P1-2, Q1-2, and Ri-i) near and within the site perimeter representing fence post doses (i.e., at locations where the doses will be potentially greater than maximum annual off-site doses) from TMIINS release.
An offsite ring consisting of 58 locations (A3-1, A5-1, A9-3, B2-1, B5-1, B10-1, C1-1, C2-1, C5-1, C8-1, D1-2, D2-2, D6-1, El-2, E2-3, E5-1, E7-1, F1-1, F2-1, F5-1, F10-1, G1-2, G2-4, G5-1, H3-1, H5-1, H8-1, J3-1, J5-1, J7-1 K2-1, K3-1, K5-1, K8-1, L1-2, L2-1, L5-1, L8-1, M1-2, M2-1, M5-1, M9-1, NI-I, N2-1, N5-1, N8-1, P1-1, P2-1, P5-1, P8-1, QM-A, Q2-1, Q5-1, Q9-1, R1 -2, R3-1, R5-1, and R9-1) extending to approximately 5 miles from the site designed to measure possible exposures to close-in population.
The balance of 11 locations (D15-1, F25-1, G10-1, G15-1, H15-1, J15-1, K15-1, L15-1, N15-2, Q15-1, and R15-1) represent control areas.
The specific TLD locations were determined by the following criteria:
- 1. The presence of relatively dense population;
- 2. Site meteorological data taking into account distance and elevation for each of the sixteen-22 1/2 degree sectors around the site, where estimated annual dose from TMINS, if any, would be most significant;
- 3. On hills free from local obstructions and within sight of the vents (where practical);
- 4. And near the closest dwelling to the vents in the prevailing downwind direction.
Each TLD station consists of two primary program TLD badges, each of which has three CaSO4 thermoluminescent phosphors enclosed in plastic, placed at each location in a frame located approximately three to six feet above ground level. Since each TLD responds to radiation independently, this provides six independent detectors at each station. The TLDs were exchanged quarterly and sent to Global Dosimetry for analysis.
B. Sample Analysis This section describes the general analytical methods used by TBE and Midwest Labs to analyze the environmental samples for radioactivity for the TMINS REMP in 2005. The analytical procedures used by the laboratories are listed in Table B-3.
In order to achieve the stated objectives, the current program includes the following analyses:
- 1. Concentrations of beta emitters in drinking and effluent water, and air particulates.
- 2. Concentrations of gamma emitters in surface, drinking, effluent, storm, and ground water, air particulates, milk, fish, sediment, and food products.
- 3. Concentrations of tritium in surface, drinking, effluent, storm, and ground water.
- 4. Concentrations of 1-131 in surface, drinking, and effluent water, air, milk and food products.
- 5. Concentrations of strontium in effluent and ground water, fish, milk, and food products.
- 6. Ambient gamma radiation levels at various site environs.
C. Data Interpretation Data were compared to previous years' operational data for consistency and trending. In addition, comparison to pre-operational data is sometimes made. For the purpose of this report, TMINS was considered operational at initial criticality. Several factors were important in the interpretation of the data:
- 1. Lower Limit of Detection and Minimum Detectable Concentration The lower limit of detection (LLD) was defined as the smallest concentration of radioactive material in a sample that would yield a net count (above background) that would be detected with only a 5% probability of falsely concluding that a blank observation represents a "real" signal. The LLD was intended as a before the fact estimate of a system (including instrumentation, procedure and sample type) and not as an after the fact criteria for the presence of activity. All analyses were designed to achieve the required TMINS detection capabilities for environmental sample analysis.
The minimum detectable concentration (MDC) is defined above with the exception that the measurement is an after the fact estimate of the presence of activity.
- 2. Net Activity Calculation and Reporting of Results Net activity for a sample was calculated by subtracting background activity from the sample activity. Since the REMP measures extremely small changes in radioactivity in the environment, background variations may result in sample activity being lower than the background activity effecting a negative number. An MDC was reported in all cases where positive activity was not detected.
