l A. INTRODUCTION
+ A pre-operational environmental radioactivits surves, initiated in March 1960, was conducted b3 Nuclear Science &
Engineering Corporation for the Philadelphia Electric Companu in 1
connection with Peach Botton Atomic Power Station located in Peach Botton Township, York Counts, Pennss1vania. The initial loading of fuel into Unit 1, a 40 MWe (net) high tenperature, gas-cooled reactor, was started on Februars 5, 1966, and initial i
criticalits was achieved on March 3, 1966. Shutdown of Peach Botton Unit i for decommissioning was on October 31, 1974. For the purposes of this Monitoring progran, the beginning of the
, operational period for Unit 1 is Februaru 5, 1966. A sunnaru of the Unit 1 pre-operational nonitoring progran is presented in a previous report (1).
Peach Botton Units 2 and 3 are boiling water reactors each with a power output of approximatelu 1050 MHe (net). First fuel was loaded into Peach Botton Unit 2 on August 9, 1973, criticality was achieved on September 16, 1973, and full power was reached on June 16, 1974. The first fuel was loaded into
[ Peach Botton Unit 3 on Juls 5, August 7, 1974, criticalits was achieved on 1974, and full power was first reached on December 21, 1974. A pre-operational sunnaru report (2) for Units 2 and 3 has been issued previously and sunnarizes the results of all analyses performed on samples collected from Februaru 5, 1966 through August 8, 1973. Detailed progran description, station designation. reporting units, abbreviations, etc., are given in that report reflecting the program status at that time. Where changes had been made from the original progran, theu are indicated in the appropriate sections of that sear's report. In general, anu such changes have been nade to increase the scope and specificitu of the program to fulfill the progran objective and to reflect the latest reconnendations of various government agencies. These changes are detailed in previous reports.
' report sunnarizes the results of analuses performed by This Chemical Haste Management on samples representing the period January 1 through December 31, 1982 in the Chemical Haste
. Mananenent portion of the overall Peach Botton program.
The laborators responsibilitu for performance of the environmental radiation monitoring progran has been nodified several times since the Peach Botton Unit 1 pre-operational progran was first undertaken in 1960. Fron the start of the progran until the first quarter of 1969, a single laborators located in Pittsburgh, Pa., was used. This was initiallu called Nuclear Science and Engineering Corporation and later became Nuclear Science Division, International Chemical and Nuclear Corporation as a result of a change of ownership. During the first quarter of 1969, the program was transferred to
, PAGE 1 F- - --
ICN/Tracerlab, also part of the International Chemical and -
Nuclear Corporation and was performed bu ICN in the Halthan, Mass., laborators until the end of the first quarter of 1972.
At this time the program was transferred to Interex Corporation laboratories in Walthan. The Interex Corporation laborators was noved to Natick, Mass, in Mau 1974. Interex Corporation carried out sample collection, analusis and report preparation until j November 1981 when the laborators and certain other operatins I were purchased bu Chemical Waste Management, Inc., which is now performing these functions. During the various change-Overs and g naves, extreme care was taken to insure that continuits in all program was naintained. For example, j
aspects of the overall samples were collected by the same individual throughout the entire period.
The objective of this progran is to acquire quantitative data for the concentrations of radioactivitu in environnental media in the vicinits of the reactor site prior to and during operation of the reactor plant. These data are then exanined to determine the extent of the impact of the plant or plants on the environment as reflected bu any changes in the radioactivitu levels fron those observed during the pre-operational surveu.
Generallu, this is done by comparing the observed levels at those sampling stations which would be expected from various lg consideratons to show naximum effects of plant operation to levels at stations renote from the site. When possible, comparison is also made to data obtained bu various government 3 agencies. Since there are both natural and nan-made l tadioactivitu present in the environment which are not related to plant operation, it is important to understand and adequatelu measure these contributions.
A number of radioactive elements occur in nature. The most important of these are uranium and thorium, along wih their j respective radioactive decas products, and potassium-90 (K-40). l The concentrations of natural radioactivitu varu with geographical location and with time and are ; rinarils dependent on the concentration of the respective elements in the constituents of the lithosphere. Therefore, environmental radioactivitu measurements nust be performed at a number of locations representative of the general geographical area of interest.
