SUMMARY
AND CONCLUSIONS I I I I I I
[ I I. SUtiliARY AflD C0tlCLUSI0flS This report on the radiological environmental monitoring program conducted at I the Peach Bottom Atomic Power Station for Philadelphia Electric Company by Radiation fianagement Corporation covers the period January 1,1981 to December 31, 1981. During this period 4542 analyses were performed on 3922 samples. Surface water and discharge water samples were analyzed for concentrations of tritium, gross beta, and ganna-emitting nuclides. Surface water was also analyzed for concentrations of gross alpha. Comparisons of unaffected stations with potentially affected stations, in Conowingo Pond, showed no significant difference in concentrations of the radionuclides studied. It sas shown that no significant differences existed between the preoperational and operational periods; therefore, it can be concluded that the levels of radioactivity in Conowingo Pond water have not been measurably influenced by the operation of the Peach Bottom Atomic Power Station. High sensitivity I-131 analyses were perfonaed on weekly air samples. All msults were less than the minimum detectable level. liigh sensitivity I-131 analyses were also performed on weekly milk samples while cows were on pasture and on monthly samples when cows were not grazing. All results were less than the minimum detectable level. Soil samples were analyzed for concentrations of Sr-89, Sr-90 and ganna-emitting nuclides and levels observed were similar to preoperational data. Environmental ganaa radiation measurements were made using thermoluminescent dosimeters . Results from the site-boundary, middle and outer rings were found to be not significantly different, so it can be concluded that the operation I of Peach Bottom Atomic Power Station did not produce measurable levels of ambient ganna radiation at any off-site location. In assessing all the data gathered for this report and comparing the results I with preoperational data, it was evident that the operation of the Peach Bottom Atomic Power Station resulted in no significant radiological impact on the envi-ronment.

E E I I I I I II. INTRODUCTION I I I I I I I
II. IflTRODUCTI0ft Radiation fianagement Corporation (Rf1C) began conducting a radiological environmental monitoring program in September 1970 for the Philadelphia I Electric Company in connection with the Peach Bottom Atomic Power Station (PBAPS) located in Peach Bottom Township, York County, Pennsylvania. This Rf4C pmgram complements an existing program being conducted by others which has been carried out since fiarch 1960. PBAPS .is located along the Susquehanna River between lloltwood and Conowingo Dams. The fourteen mile long pond created by Conowingo Dam is called Conowingo Pond. The initial loading of fuel into Peach Bottom Unit #1, a 40 ftWe (flet) high temperature gas-cooled reactor, was started on February 5,1966, and initial criticality was achieved fiarch 3,1966. Final shutdown of Peach Bottom Unit #1 was on October 31, 1974. Peach Bottom Unit #2 and #3 are boiling water reactors each with a power output of approxi-mately 1050 t4We (flet). The first fuel was loaded into Unit #2 on August 9,1973, and criticality was first achieved on September 16, 1973. The fuel was loaded into Unit #3 on July 5,1974 and criticality was first achieved on August 7,1974. Peach Bottom Unit #2 first mached full power I on June 16, 1974. Peach Bottom Unit #3 first reached full power on December 21, 1974. Results of the R!iC portion of the overall regional radiological environmental monitoring program have been reported in semi-annual and annual reports. Semi-annual reports were discontinued after 1975. This report contains data for sam-ples representing the period January 1,1981 through December 31, 1081. A special preoperational report (1) for Peach Bottom Units #2 and #3 has been issued previously which sumarizes results of all analyses performed by R!iC on samples collected from the start of the Rf4C portion of the overall program thmugh August 8,1973, the day before fuel was first loaded into Peach Bottom Unit #2.

III. R!iC PROGRAli DESCRIPTI0fl A. SAf4PLE COLLECTI0ft AflD TLD PLACEf4EllT PROCEDURES The program being conducted by R!ic is described in Tables I and II and Figures 1-3. l
- 1. Sample Collection I a. Water (except precipitation)
All samples were collected in new polyethylene bottles. All persons involved in sagle collection and handling were ad-vised not to wear tritium luminous dial watches in order to avoid possible cross contamination from that source. Sample containers were rinsed at least twice with the water to be sampled before collection. All water samples were grab samples except those collected at stations ILL, lliti, 61 and 4L. Weekly samples were taken from a tank which continually collects a sample at these four locations. The weekly samples were co@osited into a monthly sample for analysis. Collection methods are described in more detail in Table II, Section V.