Gamma spectroscopy results for each type of sample were grouped as follows:
For surface, drinking, effluent, storm, and ground water 11 nuclides, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Zr-95, Nb-95, Cs-1 34, Cs-1 37, Ba-1 40 and La-140 were reported.
For fish eight nuclides, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Cs-1 34 and Cs-1 37 were reported.
For sediment six nuclides, K-40, Mn-54, Co-58, Co-60, Cs-134 and Cs-137 were reported.
For air particulate six nuclides, Be-7, Mn-54, Co-58, Co-60, Cs-1 34 and Cs-1 37 were reported.
For milk five nuclides, K-40, Cs-134, Cs-137, Ba-140 and La-140 were reported.
For food products four nuclides, K-40, 1-131, Cs-134 and Cs-137 were reported.
Means and standard deviations of the results were calculated. The standard deviations represent the variability of measured results for different samples rather than single analysis uncertainty.

IV. Results and Discussion A. Aquatic Environment
- 1. Surface Water Samples were taken weekly from a continuous sampler at three locations (A3-2, J1-2, and Q9-1) and composited on a monthly schedule. Of these locations only J1-2 located downstream, could be affected by TMINS' effluent releases. The following analyses were performed.
Tritium Monthly samples from J1-2 and Q9-1 were analyzed for tritium activity (Table C-1.1, Appendix C). Positive tritium activity was detected in six of 24 samples, primarily at location J1-2 which is located immediately downstream of the TMINS effluent outfall. All samples ranged from <156 to 33,500 pCi/I. The increased tritium concentrations detected in March, August and September samples were a result of TMINS releasing more waste water in preparation of the Unit 1 refueling outage. The indicator surface water sample is taken just downstream of the liquid discharge outfall where mixing of liquid effluents with the river water is incomplete. More complete mixing is not achieved until liquid effluents pass over the York Haven Dam. This water is normally not consumed by humans. The concentrations detected were well below any regulatory limits. (Figures C-1 and C-2, Appendix C).
Iodine Monthly samples from location A3-2 were analyzed for iodine-131 activity (Table C-1.2, Appendix C). This is a control or background station sampled because of a known medical facility that has discharges into the surface water upstream of TMI. Iodine-131 activity was not detected.
Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table C-1.3, Appendix C). All nuclides were less than the MDC.
- 2. Drinking Water Monthly samples were collected from continuous water samplers at three locations (G15-2, G15-3, and Q9-1). Two locations (G15-2 and G15-3) could be affected by TMINS' effluent releases. The following analyses were performed:
Gross Beta Monthly samples from all locations were analyzed for concentrations of gross beta. (Tables C-11.1, Appendix C). Gross beta activity was detected in 30 of 36 samples. The values ranged from <2.0 to 5.4 pCi/l. Concentrations detected were consistent with those detected in previous years (Figures C-3, Appendix C).
Tritium Monthly samples from all locations were analyzed for tritium activity (Table C-11.3, Appendix C). Tritium activity was detected in one of 36 samples. Activity was detected in eight of 36 samples. All samples ranged from <153 to 600 pCi/l. The elevated results for September and October were a result of releasing more waste water in preparation of the Unit 1 refueling outage. Additionally, these releases occurred during abnormally low river flows. The concentrations were well below any regulatory limits. A dose estimate was performed by averaging the sample results for these two months. The hypothetical dose to the maximum exposed individual from consuming this water would have been 0.01 mrem/year to the liver of a child. (Figures C-4, Appendix C).
Gammai Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table C-11.4, Appendix C). All nuclides were less than the MDC.