Other radionuclides have been introduced into the biosphere as a result of the detonation of nuclear devices in the atmosphere. A significant fraction of these nuclides is generallu disseminated throughout the upper atmosphere with the fine particulate debris from the detonation. Varsing fractions the nuclear debris eventualls are deposited at ground level, "
of Principalls in conjunction with precipitation. After their arrival at ground level, the radionuclides enter soil or bodies j of water, and varuing fractions nau enter drinking water I supplies or be assimilated bu edible plants or animals and thus enter the human food chain. Natural radioactivities are also <
introduced into the hunan diet bu analogous processes.
PAGE 2
The deposition patterns of nuclear debris depend on manu <
factors including latitude, proximits to detonation sites, l annual accumulation of precipitation, and the frequencu, magnitude, location, and altitude of the detona tions. In the absence of detonations, seasonal variations have been noted for several uears, including naxinun depostion rates in the spring and sunner months and mininun rates in the late fall or earls winter. Distinct variations have also been noted in individual precipitations. These latter variations ha"e been attributed to variations of meteorological cor.ditions prevailing during the respective precipitation events.
Since significant geographical and temporal variations are expected in the concentrations of both natural and nan-made radioactivitu in environmental media, it is necessaru to acquire experimental values for their concentrations over a period of several uears to achieve statisticallu-significant data. Such an approach also provides data for seasonal or annual trends in the temporal behavior of these concentrations and permits correlations of these trends with neteorological or clinatological factors or with known injections of man-made radionuclides into the atmosphere.

SUMMARY
The environs radiation monitoring progran detected plant related radioactivitu at veru low levels in two sample tupes in Conowingo Pond. Cs-137, Cs-134 and Zn-65 were found in fish samples obtained from 4 locations. In addition, Co-58 and Co-60 were found in samples from two locations in the plant water diccharge susten. Silt samples at three locations showed Cs-137, Cs-134, Co-60 and Zn-65. The resulting doses to the maximum exposed individual were well below 10 CFR 50 Appendix I design objectives.
Samples such as soil, fish, etc, showed gross and/or net activities which are consistent with the known presence of naturally-occurring nuclides or which are nost probablu attributable to fallout from nuclear testing and therefore did not result from PBAPS operation.
There was no other measurable environmental radioactivits which is attributed to the operation of PBAPS.

I IV. DISCUSSION OF RESULTS The results obtained from the progran are presented in the data tables and figures following this section and are discussed below according to sample tupe. Results of analuses which are performed on ashed samples of food products are reported in units of PCi/s original sample in addition to PC,/g ash. This is done to enable one to more easily estinate doses to non bu reporting concentrations of radioactivits in food products, as determined by the radiation nonitoring program, in terns of the j sample state which is eaten b3 nan. The resuits reported in I these units, however, offer poorer comparisons of data because biological variables, such as water content, great 13 affect the results. Results reported as radioactivits concentrations in terns of the ashed weights eliminate these variables and put the 1 data on a more uniform basis for comparison. For this reason, I the graphs in this report which are intended to show comparisons of concentrations of radioactivits between locations and time periods illustrate data reported in terns of the ashed weight, not the original sample weight.
All results are given with an error corresponding to two standard deviations in the net count rate e:<cep t f or K-40 which
.i s gene: ellu 10% when significant13 above the detection limit.
Results which are less than the calculated error are reported as '
less than (<) the value corresponding to the error.
The heading " radioactive cesion" is used to indicate total radio-cesion which is the result from beta counting the radiochenicalls-separated cesio$ fraction. Where the nuclides ai. neasurer.? individua113 it is so indicated in the heading.
In calculating averages, results reported as "less than" a value are included as that value. The average of a series of numbers which contains at least one real number is given as a real nunber. If all of the numbers in a series to be averaged are "less than" numbers, the average value is given as a "less j than" value. The deviation listed with means is equal to two q standard deviations of the data comprising the mean.
In the discussion of data, general trends in ui.e data i. r e stressed as are comparisons of .esults from stations which would l nost lik .; be affected by Peach Botton Atomic Power Station (PBAPS) operation, with data from those which are more renote from the site. Because of the presence of generall3 lower levels of radioactivitu in the environnent compared to earlier periods of atnospheric nuclear testing, precise trends tend to becone obscured in the normal variabilits of data.
l PAGE 20
> A. AIR PARTICULATES The values of the concentrations of gross beta radioactivits observed in air particulate samples are listed in Tables IV.1.1
(- through IV.1.4 and are presented graphical 1s in Figures IV.1.1
( and IV.1.2. Ganna spectral anaisses are given in Table IV.1.5.-
For comparative purposes, stations have been divided into three groups. Group I, which is on the Peach Botton site and h closest to the plant release points, consists of Stations 1A, 1 8 ,: and 2. Group II rings the site at further distances and f consists of Stations 3A, 4B, 5, 68, 14, 15, 17, 31, 32, 33A, and L, 38. Group III, which is in Philadelphia, Pennsulvania serves as a reference group and consists of Stations 12A and 170.