- b. Precipitation Precipitation was collected in an apparatus consisting of a new polyethylene bottle with a plastic funnel 8 inches in diameter. The bottle was replaced monthly and the sample bottle was shipped to Rf4C for analysis. The amount of precipitation was recorded continuously by a separate rain gauge at station 1A.
- c. Air Particulates Air particulate samples were obtained using a vacuum sampler and glass fiber filters, approximately 2" in diameter. The filter was replaced weekly and sent to Rf4C for analysis. The vacuum sampler was run continuously at approximately 1 cubic foot per minute.
- d. Air Iodine air iodine samples were obtained using a vacuum sampler and charcoal filters, approximately 2" in diameter. The filter was replaced weekly and sent to Rf4C for analysis. The vacuum sampler was run continuously at approximately 1 cubic foot per minute.
- e. f4 ilk f4 ilk samples were collected in new polyethylene bottles from the bulk tank at each fam, refrigerated and shipped inrediately.
fio preservative was added. 5
Soil I f. Soil samples consisting of seven cores, 2" in diameter and 6" deep were collected from a 50 X 50 ft. area at each sampling location. Top soil (upper 1 inch) and bottom soil (lower 5 inches) were separated, then sealed in separate plastic bags, and shipped to RMC.
- 2. TLD Placement A system using thermoluminescent dosimeters (TLDs) was used to measure the direct radiation levels in the PBAPS environment.
The TLD stations were placed on and around the Peach Bottom Site using the "three ring concept". Two on-site stations, designated as plant complex stations are not included in any of the three rings.
- a. A site boundary ring near and within the site perimeter, representing fencepost doses, i.e., at locations where the doses are greater than maximum annual off-site doses from Station releases;
- b. A middle ring extending to approximately 10 miles from the Site, designed to measure possible exposures to close-in population;
- c. An outer ring extending fmm approximately 10 to about 60 miles from the Site, and considered not to be affected by Station releases;
- d. The specific location of each station was determined by the following criteria:
(1) The presence of relatively densely populated areas; (2) From Site meteorological data taking into account distance and elevation for each of the 36 ten-degree sectors around the Site, where estimated annual dose from the Station, if any, would be more significant; (3) On hills and (where practical) within sight of the stack, and free from local obstructions; (4) Near the closest house to the stack in the prevailing downwind di rection.
- e. Each TLD set (4 TLDs per set) was placed in a sealed polyethy-lene package to verify the integrity of the dosineters when collected. Two packages were kept in a locked formica " bird-house" or polyethylene jar, about,six feet above the ground or supporting surface at each location. At each station one package was exchanged for measurement on a monthly schedule, and one on a quarterly schedule.

I B. PROGRAli CHAfiGES Effective with samples collected in 1981, the following changes have been made. All of the changes are in accordance with current f4RC guidelines for monitoring programs. fione of these changes involve the PBAPS technical specification program. Data Data for alpha and beta emitters found in the insoluble fraction of water samples were reported in units of pCi/g(ashed). These units were used to reduce the fluctuation in the activities detected in surface and discharge waters when silt loading due to runoff occurs in Conowingo Pond. C. AllALYSES PERFORf1ED The schedule of analyses perfomed by PJiC is listed by sa@le type'in Table II. This schedule was followed except where noted below. Table III lists the type and number of analyses performed during this period by sample type and station location. liethods used in performing these I analyses can be found in Appendix A of PBAPS Radiological Environmental fionitoring Program Report #12, January 1,1976 - December 31, 1976.

IV. RESULTS AfiD DISCUSSI0tl A. DATA IllTERPRETATI0ti AllD STATISTICAL Af4ALYSIS Several factors am important in the interpretation of the data. In order to avoid undue repetition in the discussion which follows, these ( factors are described below.