- 3. Effluent Water Monthly samples were collected from a continuous water sampler at one location (K1-1). The following analyses were performed:
12 -
Gross Beta Monthly samples from location K1-1 were analyzed for concentrations of gross beta. (Tables C-111.1, Appendix C). Gross beta was detected in 11 of 12 samples. The values ranged from
<2.6 to 9.9 pCi/l. Concentrations detected were consistent with those detected in previous years.
lodine-1 31 Monthly samples from location KI-1 were analyzed for concentrations of iodine-131. (Tables C-111.1, Appendix C). Iodire-131 activity was detected in one sample. The values ranged from
<0.3 to 1.3 pCi/l. The positive result is not believed to be due to TMINS effluents. Historically, 1-131 has been detected sporadically in effluent water and not in the control stations. No 1-131 was identified in any tank effluent pre-release samples, and 1-131 was not detected in any other downstream surface or drinking water samples. Effluent water is not consumed by humans.
Tritium Monthly samples from location K1-1 were analyzed for tritium activity (Table C-111.1, Appendix C). Tritium activity was detected in four samples. The values ranged from <158 to 157,000 pCi/l. The elevated results for March, July, August and September were a result of releasing more waste water in preparation of the Unit I refueling outage. These results are from the liquid discharge mixing basin. The concentrations detected agree with those obtained from the TMINS Effluent Monitoring Program. The concentrations were well below any regulatory limits.
Strontium Semiannual samples from location K1-1 were analyzed for Sr-89 and Sr-90 (Table C-111.1, Appendix C). No strontium activity was detected. The highest MDC was calculated at 2.3 pCi/I for Sr-89 and at 0.6 pCi/l for Sr-90.
Gamma Spectrometry Samples from location K1-1 were analyzed for gamma emitting nuclides (Table C-111.2, Appendix C). All nuclides were less than the MDC.
- 4. Storm Water Monthly grabs from the storm water collection basin (EDCB) were composited quarterly. The following analyses were performed:
Trititim All samples from location EDCB were analyzed for tritium activity (Table C-IV.1, Appendix C). Tritium activity was detected in three samples. The values ranged from <167 to 393 pCi/I and were due to airborne releases of H-3 from TMI. Concentrations detected were consistent with those detected in previous years.
Gamma Spectrometry Samples from location EDCB were analyzed for gamma emitting nuclides (Table C-IV.1, Appendix C). All nuclides were less than the MDC.
- 5. Ground Water Quarterly, semiannual and annual grab samples were collected at 27 locations (48S, GP-1, GP-6, GP-8, MS-22, OSF, OS-18, GP-9, GP-12, MS-2, MS-5, MS-20, NW-A, NW-B, NW-C, NW-CW, OS-14, RW-1, RW-2, El-2, MS-1, MS-4, MS-7, MS-8, MS-19, MS-21 and N2-1). The following analyses were performed:
Tritium All samples from the locations were analyzed for tritium activity (Table C-V.1, Appendix C). Tritium activity was detected in 43 of 55 samples. The values ranged from <103 to 18,500 pCi/l. In July of 2005 TMINS responded to elevated results in well RW-2. The sampling frequency for selected wells was increased. The results are listed in Table F-1.1, Appendix F. Tritium activity was detected in 83 of 104 samples. The values ranged from <103 to 31,100 pCi/l. TMINS discovered and fixed a leaking pipe in September.
The maximum concentration in RW-2 was detected in September.
Tritium concentrations trended downward the remainder of the year. Offsite groundwater tritium concentrations were unaffected by this event.
Strontium Annual samples from six locations (48S, OSF, MS-2, MS-5, MS-8 and OS-14) were analyzed for Sr-90 (Table C-V.2, Appendix C).
No Sr-90 activity was detected. The highest MDC was calculated at <0.4 pCi/I.
Gamma Spectrometry Quarterly samples from two locations (48S and OSF) and annual composite samples from eight locations (MS-2, MS-5, MS-8, MS-20, MS-22, OS-14, RW-1 and RW-2) and annual grab samples from two locations (El-2 and N2-1) were analyzed for gamma emitting nuclides (Table C-V.2, Appendix C). All nuclides were less than the MDC.