( Gross beta radioactivits concentrations were genera 113 below 0.05 pCi/n3 throughout the sear. Values tended to be later in I
t the fall although the normal annual trend is becoming obs cured at. these low activits levels. The data are tspical of that seen h during the absence of recent nuclear testing.
As can be seen from Figures IV.1.1 and IV.1.2, there was no
[ significant difference between the values obtained for the three groups of stations indicating no effects due to PBAPS
~ operations.
( Figures IV.1.3, IV.1.4 and IV.1.5 are long tern plots comparing Peach Botton data with Environmental Protection Agencu (EPA) (5) data through 1978. The EPA data exhibit the same trerd
(. as the PBAPS data. Therefore, Harrisburg EPA data are no longer reported, effective with the 1979 report.
Figures IV.1.3 through IV,1.5 show comparable trends and values over the period 1966-1982 for all three groups of stations even though the composition of the groups has been
( changed In3 adding more sampling stations. This would indicate that the distribution of activits over the entire area is relativels uniform and is not affected by PBAPS.
Ganna spectrun measurements are made on monthlu conposite samples from each station. These samples generalls consist of
/ all weekly samples for the month from the given station taken
( together. Results of these analuses are given in Table IV.1.5.
Naturallu-occurring Be-7 was detected b3 GeLi ganna spectrometru i in the majorits of the samples as has been the case in the past.
No other nuclides were detected.
(
-No contribution from the operation of PBAPS is indicated.
B. PRECIPITATION The concentrations and surface densities of gross beta, Sr-89, Sr-90, and Cesion radioactivits in precipitation simples collected at Stations 1A, 18, and 4M are presented in lables IV.2.1 and IV.2.2.
PAGE 21 F -
Most of the radioactivitu in precipitation samples is in the form of particulates which are washed out of the air bu rainfall and collected in sample containers. Since nost of the particulate material ~is washed out in the initial part of a rainfall, the surface densits, i.e., PCi/m2, is used in addition to concentration (pCi/1), .because it tends to minimize the effect of sample volune. Lack of complete correlation with air particulate- values comes about because rainfall generallu does not occur at frequent intervals. The dependence of the activity levels on the precise conditions occurring at the start of each rainfall can cause wide variablits between samples even when taken over limited geographical areas.
Gross beta radioactivits concentrations in individual month 13 samples ranged from a few to approximatelu 30 pCi/1.
' Corresponding surface densities were mainly in the low hundreds of PCi/m2. There did not appear to be ans discernible difference between locations. The values observed were similar to those seen in earlier sears and are in the range of preoperational data.
The values of Monthls gross beta radioact ivits concentrations observed in the precipitation samples collected at Station 4M are similar to those from comparable samples from Stations 1A and 1B except that theu are general 19 slightly lower when compared as pCi/n2. This has been the case since 1974 and was seen in several seats during the pre-operational period.
Sr-89 radioactivits was barels detected in one of the l- samples from Station 4M. This is most likels due to counting
! statistics.
Sr-90 radioactivitu concentrations where measurable were generallu a few tenths of a pCi/1. Surface densities were general 19 in the low tens of PCi/n2. These levels are comparable i to what has been observed in previous periods when there was no nuclear testing.
i
! Cesium radioactivits concentrations and surface densities at Stations 1A, 1B, and 4M as given in Tables IV.2.1 and IV.2.2 are generalls undetectable to a few tenths of a PCi/1. Corresponding surface densits ranged up to approximate 13 60 PCi/m2.
The observed radioactivitu concentrations at Station 1A, 18, and 4M show the variabilits tupical of precipitation and collectively do not indicate anu contribution from the operation of PBAPS.
