SUMMARY

( A. INTRODUCTION A pre-operational environmental radioactivitu

surveu,

/. initiated in March

1960, was conducted bu Nuclear Seit-nce &

L Engineering Corporation for the Philadelphia Electric Compans in connection with Peach Botton Atomic Power Station located in Peach Botton Township, York Counts, Pennsulvania. The initial ( loading of fuel into Unit 1, a 40 MWe (net) high temperature, gas-cooled reactor, was started on Februaru 5, 1966, and initial 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 nonitoring progran, the beginning of the operational period for Unit 1 is Februaru 5, 1966. A sunnars 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 MWe (net). First fuel was loaded into Peach Botton Unit 2 on August 9,

1973, criticalits 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 Julu 5, 1974, criticalitu was achieved on August 7, 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 previouslu and sunnarizes the results of all analuses performed on samples collected fron Februars 5, 1966 through August 8, 1973. Detailed progran description, station ( designation, reporting units, abbreviations, etc., are given in I that report reflecting.the progran status at that time. Where changes had been made from the original program, thou are indicated in the appropriate sections of that sear's report. In

general, ans such changes have been made to increase the scope and specificitu of the progran to fulfill the progran objective and to reflect the latest reconnendations of various government

( agencies. These changes are detailed in previous reports. This report sunnarizes the results of analuses performed bu ( Chemical Waste Management on samples representing the period Januaru 1 through December 31, 1983 in the Chemical Waste Management portion of the overall Peach Botton prouran. The 1,borators responsibilitu for performance of the environmental radiation monitoring program has been nodified / several times since the Peach Cotton Unit 1 pre-operational ( program was first undertaken in 1960. From the start of the progran until the first quarter of 1969, a single laboratoru located in Pittsburgh, Pa., was used. This was initial 19 called ( Nuclear Science and Engineering Corporation and later became ( PAGE 1 f

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 ICN/Tracerlab, also part of the International Chemical and Nuclear Corporation and was performed bu ICN in the Walthan, 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 Interen Corporation laborators was noved to Natick, Mass. in May 1974. Interex Corporation carried out sample collection, anslusis and report preparation until l November 1981 when the laborators and certain other operatins I were purchased bu Chemical Waste Management, Inc., which is rtow performing these functions. During the various change-overs and

noves, extrene care was taken to insure that continuitu in all aspects of the overall progran was maintained.

The objective of this progran is to acquire quantitative data for the concentrations of radioactivits in environmental media in the vicinits of the reactor site prior to and during l Operation of the reactor plant. These data are then exanined to determine the extent of the impact of the plant or plants on the i ervironment as reflected bu ans changes in the radioactivitu levels from those observed during the pre-operational surves. General 19, this is done bu comparing the observed levels at those sampling stations which would be expected from various consideratons to show naxinun effects of plant operation to levels at stations remote from the site. When possible, comparison is also made to data obtained by varios..is government agencies. Since there are both naturel and nan-nade radioactivi+,3 present in the environment which are not related l to plant operation, it in important to understand and adequatelu i neasure these contributions. A number of radioactive elements occur in nature. The most important of these are uranium and thorium, along wih their respective radioactive decau products, and potassium-40 (K-40). The concentrations of natural radioactivitu varu with geographical location and with time and are primarils dependent on the concentration of the respective elements in the constituents of the lithosphere. Therefore, environmental radioactivitu measurements must 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 nucliden is generallu disseminated throughout the upper atmosphere with the fine particulate debris from the detonation. Varsing fractions of the nuclear debris eventuallu are deposited at ground level, principalls in conjunct, ion with precipitation. After their arrival at ground level, the radionuclides enter soil or bodies P E.E 2

^ L { of

water, and varsing fractions nas enter drinking water supplies or be assimilated bs edible plants or animals and thus enter the human food chain. Natural radioactivities are also introduced into the human diet by analogous processes.

The deposition patterns of nuclear debris depend on nans factors including

latitude, proximits to detonation

sites, f

annual accumulation of precipitation, and the frequencu, magnitude,

location, and altitude of the detonations.

In the absence of detonations, seasonal variations have~been noted for { several

sears, including naxinun depostion rates in the spring and sonner nonths and Mininun rates in the late fall or early winter.