- 1. Grab Sampling Grab sampling is a useful and acceptable procedure for taking envi-ronmental samples of a medium in which the concentration of radio-nuclides is expected to vary slowly with time or where intermittent sampling is deemed sufficient to establish the radiological charac-teristics of the medium. This method, however, is only representa-tive of the sampled medium for that specific location and instant of time. As a msult, variation in the radionuclide concentrations of the samples will normally occur. Since these variations will tend to counterbalance one another, the extraction of averages based upon repetitive grab samples is valid.
- 2. 141nimum Detectable Levels (f4DL)
It is characteristic of environmental monitoring data that many results occur at or below the specified detection level. Formal statistical error analysis of groups of such data is difficult. Pragmatic approaches j to the problem include counting the detection level entries as zem, as half the detection level value, or as full detection level value. For reporting and calculation of averages in this report, any result occurring at or below the minimum detectable level is considered to be at that level. [ Averages obtained using this method are therefore biased high.
- 3. Standard Deviation of Analytical Results Within the data tables an approximate 95% (2 sigma) confidence interval is supplied for those data points at and above the minimum detectable level. These intervals represent the range of values into which 95%
f- of mpeated counts of the prepared sample would fall.
- 4. Table tieans and Standard Deviations Results for each type of sample were grouped according to the analysis pe rformed, lieans and standard deviations of these results were calcu-
[ lated. These standard deviations repmsent the variability of measured 'i results for different samples rather than single analysis uncertainty. For these calculations, all results below the 14DL were considered to be ( at the 14DL. As a result, the means are biased high, and the standard ( deviations are biased low. ( 9 {
I B. DISCUSSION OF RESULTS Results are suninarized in brief fonn in Tables IV, V and VI (Section V). Tables of results for individual sa@le types and analyses per-fonned can be found in Section V, Tables VII to XXVII. presentations of msults can be found in Section VI. Graphical l-
- 1. Surface Water Samples were taken from eight stations on a monthly schedule.
Three stations (1LL, 4L and 61) were continuous composite sam- g ples and five (1Q, 4F, 4G, 6A and 13A) were grab sanples. Station 138 was sampled a total of six times in 1981. Of these stations, 5 seven could be affected by releases from Peach Bottom Atomic Power Station. The remaining stations (6A and 6I) were above Holtwood Dam and, therefore, could not be affected by plant discharges (re-fer to Figures 1 and 2, Section VI, for station locations). The following analyses were perfonned on surface water samples.
- a. Tritium Total samples from seven stations were analyzed for concentrations of aqueous tritium. Samples from stations ILL,1Q, 4L and 6I were analyzed on a monthly basis, while samples fmm stations 4F, 6A and 13A were composited monthly into a quarterly sample. Results of this analysis of surface water samples can be found in Tables VII and VIII, Section V. The concentrations detected were well within the range found during the Peach Bottom Units #2 and #3 preoperational g period (1). Graphical comparisons of the unaffected stations (6A g and 6I) above Holtwood Dam with potentially affected stations (4F and 4L) at Conowingo Dam showed no detectable addition of tritium to Cor,0 din o Pond from the operation of PBAPS (Figums 4 and 5, Section VI . l
- b. Gross Alpha Samples from four stations (4F, 4L, 6A and 6I) were analyzed for I gross alpha concentrations in the soluble and insoluble fractions. m l Results of gmss alpha' analysis in surface water samples can be g found in Tables VII and VIII, Section V. Results at all locations l were generally at or below the minimum detectable level in the solu-l ble fraction. Results of the insoluble fraction indicated a small l amount of activity present. Although no direct comparison can be
! made with data collected in previous years, the activity found was within the range of the MDL values observed.