C. SURFACE WATER AND DISCHARGE WATER The concentrations of gross alpha and gross beta radioactivits in the soluble and insoluble fractions of surface water and discharge water grab samples are given in Tables IV.3.1 and IV.3.3. Similar values for the composite samples fron l
PAGE 22
Stations 1LL, 1MM, SL and 6I are given in Tables IV.3.2 and IV.3.4. Mean radioactivitu concentrations are given in Tables IV.3.1 through IV.3.4. Comparative monthly and annual values are presented in Figures IV.3.1 through IV.3.6.
( The reporting unit for the insoluble fractions is PCi/9 ash which is intended to mininize the effect of varuing amounts of insoluble material in the samples.
{ Gross alpha radioactivitu was found in the soluble fraction of a few samples at or slightly above the detection limit. The
? gross alpha radioactivitu concentrations in the insoluble fraction were generalls in the range of 30 to 60 PCi/s ash.
These values are consistent with those seen in 1981, the onlu previous period for which this unit was used.
Data for gross beta radioactivitu concentration in surface water and discharge water samples are shown in Figures IV.3.1
( through IV.3.6. The values obtained for the soluble fraction were generally between the lower detection limit of approximatelu 2 pCi/1 and 5 pCi/1. A few results were slightlu
( higher. Results for the insoluble fraction were usualls in the L range of 40 to 70 pCi/g ash comparable to or slightlu lower than seen in 1981. Occasional high values, e.g. 500 +/- 100 pCi/o ash j as seen at location SL, occur when the amount of solids in the sample is small.
[
Comparison of both gross alpha and gross beta radioactivitu concentrations shows no significant differences between grab
{ samples and composite samples.
( The similaritu of results among stations shows no indication of anu measurable radioactivitu in receiving water bodies due to the operation of PBAPS during the period of this report.
e l D. WELL HATER s
Results of the analusis of well water samples for gross E alpha, gross beta, Sr-09, St-90, and Cesium radioactivitu and uranium are given in Table IV.4.1.
Radioactivits in well water samples generalls arises from y the leaching of naturallu-occurring nuclides from the rocks and soil past which the water flows. As levels of the water table j changes, variations can be encountered in the flow pattern I followed bu the water in a given well. This can cause changes in the radioactivitu content of the water s: nr.e the leachability of the radioactivity varies as the permeabilitu of the soil and (L rock encountered bu the water differs. An additional factor which can change radioactivitu concentration is the well usage.
A well which is used at a constant rate tends to maintain a more constant radioactivitu level. Lack of usage can cause buildup of radioactivity concentration if conditions vers close to the well are anenable to leaching, or it can cause concentrations to
[ PAGE 23
decrease if water from the naJor sources of the radioactivity does not reach the well when samples are taken.
Gross . alpha radioactivits concentrations were genera 113 found to be below the detection limit of several tenths of a pCi/1. This is consistent with data from the Units 2 and 3 preoperational period.
A few of the gross beta values were above the detection limit of 2 pCi/1. The measured values were in the range of 2 - 4 pCi/1.
Uranium was below the detection limit in all samples from both on-site and off-site locations. The levels in general are similar to or below those seen in previous periods. Uranium is natura113-occurring in nost rocks and is not of plant origin.
No Sr-89 radioactivits was detected in ans of the samples.
Sr-90 was measured at the detectior. limit of 0.3 pCi/1 in one sample from a renote location.
Cesium was measured in two samples near the detection limit of 0.4 pCi/1..This is probablu due to counting statistics.
Mean values as given in Table IV.4.1 show no significant differences between wells close to or on site and those at distant locations indicating no measureable radioactivits from the operation of PBAPS.
E. SOIL The results obtained for concentrations of acid-leachable stoss beta, K-40, net beta, St-90, Sr-89, and Cesion radioactivits in soil samples are given in Table IV. 5.1. Mean values for St-90, Sr-89 and Cesium are plotted in Figures IV.
5.1 through IV. 5.3.
Alpha and beta radioactivitu are found in soil samples because of the presence of natural 19-occurring nuclides in the uranium and thorium series and K-40, and from nuclides present in fallout from atmospheric nuclear weapons testing. Specific analusis for Sr-89, Sr-90 and Cesium, which are normal 19 present in fallout, are done to measure these nuclides in the presence of the larger quantities of natural 19-occurring radioactivits.
Net beta radioactivitu, which was detectable in the majorits of the samples. ranged from 1 to 10 pCi/g dru weight. Most of the results were below 5 pCi/g dru weight. This is within the range of normal variabilits.