Distinct variations have also been noted in individual y precipitations. These latter variations have been attributed to ( variations of Meteorological conditions prevailing during the respective precipitation events. ( Since significant. geographical and temporal variations are expected in the concentrations of both natural and man-made radioactivits in environmental media, it is necessaru to acquire ( experimental values for their concentrations over a period of ( several sears to achieve statistica113-significant data. Such an approach also provides data for seasonal or annual trends in the temporal behavior of these concentrations and permits ] ( l correlations of these trends with neteorological or clinatological factors or with known injections of man-made radionuclides into the atmosphere. l l B.

SUMMARY

l Except for fish and silt samples no measurable anovnts of radioactivits were found offsite bu the environs radiation y monitoring progran which could be attributed to the operation of ( PBAPS. The progran detected plant related radioactivitu at vers low levels in two sanple tupes in Conowingo Pond. Cs-137, Cs-134, Zn-65, Co-60, Mn-59, and Cr-51 were found in fish ( sanples from offsite locations. Slight 13 higher concentrations of these nuclides were found in samples from the plant water discharge susten. Silt samples at five locations showed Cs-137, ( Cs-134, Co-60 and Zn-65. The resulting doses to the maxinun 5 exposed individual were well below 10 CFR 50 Appendix I design objectives. ( Sanples such as soil, vegetation, etc, showed gross and/or not activities which are consistent with the known presence of natura113-occurring nuclides or which are most probablu ( attributable to fallout from nuclear testing and therefore did not result from PBAPS operation. (. There was no other measurable environmental radioactivitu which is attributed to the operation of PBAPS. PAGE 3

l l 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 type. Resultu of analuses which are performed on ashed samples of food products are reported in units of PC1/9 original sample in addition t.o PCi/u ash. This is l done to enable one to more easily estimate dosen to man bu l. reporting concentrations of radioactivitu in food prosivetn, as deternined bu the radiation monitoring progran, in terns of the sample state which is eaten bu nan. The results reported ire these

units, however, offer poorer comparisons of data becaune biological variablen, such an water content,, geently affect the results.

Results reported as radioactivitu concentrations in ternu of the ashed weights olininate theue vartables and put, the data on a more uniform banis for conpartuon. For this reason, the graphs in thin report which are intended to show comparisons of concentrations of radioactivitu between locations and time periods illustrate data reported in torno of the auhed weight, not the original nonple weight. All results are ulven with an error correspondinq to two standard deviations in the not courit rate oncep t for K-40 which is general 19 10% when uinnificarillu above the detection lintt. Requit,s which are tens than t,he calculated error are reported an lean than (<> the value corrouponding

t (m h p A.: AIR'PARTICULATES ? The values of the concentrations of gross' beta;radioactivits observe.d in air particulate samples are listed in Tables IV.1.1 through.IV.1.4 and are presented graphicalls in Figures IV.1.'1 f; 3and IV.1.2. Ganna spectral analuses are given in'-Table IV.1.5'. ForL comparative

purposes, stations have been divide'd into

~ (:' three groups.- Group I, whichfis'en the Peach Botton site and closest 'to :the ' plant release points, consists of Stations 1A, . ilB,' and 2.- . Group II rings the site at further distances'and consists of Stations-3A,-48, 5, 6B, 14, 15, 17, 31, 32, 33A, and J l 38. - Group;III, which isiin Philadelphia,,Pennsulvania serves as a reference group and' consists of Stations 12A and 12D. ( Gross beta radioactivitu concentrations were generally below 0.05-.pCi/m3.throughout the sear. Values-tended to be lower in I ~ ~ the. fall-although the normal annual-trend is-becoming obscured at these low activitu levels. Variabilits:between weeks appears [o to be related to precipitation, which scavenges particulates from the air. The data are typical,of those seen during the absence of recent nuclear testing. 'As can be seen fron= 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 sane trend as the PBAPS data. Therefore, Harrisburg EPA data are no longer h reported, effective with the 1979 report. Figures IV.1.3 through IV.1.5 show comparable trends and ( values over the period 1966-1983 for all three groups of stations-even though the composition-of.the groups has been -changed by adding more sanpling s t a t i'ons. This would' indicate that the distribution of activits over the entire area is [E relativels uniform and is not affected by PBAPS. L Ganna-spectrun neasurenents are-nade on monthlu composite h samples'Tfrom each station. These samples generally consist of tall. Weeklu samples for the month from the'given station taken together. Results of these analuses are given in' Table IV.1.5. {E _Naturalls-occurring Be-7 was detected bu GeLi ganna spectronetru f: ('idsthe majority of the' samples as has been the case in the past. -Naturallu-occut'r'ing K-40.~was neasured at the detection limit in f7 two<. samples...No other nuclides were present above the nininum detectable level.. n T .b 9 4, g p. I g