- 6. Fish Fish samples comprised of bottom feeders and predators were collected at two locations (IND and BKG) semiannually. Location IND could be affected by TMINS' effluent releases. The following analyses were performed:
Strontium The edible portions of fish samples from both locations were analyzed for Sr-89 and Sr-90. (Table C-VI.1, Appendix C). No strontium activity was detected. The highest MDC was calculated at <21 pCi/kg wet for Sr-89 and at <5 pCi/kg wet for Sr-90.
Gamma Spectrometry The edible portions of fish samples from both locations were analyzed for gamma emitting nuclides (Table C-V1.2, Appendix C).
Naturally occurring K-40 was found at all stations and ranged from 2,290 to 4,020 pCi/kg wet and was consistent with levels detected in previous years. No fission or activation products were found.
- 7. Sediment Aquatic sediment samples were collected at three locations (Al-3, J2-1 and K1-3) semiannually. In addition, location EDCB was sampled annually. Of these locations two (J2-1 and K1-3) could be affected by TMINS' effluent releases. The following analysis was performed:
Gamma Spectrometry Sediment samples from all four locations were analyzed for gamma emitting nuclides (Table C-VII.1, Appendix C). Nuclides detected were naturally occurring K-40, and the fission product Cs-137.
K-40 was found at all stations and ranged from 7,720 to 16,300 pCi/kg dry. Concentrations of the fission product Cs-1 37 were found in six of seven samples (Figure C-5, Appendix C). Location EDCB had the highest average concentration of 294 pCi/kg dry.
The activity detected was consistent with those detected in the previous years. No other TMINS fission or activation products were found.
B. Atmospheric Environment
- 1. Airborne
- a. Air Particulates Continuous air particulate samples were collected from seven locations on a weekly basis. The seven locations were separated into three groups: Group I represents locations within the TMINS site boundary (El-2 and F1-3),
Group II represents the location at an intermediate distance from the TMINS site (A3-1, G2-1, M2-1, and H3-1), and Group IlIl represents the control location at a remote distance from TMINS (Q15-1). The following analyses were performed:
Gross Bets Weekly samples were analyzed for concentrations of beta emitters (Table C-VIII.1 and C-VIII.2, Appendix C).
Detectable gross beta activity was observed at all locations.
Comparison of results among the three groups aid in determining the effects, if any, resulting from the operation of TMINS. The results from the On-Site locations (Group I) ranged from <7 to 32 E-3 pCi/M3 with a mean of 17 E-3 pCi/M3 . The results from the Offsite location (Group II) ranged from <6 to 37 E-3 pCi/M 3 with a mean of 18 E-3 pCi/M3 . The results from the Control locations (Group l1l) ranged from <6 to 34 E-3 pCi/M 3 with a mean of 17 E-3 pCi/M3 . Comparison of the 2005 air particulate data with previous years data indicate no effects from the operation of TMINS (Figure C-6, Appendix C). In addition a comparison of the weekly mean values for 2005 indicate no notable differences among the three groups (Figure C-7, Appendix C).
Gamma Spectrometry Weekly samples were composited quarterly and analyzed 1or gamma emitting nuclides (Table C-VIl.3, Appendix C).
Naturally occurring Be-7 due to cosmic ray activity was detected in 27 of 28 samples. These values ranged from
<21 to 96 E-3 pCi/M3 . All other nuclides were less than the MDC.
- b. Airborne Iodine Continuous air samples were collected from seven (A3-1, E1-2, F1-3, G2-1, H3-1, M2-1, and Q15-1) locations and analyzed weekly for 1-131 (Table C-IX.1, Appendix C). All results were less than the MDC.
- 2. Terrestrial
- a. Milk Samples were collected from four locations (K1 5-3, D2-1, E2-2, and G2-1) biweekly March through November and monthly December through February. Station F4-1 was sampled quarterly. The following analyses were performed:
Iodine-131 Milk samples from all locations were analyzed for concentrations of 1-131 (Table C-X.1, Appendix C). All results were less than the MDC.