The majorits of the Sr-90 concentrations were grouped in are approximate range of a few tenths of a pCi/9 dry weight. All of the values are consistent with previous annual averages.
. St-89 concentration was measured above the detection limit in two samples, one from a distant location.
PAGE 24
The concentration of Cesion genera 113 was a few tenths of a pCi/g dru weight and measurable in all samples. All values were within the range of preoperational data. Samples from Station 6G genera 113 showed the higher values.
( Values obtained from samples taken at the Peach Botton site are comparable to the average values from the surrounding sampling stations. Overall there is no indication of measurable f' radioactivits in soil from PBAPS operation.
F. SILT H
Table IV.6.1 gives the analutical results and annual neous for concentrations of acid-leachable gross alpha, gross beta, Sr-89, Sr-90 and Cesium radioactivitu for silt samples. GeLi sanna spectron analusis results are given in Table IV.6.2. Gross beta and specific nuclide activities observed at several stations are presented in Figures IV.6.1 through IV.6.4.
( Silt samples are expected to contain natura113-occurring radioactivity, as discussed above for soil samples, in addition to ans other activits introduced into the aquatic environment
{ which would settle onto or be absorbed b3 the silt. As car. be seen bu comparison of the data in Tables IV.5.1 and IV.6.1, the activitu levels in silt genera 113 are similar to those found in soil.
r The concentrations of gross alpha radioactivits at all sampling stations was genera 113 a few PCi/9 dru weight and are
{- well within the range of variabilits observed in PBAPS Units 2 and 3 preoperational period.
Gross beta radioactivitu concentration was comparable to the gross alpha concentration. The results and variations between stations are consistent with the PBAPS Units 2 and 3 preoperational period.
Sr-90 concentrations occurred within the approximate range
.of 0.01 to 0.05 pCi/9 continuing the lower trend seen in 1981.
{ All results are within the range of variabilits observed during the PBAPS Units 2 and 3 preoperational period.
St-89 was found in two of the samples at the detection limit. This is probablu due to counting statistics.
i
( Samples analuzed showed Cesiun genera 113 at low levels of a few hundredths to a few tenths of a pCi/9 dru weight which is well within the range of PBAPS preoperational data. Anu apparent discrepancu between the radio-chenistru values and ganna
{. spectrum values most probablu occurs because the ganna spectrun values given in Table IV.6.2 are more representative of the
( whole sample, which is inhomogenious, rather than onlu the
( aliquot analuzed. The differences between stations are discussed below under sanna spectrum analusis.
PAGE 25
Figures IV.6.1 and IV.6.2 compare Stations 4D, 4J and 4T which are at increasing distances from the PBAPS discharge.
There does not appear to be ans consistent correlation of the observed levels with particular locations when normal variabilits is taken into account. The preoperational data show approximate 1s the same spread in values and values of similar magnitude to those seen during this period. The observance of Cs-134 at several of the locations is discussed below.
Station 1BB, in the discharge canal down-flow the liquid rad-waste discharge, and Station 6F, above Holtwood Dan, are compared in Figures IV. 6.3 and IV. 6.4. Figure 6.3 indicates no positive addition of Sr-90 radioactivits bs PDAPS operation, when normal variabilits is taken into acccont. The concentrations of radioactive Cs as shown in Figure IV. 6.4 indicate higher levels at Station 188, consistent with the sanna spectrum data.
Ganna spectrum analysis showed primarils the presence of K-40 and the U, Th series as represented bs Ra-226 and Th-228 respectivels all of which are natural 19-occurring, and Cs-137.
Cs-134, Co-60 and 2n-65 were found in the fall samples from Stations 1BB, SD and SJ and are most likels from PBAPS operation because thes are reactor-generated products. Co-60 and Zn-65 were also found in the fall sample fron Station 1X. There was no detectable Cs-134 at Station 1X.
The overall similarits of results between locations and with the preoperational data indicates no addition of radioactivitu due to the operation of PBAPS except for vers small concentrations of Cs-134, Cs-137, Zn-65 and Co-60. If it is assumed that all Cesium, Co-60 and Zn-65 found at off-site locations is due to PBAPS releases, a dose calculation using the USNRC Regulators Guide 1.109 Model and assumptions results in a
- ccleulated dose of 7.06 E-3 mren to a teenager's skin. This calculation conservative 19 assumes that the teenager was exposed to the maximun concentrations found for the entire exposure period.