No contiibutionzfrom the operation of PBAPS is indicated. B.-PRECIPITATION ~ The' concentrations and~ surface' densities of gross beta, JSr-99, Sr"90, and. Cesium-radioactivits in-precipitation samples-collected at. Stations 1A, 1B,.and 4M are presented.in Tables-IV;2.11and IV.2.2. Most.of-theradioactivits in precipitation samples is in the forn-of particulates which are-washed out of the air tn3 rainfall ~ and. collected . in. sample ; containers. Since. Most of the-Particulate-Material is ' washed out.in the' initial'part of a rainfall, the surface densits,,i.e., PCi/n2,.is used in' addition ] to. concentration (pCi/1), because -it tends.to minimize the effect of sample volume. Lack of complete correlation'with air-

particulate values comes about because. rainfall general 19 does

-not occur at frequent intervals. The dependence of the activits. _] levels-on the precise conditions occurring at the start of each J rainfall can cause wide variablity between samples even when taken over. limited geographical areas. Similar to air particulate values,= the gross beta radioactivits concentrations in precipitation samples collected at Stations 1A and 1B did not show anu spring increase that was tspical of previous sear's data.' Individual monthly samples ranged from undetectable to approximatels 10 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 radioactivitu concentrations observed in-the precipitation samples collected } at Station 4M are similar to those from comparable samples from Stations 1A and 1B except that thes are generalls slightly lower wnen compared as PCi/M2. This has been the case since 197.4 and was seen in several seats during the pre-operational period. No St-89 radioactivits was found in anu of the samples. ] Sr-90 radioactivitu concentrations where measurable were generalls a few tenths of a pCi/1. Surface densities,were . general 13 in the tens of PCi/n2. These levels are comparable to what-has' been -observed in previous periods when there was no' nuclear testing. -Cesium radioactivitu concentrations and surface densities at Stations 1A,.-1B, and 4M were -generalls undetectable to 1.4 pCi/1. Corresponding surface densitu ranged up to 80 pCi/m2. The detectable values were found at Stations 1A and 1B for the ); ~ PAGE 22 s

r . period icf. Mau 15, 1983 to October 1, 1983. Due to -the L unpredictable. nature of precipitation and linlited data available it. is-not possible to correlate the Cesiun .radioactivitu with PBAPS operation.

g. _

The observed radioactivitu-concentrations at Station 1A, 18, and 4M show the 'variabilitu tupical of precipitation and f: collectivels do not indicate anu contribution from the operation b~ of PBAPS. p C.; SURFACE WATER AND DISCHARGE WATER k .The concentrations of gross alpha and gross beta radioactivitu in the soluble and insoluble fractions of surface (.' IV.3.1 and IV.3.3. Similar values for the composite samples fron water and discharge water grab samples are given in Tables . Stations 1LL,.

1MM, 4L and 6I are given in Tables IV.3.2 and r~

IV.3.4. Mean radioactivitu concentrations are given in Tables L. IV.3.1 through. IV.3.4. Comparative month 19 and annual values are presented in Figures IV.3.1 through IV.3.6. h. The reporting unit for the insoluble fractions is pCi/g ash which is intended to mininize the effect of varuing amounts of insoluble material in the samples. [ Gross alpha radioactivitu was generallu undetectable in the soluble fraction. The gross alpha radioactivitu concentrations in the insoluble fraction were genera 113 in the range of 20 to 40 pCi/9 ash. The high value of 90 pCi/g ash was found at a reference Station 6A and resulted from the small weight. These values are consistent with those seen since 1901, the initial f period'for the use of this unit. Data for gross beta radioactivitu concentration in surface [ water and discharge water samples are shown in Figures IV.3.1 through 1U.3.6. The values obtained for the soluble fraction were genera 113 between the lower detection limit of approximat elu 2 PCi/1 and 5 pCi/1. Results for the insoluble (. - fraction were usualls in the range of 40 to 100 PCi/g ash conparable. to or slightlu lower than seen in earlier periods. Occasional high

values, e.g.

600 +/- 500 PCi/9 ash as-seen at h -location 61, occur when the amount of solids in the sample is snell. As shown in Figure IV,3.2, the insoluble gross beta radioactivitu concentration at Station 1MM averaged approximatelu twice that of Station'1LL. Comparison of the data ( shows a statistica113 significant difference (P<.01) between the L stations. Nn significant differences between arab sanples and h composite samples were observed in the gross alpha and gross beta radioactivitu concentrations. E' PAGE 23 f..~............