Strontium Milk samples from all locations were composited quarterly and analyzed for Sr-89 and Sr-90 (Table C-X.2, Appendix C). No Sr-89 activity was detected. Sr-90 activity was detected. The values ranged from <0.3 to 2.5 pCi/I. The activity detected was consistent with those detected in the pre-operational years (Figure C-8, Appendix C).
Gamm; Spectrometry Milk samples from all locations were analyzed for concentrations of gamma emitting nuclides (Table C-X.3, Appendix C).
Naturally occurring K-40 activity was found in all samples.
The values ranged from 944 to 1,680 pCi/I. All other nuclides were less than the MDC.
- b. Food Products Samples were collected from two locations (B10-2 and E1-2) annually. The following analyses were performed:
Strontium Each food product sample was analyzed for concentrations of Sr-90 (Table C-XI.1, Appendix C). Sr-90 activity was not detected.
Gamma Spectrometry Each food product sample was analyzed for concentrations of gamma emitting nuclides (Table C-XI.1, Appendix C).
Naturally occurring K-40 activity was found in all samples.
The values ranged from 1,790 to 4,030 pCi/I. All other nuclides were less than the MDC.
- c. Rodents No rodents were collected during 2005.
C. Ambient Gamma Radiation Ambient gamma radiation levels were measured utilizing Panasonic 814 (CaSO4) thermoluminescent dosimeters. Ninety TLD locations were established around the site. Results of TLD measurements are listed in Tables C-XII.1 to C-XII.3, Appendix C.
TLD measurements were below 10 mR/standard month, with a range of 2.0 to 7.7 mR/standard month. A comparison of the Site Boundary and Intermediate Distance data to the Control Location data, indicate that the ambient gamma radiation levels from the Control Locations D15-1, F25-1, G10-1, G15-1, H15-1, J15-1, K15-1, L15-1, N15-2, Q15-1, and R15-1 were consistently higher. The historical ambient gamma radiation data from Locations D15-1, F25-1, G10-1, G15-1, H15-1, J15-1, K15-1, L15-1, N15-2, Q15-1, and R15-1 were plotted along with similar data from the Site, Intermediate Distance and Outer Ring Locations (Figure C-9, Appendix C). Locations D15-1, F25-1, G10-1, G15-1, H15-1, J15-1, K15-1, L15-1, N15-2, Q15-1, and R15-1 have a historical high bias, but tracked with the data from all three groups, this bias is most likely due to radon and other naturally occurring nuclides, e.g. K-40, emanating from the ground.
D. Land Use Survey A Land Use Survey conducted in the September and October 2005 growing season around the Three Mile Island Nuclear Station (TMINS) was performed by Normandeau Associates, .RMC Environmental Services Division for AmerGen to comply with Sections 2.15 and 3.4.2 of the Plant's Offsite Dose Calculation Manual (ODCM). The purpose of the survey was to document the nearest resident and milk-producing animal in each of the sixteen 22 Y/2 degree sectors around the site. There were no changes required to the TMINS REMP, as a result of this survey. The nearest residence in the West sector changed from 560 m to 1120 m based on the residence survey. The Receptor files in the dose calculation software were changed. The results of this survey are summarized below.

C1 Cor nSamok No reactor produced gamma emitting radionuclides were detected.
Strontium-90 was detected in these samples. The detection of Sr-90 in these samples is not due to TMINS effluents for the following reasons:
- Sr-90 was not detected in any in-plant effluent sample results
- 1-131 was released into the atmosphere at low levels from TMINS consistently and it was not detected in these environmental samples
- Sr-90 is detectable in the soil from fallout from past nuclear weapon tests
. Plants uptake strontium as a soil nutrient via their roots
- Sr-90 was detected in the control samples The Sr-90 detected in all these samples was a result of plant uptake of Sr-90 in the soil. The large variation in the concentrations is due to different bioaccumulation factors between plant species.