G. FISH The results of the ana19 sis of fish sanples for concentrations of gross beta, K-40, net beta, Sr-89 and SP-90 radioactivits are given in Tables IV.7.1 and IV.7.2. Ganna spectrum data are presented in Table IUe7.3. Mean values are Presented in Tables IV.7.1, IV.7.2, IV.7.4, and IV.7.5. Sr-90 concentrations are plotted in Figure IV.7.1.
Net beta radioactivits generalls ransed fron <.10 to 30 pCi/o ash with an average of about 10 pCi/9 ash. The values were well within the range of PBAPS preoperational data.

l Radiostrontium analysis was resuneu on a temporary basis during the second halt of 1979 and continued through 1982 b e c 7. e e: e nf t.he possibilitu of release of Sr-89 and Sr-90 from a source upstrean from the Peach Botton site.
t Sr-89 was barels detectable in a few of the samples at a few
( tenths of a PCi/g ash.
Sr-90 radioactivitu concentration as determined in samples from all locations was generally several tenths to 1 pCi/g ash corresponding to several hundredths of a pCi/g original sample, f
Stations 1EE and 4J, as a group of stations which could be affected b3 PBAPS operation, and Station 6H which is above Holtwood Dan and therefore unaffected bu PBAPS, are compared in Figure IV.7.1. There is essentia113 no difference in the range of concentrations for Sr-90 radioactivity in fish from these locations.
Ganna spectron analyses as shown in Table IV.7.3 genera 113 indicates the presence of onlu naturally-occurring K-40 and Cs-137 from atmospheric nuclear weapons test fallout. Cs-134 and
(: Zn-65, most probablu from PBAPS, were found in several samples Pond as well as in samples from the plant water from Conowingo discharge susten. These nuclides were found at Stations 1EE, 1X, 4I and 4J. In addition, Co-60 and Co-58 were found in samples fron Stations 1EE and 1X. These locations are in the plant water discharge susten.
Exanination of data indicates essentia113 no difference other than nornal variabilits between off-site stations for all nuclides except Cs-134 and Zn-65. The maxinun dose calculated using the USNRC Regulator 3 Guide 1.109 model and assumptions is 3.69 E-01 nren to a teenager's liver. The actual dose due to PBAPS operations is noch less than that since on13 some fish were found to contain Zn-65 and Cs-134 and Cs-137 is present at all stations fran sources other than PBAPS.
H. VEGETATION P
concentrations of gross beta, net beta, M-40, St-89,
[ Sr-90, The and Cesion radioactivits are given in Tables IV.8.1 and IV.8.2 for vegetation samples. Mean values are in Tables IV.8.1 and IV.8.2. Fiqures IV.8.1 and IV.8.2 show annual mean values
{ for Sr-90 and Cesion radioactivitu concentrations.
The concentrations of net beta radioactivits are s.inilar for
[ all stations and appear to haw approximate 13 the same spread.
ranged from about 20 to 120 pCi/9 ash. All M e a si..ir a b u values results are in the range measured during the PBAPS Units 2 and 3 preoperational period. Corresponding values were in the general range of several tenths to about 3 pCi/9 original sample. The raw ueight to ashed weight ratio varies narked 13 between samples PAGE 27
r as would be expected from the different water content of various types of vegetables and vegetation.
Measurable Sr-90 radioactivits concentrations had a range from about 1 to approximate 19 30 pCi/s ash with the majorits of values between 1 and 10 pCi/g ash. Wild vegetation tended to
-have higher values probablu due to greater accumulation of fallout because of the longer growing season. The higher values for apple samples from Station 23 are probablu due to the high water content, since the values are not high when compared on a pCi/g original sample basis. These concentrations are well within the range of PBAPS preoperational data. The corresponding values in terns of PCi/g original sample showed a similar range from a few hundredths to a few tenths of a pCi/9 The annual mean values shown in Figure IV.8.1 differ b3 approximately a factor of 2. This difference disappears when the values are compared on a pCi/g original sample basis.
[
t St-89 was detected in several samples possiblu due to residual debris from the Chinese test in October of 1980. This could also be due to counting statistics, since there is a relative 13 large amount of Sr-90 present.
Cesiun radioactivitu was generally measured at concentrations from a few tenths to a few PCi/s ash. The higher values again tended to be seen at remote Station 3A. The corresponding average values were a several thousandths to a few hundredths of a pCi/a original sample similar to previous values. The annual mean values shown in Figure IV.8.2 are comparable to each other.