The similarits of_results among stations shows no indication of' ans neasurable radioactivits other than insoluble gross beta radioactivits in receiving water bodies due to the operation of PBAPS during the period of this report. D. HELL HATER Results. of the analssis of well water' samples for gross

alpha, gross

beta, Sr-89, Sr-90, Cesium radioactivits, and uranium are given in Table IV.4.1.

Radioactivits in well water samples generalls arises fron ] the leaching of natura113-occurring nuclides from the rocks and- .r soil past which the water flows. As levels of the water table

changes, variations can be encountered in the flow pattern

] followed bs the water in a given well. This can cause changes in J the radioactivits. content of the water since the leachabilits of the radioactivits varies as the permeabilits of the soil and ) rock encountered bs the water differs. An additional factor which can change radioactivits concentration is the well usage. A well whien is used at a constant rate tends to maintain a more constant radioactivits level. Lack of usage can cause buildup of radioactivits concentration if conditions vers close to the well are amenable to

leaching, or it can cause concentrations to

' decrease if water from the naJor sources of the radioactivits does not reach the well when samples are taken. Gross alpha radioactivits concentrations were generalls 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 - 7 pCi/1, Uranium was detectable in the majorits of the samples. The highest value of 1.64 u9/1 was found at an off-site location. The levels in general are somewhat higher than those seen in previous periods. This nas be due to the higher-than-normal rainfall experienced bs the region during 1983. Uranion is naturalls-occurring in nost rocks and is not of plant origin. No St-89 radioactivits was detected in ans of the samples. Sr-90 was measured in several samples up to 1.3 pCi/1. Cesium was measured in one sample at the detection limit of 0.2 pCi/1. This is probably 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 fron ] the operation of PBAPS.

4 ( E. SOIL The results obtained for concentrations of acid-leachable f gross

beta, K-40, net

beta, Sr-90, Sr-89, and Cesium radioactivits in soil samples are given in Table IV. 5.1.

Mean values for Sr-90, St-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 naturalls-occurring nuclides in the ( uranium and thorium series and K-40, and from nuclides present in fallout from atmospheric nuclear weapons testing. Specific analssis for Sr-89, St-90 7nd Cesium, which are normal 19 present k in

fallout, are done to measure these nuclides in the presence of the larger quantities of naturalls-occurring radioactivits.

( Net beta radioactivits, which was detectable in the majorits i of the sanPles, ranged from 1 to 6 pCi/9 dru weight. Most of the results were below 5 pCi/g dru weight. This is within the range of normal variabilits. The majoritu of the Sr-90 concentrations were grouped in an approximate range of a few tenths of a PCi/g dru weight. All of ( the values are consistent with previous annual averages. Sr-89 concentration was neasured slightlu above the { detection limit in one

sample, Probabl3 due to counting statistics.

( The concentration of Cesium generalls was a few tenths to l several PCi/g dru weight and ieasurable in all samples. All values were within the range of preoperational data. h 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 neasurable 1 ( radioactivitu in soil from PBAPS operation. F. SILT Table IV.6.1 gives the analutical results and annual means for concentrations of acid-leachable gross alpha, gross beta, Sr-89, Sr-90 and Cesion radioactivitu for silt samples. GeLi (: ganna spectrum 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 naturalls-occurring radioactivits, as discussed above for soil samples, in addition to ans other activits introduced into the aquatic environment which would settle onto or be absorbed by the silt. As can be PAGE 25

( __ l seen bs comparison of the data in Tables IV.5.1 and IV.6.1, the activits levels in silt generalls are similar to those found in soil, exept as noted below. The concentrations of gross alpha radioactivitu at all sampling stations was general 19 a few tenths to 7 pCi/9 drs weight and are well within the range of variabilitu observed in PBAPS Units 2 and 3 preoperational period. Gross beta radioactivits concentration was generalls a few PCi/g dru weight. The results and variations between stations are consistent with the PBAPS Units 2 and 3 preoperational period. Sr-90 concentrations occurred within the approxinate range of 0.01 to 0.08 pCi/9 continuing the lower trend seen since 1981. All results are within the range of variabilits observed during the PBAPS Units 2 and 3 preoperational period. Sr-89 was found in one of the samples at the detection limit. This is probablu due to counting statistics. Sanples analuzed showed Cesion generalls at low levels of a l few hundredths to a few tenths of a pCi/9 dru weight which is I well within the range of PBAP'S preoperational data. A concentration of 8.02 +/-.07 pCi/9 was found at Station 1BB on October 25, 1983 and is related to PBAPS operation. Ans apparent discrepancu between the radio-chenistru values and ganna spectrum values nost probablu occurs because the ganna spectron 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 spectron analusis. Figures IV.6.1 and IV.6.2 compare Stations SD, 4J and 4T which are at increasing distances from the PBAPS discharge. There does not appear to be anu consistent correlation of the observed levels with particular locations when normal variabilits is taken into account. The preoperational data show approximatels the same spread in values and values of similar l Magnitude to those seen during this period. The observance of 3 Cs-134 at several of the locations is discussed below. Station