- c. Gross Beta Samples from all stations, were analyzed for concentrations of gross beta in the soluble and insoluble fractions. Results of l
gross beta analysis in surface water sanples can be found in Tables VII and VIII, Section V. The concentrations detected in the soluble fraction were within the range observed during the preoperational l 10 l I
period for Units #2 and #3 (1). Detectable activities were ob-served in the insoluble fraction of surface water. Although not directly comparable with data collected in previous years, the activities observed with a few exceptions were within the range of the MDL values. Station 4G showed a high insoluble gross beta concentration (600100 pCi/g); however, the heti-vity per volume of water was minimal (2.7 .4 pCi/1). This ( high concentration per unit mass of sediment was the result of a small positive count rate being amplified by a very small sediment mass. A graphical comparison of two Cono-wingo Dam stations (4F and 4G) wit; one Holtwood Dam station (6A) showed the results of the soluble and insoluble fractions to be generally the same for all thme locations (Figures 6 and 7 Section VI). de Gamma Spectrometry Samples from all stations wem analyzed for gamma-emitting nuclides by gamma spectrometry. Results of gamma spectrometry on surface water samples can be found in Table IX, Section V. The nuclides searched for were below tha minimum detectable level,
- e. Iodine-131
( Samples collected durirg the last week of each month from 1/24/81 to 1/09/82 from two stations (4L and 61) were analyzed for concen-l trations of I-131. 'asults of I-131 analysis of surface water sam-l ples can be found in Table VIII, Section V. Most results were below the minimum detectable level. Detectable concentrations were found r at station 4L in February, October and Novenber and at station 61 in February, July October and November. The I-131 activity was ( attributed to upstream sources.
- 2. Discharge Water
( Samples were taken from two stations (IM and IMM) on a monthly sche- [ dule (refer to Figure 1 Section VI, for station locations). The i following analyses wem performed on discharge water samples,
- a. Tritium Total samples from both stations were analyzed for concentrations of aqueous tritium on a monthly basis. Results of tritium analysis in
( discharge water samples can be found in Tables X and XI, Section V. 5 The concentrations detected were within the range found during the Peach Bottom Units #2 and #3 preoperational period (1). A graphical [ comparison of concentrations of aqueous tritium msults for conposite t surface water and discharge water samples showed no significant dif-ferences (Figure 8, Section VI). ( b. Gross Betc Monthly samples from both stations were analyzed for gross beta concen-trations in the soluble and insoluble fractions. Results of these { 11 ( L - _ - - - - - - - - - - - - - -
I analyses in discharge water samples can be found in Tables X and XI, g Section V. The concentrations detected in the soluble and insoluble g fractions were similar to those observed in surface water samplas (Figures 9 and 10, Section VI).
- c. Gamma Spectrometry Samples from both stations vare analyzed for ganna-emitting nuclides by spectrometry. Results or gamma spectrometric analysis are given in Table XII, Section V. All nuclides were less than the minimum detectable level .
- 3. Well Water I Samples were taken from four stations on a quarterly schedule. Two stations (1U and IV) were located within the Site area. The other stations were located approximately one mile (station 40) and 10 miles (station 7) from the Plant. These station locations are a shown in Figures 1 and 2, Section VI. The following analyses were g performed on well water samples,
- a. Tritium Total samples from all four stations were analyzed for aqueous tritium concentrations. Results of tritium analysis of well water samples can E be found in Table XIII, Section V. Results of all samples were within 5 the range found during the Peach Bottom Units #2 and #3 preoperational period (1). A graphical comparison of the distant site-area, and on- a site wells showed that tritium levels have been gradually decreasing g with time due to the cessation of routine atmospheric nuclear weapons testing (Figure 11, Section VI).
- b. Gross Beta Samples from all four stations were analyzed for gross beta concentra-tions in the soluble and insoluble fractions. Results of gross beta analysis on well water samples can be found in Table XIII, Section V.
The concentrations detected in the soluole fraction were within the range observed during the Peach Bottom Units #2 and #3 preoperational period (1). Although not directly comparable to data collected in pmvious years most concentrations detected in the insoluble fraction l were similar to data observed for surface and discharge water. Station l 40 showed a high insoluble gross beta concentration (1500 800 pCi/g) E relative to the other stations. The result was due to a small amount of insoluble particulates present in the sample,
- 4. Precipi tation Precipitation was collected from two stations on a monthly schedule.
Station 1A is located at the on-site Peach Bottom Weather Station #1. Station 8, located in Colora, MD., is approximately 10 miles from the Site (for station location, refer to Figures 1 and 2 Section VI). The g following analyses were performed on precipitation samples. 5 12 I I
- a. Gross Beta Monthly samples were analyzed for gross beta concentrations in the total sample. Results of gross beta analysis in precipitation sam-ples can be found in Table XIV, Section V. Most concentrations de-tected wem within the range found during the Peach Bottom Units #2 and #3 preoperational period (1). Samples collected from stations IA and 8 between 1/31/81 to 8/01/81 showed higher levels than the remainder of the year. These values reflect the contineed fallout from the Chinese atmospheric nuclear weapons test of October,1980.