There is no indication of a contribution to the radioactivitu in vegetation from the operation of PBAPS.
I. MILK The concentrations of gross beta, K-40, net beta, Sr-89, Sr-90, Cs-134, Cs-137, and I-131 radioactivits are given in Table .IV.9.1 Mean values are presented in Tables IV 9.1 and IV 9.2. Mean concentrations of Sr-90, Cs-137, and I-131 are plotted in Figures IV.9.1 through IV.9.3.
For purposes of data comparison, farms have been divided into three groups one containing Farns G, J, and 0, which are regional farns near the Peach Botton site; a second consisting of Farms A, B, C and E, which encircle the Peach Botton site at remote distances; and a third consisting of Farms D, L, M, and N, which are at intermediate distances from the Peach Botton site.
-The concentration of net beta radioactivits genera 113 ranges from undetectable to a few hundred PCi/1 as has been the case .
during and since the preoperational period. The major beta activits in milk is due to the presence of natura113-occurring K-40 at concentrations of approximatels 900 pCi/1. The residual PAGE 28
l net beta values are most probably the result of the difference between two tupes of measurements and are not real. The gross
(. beta radioactivity is measured direct 13 on milk ash while the K-40 value is calculated from chemical measurement of potassion
[ on dissolved ash. From the known Metabolic process of cows, it L is unlike19 that anu radioactive nuclides from a nuclear power plant other than those of strontium, cesium, barium-lanthanun, h3drogen or iodine would be present in milk. The low values for gross beta and K-40 radioactivits concentrations in some of the Julu samples is apparently a sustematic analutical error related to the ashing procedure.
F The Sr-90 radioactivitu concentration for all farms was in the range of about 2 to 7 pCi/1. This range is similar to the ranges for 1975 through 1981. These concentrations are well within the range of PBAPS preoperational data.
j The annual mean values of Sr-90 for each farn group as shown in Figure IV.9.1 generalls lie between 3 and 5 PCi/1 and do not
[ show ans consistent difference between groups. The overall values are similar to those obtained during the PBAPS Units 2 and 3 preoperational period.
Sr-89 was found in a three of the samples at the detection
/ limit, most likels due to counting statistics.
1 Measurable values for Cs-137 radioactivitu concentration range from about 3 to 13 pCi/1, similar to the range seen l earlier. No significant difference was observed among the three farn groups as can be seen from Figure IV.9.2. The results are similar to those measured during Units 2 and 3 preoperational
' period, s
Cs-134 was not detected in anu samples. The absence of
- Cs-134 indicates that the Cs-137 is due to atmospheric nuclear
- weapons testing.
~
1-131 radioactivitu concentration results, corrected for decas to date of sampling, are presented in Table IV.9.1. I-131 not detected in any of the samples analyzed.
None of the samples contained radioactivity which can be s attributed to the operation of PBAPS.

- J. RABBITS Tables IV. 10.1 through IV. 10.2 present the ana13tical data and mean values obtained from the analysis for gross beta, K-40, and net beta radioactivity concentrations in rabbit bone, soft tissue, and Muscle, and Sr-89 and Sr-90 in bone. Iodine-131 concentrations in rabbit thuroids are also given. Quarterls mean values for net beta and Sr-90 radioactivits concentrations are shown in Figures IV. 10.1 and IV. 10.2.
PAGE 29
Measureable net beta radioactivitu concentration in muscle and soft tissue ranged from 30 to 60 pCi/g ash indicating again that the majorits of the activity is due to K-40. Corrneunding values are about a factor of 100 lower as pCi/g original sample.
For bone, values genera 113 ranged from <10 to 20 pC,i/9 ash decreasing by a factor of 2-5 as pCi/9 original sample. These values are consistent with the values seen during the PBAPS Units 2 and 3 preoperational period.
Sr A? 0 radioactivits values in bone ranged from about 4 to 13 l pCi/o ash similar to the range seen in previous periods. The l pCi/g original sample values are a factor of 3-7 lower.
Sr-89 was not detected in any of the bone samples.
1-131 was measurable in one of the thuroids analuzed, probably due to counting statistics. The relative 13 high value la and error are the result of decas between time of collection and time of analysis.
There is no indication of radioactivits in rabbits which can be attributed to operation of PBAPS.