E. Summary of Results - Inter-Laboratory Comparison Program The primary and secondary laboratories analyzed Performance Evaluation (PE) samples of air particulate, air iodine, milk, soil, vegetation and water matrices (Appendix E). The PE samples, supplied by Analytics Inc.,
Environmental Resource Associates (ERA) and DOE's MAPEP, were evaluated against the following pre-set acceptance criteria:
- 1. Analytics Evaluation Criteria Analytics' evaluation report provides a ratio of TBE's result and Analytics' known value. Since flag values are not assigned by Analytics, TBE-ES evaluates the reported ratios based on internal QC requirements, which are based on the DOE MAPEP criteria.
- 2. ERA Evaluation Criteria ERA's evaluation report provides an acceptance range for control and warning limits with associated flag values. ERA's acceptance limits are established per the USEPA, NELAC, state specific PT program requirements or ERA's SOP for the Generation of Performance Acceptance Limits, as applicable. The acceptance limits are either determined by a regression equation specific to each analyte or a fixed percentage limit promulgated under the appropriate regulatory document.
- 3. DOE Evaluation Criteria MAPEP's evaluation report provides an acceptance range with associated flag values.
The MAPEP defines three levels of performance: Acceptable (flag =
"A"), Acceptable with Warning (flag = "W"), and Not Acceptable (flag = "N"). Performance is considered acceptable when a mean result for the specified analyte is +/- 20% of the reference value.
Performance is acceptable with warning when a mean result falls in the range from +/-20% to +/-30% of the reference value (i.e., 20% <
bias < 30%). If the bias is greater than 30%, the results are deemed not acceptable.
For the primary laboratory, 18 out of 19 analytes met the specified acceptance criteria. Two samples did not meet the specified acceptance criteria for the following reasons:
- 1. Teledyne Brown Engineering's Analytics' September 2005 air particulate Fe-59 ratio of 1.35 exceeded the upper control limit of 1.30 due to a new technician not counting the air particulate in a petri dish.
For the secondary laboratory, 19 out of 23 analytes met the specified acceptance criteria. Four samples did not meet the specified acceptance criteria for the following reasons:
- 1. Environmental Inc.'s ERA's November 2005 water Gross Alpha result of 41.1 pCi/L exceeded the upper control limit of 33.4 pCi/L.
This was due to using an Am-241 efficiency instead of a Th-232 efficiency when counting the sample. Using the correct efficiency gave a result of 27.0 pCi/L.
- 2. Environmental Inc.'s ERA's November 2005 water Ra-228 result of 5.5 pCi/L exceeded the upper control limit of 5.0 pCi/L due to presence of radium daughters. Delay in counting 100 minutes gave a result of 4.01 pci/L.
- 3. Environmental Inc.'s MAPEP's January 2005 air particulate Sr-90 result of 2.2 exceeded the upper control limit of 1.76 Bq/kg.
Reanalysis result was 1.56 Bq/kg.
- 4. Environmental Inc.'s MAPEP's July 2005 soil Am-241 result of 48.4 exceeded the lower control limit of 56.77 Bq/kg due to incorrect sample weight being used in the calculation. When recalculated with the correct sample weight, the result was 97.0 Bq/kg.
The Inter-Laboratory Comparison Program provides evidence of "in control" counting systems and methods, and that the laboratories are producing accurate and reliable data.

b Unless otherwise indicated, the laboratory result is given as the mean +/- standard deviation for three determinations.
' Results are presented as the known values, expected laboratory precision (1 sigma, 1 determination) and control limits as provided by ERA.
dThe original samples were calculated using an Am-241 efficiency. The samples were spiked with Th-232. Samples were recounted and calculated using the Th-232 efficiency. Results of the recount: 27.01 +/- 2.35 pCi/L.
e Decay of short-lived radium daughters contributed to a higher counting rate. Delay of counting for 100 minutes provided better results.
The reported result was the average of the first cycle of 100 minutes, the average of the second cycle counts was 4.01 pCi/L E-8