Data reported for stations IA and 8 on 9/06/81 were significantly different (43 3 and 51, respectively). The difference was attri-buted to concentrations of Be-7 and Zrtib-95 found at station 1A (Table XV, Section V).
- b. Gamma Spectrometry Monthly samples were analyzed for gamma-emitting nuclides by spectro-metry of the total sample. Results of gamma spectrometric analysis of samples from both stations are given in Table XV, Section V. Be-7 was found in eight of twenty-two samples and was the result of cosmic ray activity. Due to their short half-life, concentrations of Zr-95, fib-95, Ru-103, Ce-141 and Ce-144 were attributed to fallout from the Chinese atmospheric nuclear weapon test of October 1980. Small con-centrations of Cs-137 and K-40 were detected and were attributed to world-wide fallout and natural background.
- 5. Air Particulates Continuous air particulate samples were collected from the on-site Peach Bottom Weather Station #1 (1Z) and from the intermediate lo-cation, Conowingo Dam (4A). (For station locations, see Figure 1 and 2, Section VI). The following analyses were performed on air particulate samples.
- a. Gross Beta Weekly samples were analyzed for concentrations of beta emitters.
Results of gross beta analysis of air particulate samples can be found in Table XVI, Section V. Samples collected from 12/27/80 to 7/26/81 generally showed higher gross beta activity than data col-lected during the remainder of the year. The activity was associated with continued fallout from the Chinese atmospheric nuclear weapon test of October,1980. These data wem similar for pmvious years when nuclear atmospheric weapons were tested (2).
- b. Gamma Spectrometry 1
Monthly composite samples were analyzed for gamma-emitting nuclides by gamma spectrometry. Results of gamma spectrometric analysis are given in Table XVII, Section V. Be-7 was detected in all 24 samples and was the result of cosmic ray activity. Several other nuclides 13 l j
E found (lin-54, Zr-95, fib-95, Ru-103, Ru-106, Cs-137, Ce-141 and Ce-144) were similar to those detected in previous years. These concentrations can be attributed to world-wide fallout from the Chinese atmospheric nuclear weapon test. Co-60 was detected at the minimum detectable level in one sample at the on-site station 1Z in flarch. Statistically l this activity could be zero. W
- 6. Air Iodine toni.inuous air samplers were collected at eight stations and analyzed weekly for I-131. Three stations (IB,12, 2) were located within the Site area. Four stations (3A, 5, 6B,14) were located at intermediate distances of 1.9 to 5.8 miles from the Site. One station (12D) was lo-cated 62 miles from the Site. Results of I-131 analysis can be found in Table XVIII, Section V. All results of the 405 analyses performed were less than the minimum detectable level.
- 7. liil k liilk was sampled at eleven farms; three farms (G, J and 0) located within two miles of PBAPS were designated "near farms"; four farms (D L, it and it) located 3 to 5 miles from PBAPS were designated as l
" intermediate farms"; and four farms (A, B, C and E) located greater a than five miles from PBAPS wem designated as " distant farms". The following analyses were performed on milk samples.
- a. Triti um 1111k from four farms (A, C, G and J) was analyzed for tritium concen-trations in the aqueous fraction on a quarterly basis. Results of tritium determinations in milk samples can be found in Table XIX, Section V. Concentrations detected were generally within the range l found during the Peach Bottom Units #2 and #3 preoperational period (1). E
- b. Iodine-131 g j
fiilk from eight farms (A, B, C, D, G, J, fl and 0) near Peach Bottom was ! analyzed for concentrations of I-131, monthly in January, February, liarch i and December. Weekly I-131 analyses resumed during the last week of liarch I and continued through the fourth week of flovember. Three additional farms (L, li and E) were sampled and analyzed quarterly for I-131. Results of I-131 analysis can be found in Tables XIX and XX, Section V and Figure 12, Section VI. All results were less than the minimum detectable level,
- c. Sr-89 & Sr-90 One milk sample was collected at farm J in each quarter and analyzed for I l Sr-89 and Sr-90. Results can be found in Table XIX, Section V. These concentrations were similar to those observed in previous years.
- d. Gamma Spectrometry One milk sample collected at farm J in each quarter was analyzed for gamma-emitting nuclides by gamma spectrometry. Results can be found 14 I

in Table XXI, Section V. fluclides detected wem naturally-occurring K-40 and Cs-137. Cesium-137 is commonly found in milk as a result of world-wide fallout.
- 8. Soil Semiannual samples were taken at three locations, one on-site station (2) and two distant stations (3A and 5) located about four miles away from PBAPS (for station locations, see Figums 1 and 2, Section VI).
t The ama at station 2 is heavily wooded with rock outcroppings. The I soil at this location would be expected to contain substantial humus from the accumulation of natural vegetative debris. Station 3A is covered only with grass. Station 5 is a conbination of grass and cultivated land. The following analyses were perforned on soil samples.
- a. Strontium-89 and Strontium-90 Samples from all stations were analyzed for Sr-89 and Sr-90 concentra-tions in the top one inch and bottom five inches separately. Resul ts of Sr-89 and Sr-90 analysis in soil samples can be found in Table XXII, Section V. Concentrations of Sr-89 were at or near the minimum detec-table level in all samples. Concentrations of Sr-90 detected were within the range found during the PBAPS Units #2 and #3 preoperational period (1). Graphical comparisons of Sr-90 in the top one inch and bottom cut can be found in Figures 13 and 14, Section VI. Di fferences between the on-site location (2) and distant locations (3A and 5) were attributed to the accumulation of vegetative debris at station 2.
- b. Gamma Spectrometry Samples from all stations were analyzed for gamma-emitting nuclides by Ge(L1) gamma spectrometry (Table XXIII, Section V). fluclides identified were generally the same as those found during the PBAPS Units #2 and #3 preoperational period.with most at the same or lower concentrations (1).
Some naturally-occurring nuclides wem found (K-40, Ra-226, Th-232). Small concentrations of Cs-137 were detected in all twelve samples. The 30 year half-life and biological assimilation of Cs-137 accounts for the continued appearance of this nuclide in soil samples many years after atmospheric testing of nuclear weapons. Diffemnces 'between the on-site location (2) and distant locations (3A and 5) wem attributed to the l accumulation of vegetative debris at station 2 (Figums 15 and 16,
} Section VI). Since no Cs-134 or ther Station related nuclides were found in any of these samples, the Cs-137 can be attributed to world-wide fallout.
- 9. Anbient Gamma Radiation Ambient gamma radiation levels wem measured with calcium sulfate:
Tm thermoluminescent dosineters. Thirteen stations (1B,1C, ID, IE, IF,1G,1H, IJ , IL, Ifi, Illfi, 2 and 40) were located around the Site boundary and designated for comparison pur-poses as the " site boundary ring". Twenty-five stations (3A, 4K, 5, 6B, 14,15,17, 22, 23, 26, 27, 31, 32, 33A, 38, 42, 43, 44, 45, 46, 47, 48, 15
I 49, 50 and 51) were located within a 10 mile radius of the Site and designated as the " middle ring". Seven stations (128,16,18,19, 20, 21B and 24) were located from 10 to 60 miles from the Site and designated as the " outer ring". Since they could be more directly affected by plant activities and do not represent doses to the pub- l lic, two stations (1A and II) located within the plant complex con- W stitute a fourth group called plant-complex stations (for station locations, see Figures 1, 2 and 3, Section VI). Results of TLD 3 measurements are listed in Tables XXIV, XXV and XXVI, Section V. 3 TLD data collected from 1/31/81 to 3/28/81 were generally higher than those from the remainder of the year. These data were simi-lar to other years and may be the result of increased activity from Radon gas migrating to the surface during a thaw. These data were within the range of the 95% confidence of the means indica-ting that the values observed were due to natural variation. The annual average of monthly and quarterly radiation levels were within the range found during the Peach Bottom Units #2 and #3 g preoperational period (1). Graphical comparisons of the site- g boundary, middle and outer rings on monthly and quarterly readings showed no significant differences in ambient radiation levels with distance from PBAPS, indicating no measurable Station contribution (Table XXVI, Section V, Figures 17 and 18, Section VI).