108, 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 IV.6.3 indicates no positive addition of Sr-90 radioactivits b3 PDAPS operation.

The concentrations of radioactive Cesium as shown in Figure IV. 6.4 indicate higher levels at Station 1BB, consistent with the ganna spectrum data. v PAGE 26 e

r 't Ganna spectron alaissis showed primarilu the presence of K-40 and the U, Th series as represented h3 Ra-226 and Th-220 {- respective 19, all of which are naturalls-occurring, and Cs-137. Several nuclides associated with PDAPS operation were found during 1903. Cs-134 was found in samples fron Stations 1BB, 1X, ( 4D, 4J and 4T. Co-60 and Zn-65 were found in samples from L Stations 1BB and 4J. Comparison of results between locations and with the f preoperational data indicates no addition of radioactivits due to the operation of PBAPS except for 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 PDAPS

releases, a

dose calculation using the USNRC Regulators Guide 1.109 model and assumptions results in a calculated dose [ of 6.94 E-3 mren to a teenager's skin. This calculation ( conservative 19 assunes that the teenager was exposed to the maxinun concentrations found for the entire expouare period. The calculated dose is 0.07% of 10CFR50 Appendix I design ( objectives. G. FISH ~ 1 The results of the analusis of fish samples for l concentrations of gross beta, M-40, net beta, Sr-89 and Sr-90 { radioactivits are given in Tables IV.7.1 and IV.7.2. Ganna spectrun data are presented in Table IV.7.3. Mean values are - presented in Tables IV.7.1, IV.7.2, IV.7.4, and IV.7.5. St-90 l concentrations are plotted in Figure IV.7.1. Net beta radioactivits generalls ranged fron <10 to 30 PCi/9 i ash with an average of about 20 PCi/s ash. A high value of 200 [ pCi/q ash was found in a fish sample from the plant water discharge s3 sten. The composite samples from this location also l had relativelu high concentrations of several ganna-enitting nuclides. With this exception the values were well within the range of PDAPS preoperational data. Radiostrontion analysis was resoned on a temporaru basis diiring the second half of 1979 and continued through 1903 because of the possibilits of release of Sr-89 and Sr-90 from a source upstrean fran the Peach Botton site. Sr-09 was measured at the detection linit in a few of the sanples at a few tenths of a PCi/9 ash. ( Sr-90 radioactivitu concentration as determined in samples fron all locations was generally several tenths to approxinatels y 2 pCi/s ash corresponding to several hundredths to 0.1 pCi/9 g I original sample. The higher value was found in a sanple fran a I renote location above Holtwood Dan. t Stations 1EE and 4J, as a ercup of stations which could be L affected bu PBAPS operation, and Station 6H which is above Holtwood Dan and therefore unaffected bu PBAPS, are compared in E k PAGE 27 / L-

Figure IV.7.1. There is essential 19 no difference in the range of concentrations for SP-90 radioactivity in fish from these locations. Ganna spectrun ana13ses are shown in Table IV.7.3. In addition to naturalls-occurring K-40, Ra-226 and Th-228, and Cs-137 from atmospheric nuclear weapons test fallout, Cs-134 and Zn-65 were found in nost samples from Conowingo Pond and the plant water discharge susten. These nuclides were found at l Stations

1EE, 1X, 4I and 4J. In addition, tin-54, Cr-51, and l

Co-60 were found in a few samples hoth from Conowingo Pond and the plant water discharge systen. Sanples from Station 1EE taken on Septenber 9, 1983 had significant19 increased concentrations of Cs-137, Cs-134, Zn-65, l g Co-60, and tin-54. A review of plant operations indicated that the activity was nost like13 the result of liquid radioactive i waste releases during periods of lower-than-normal plant discharge canal flows. E>:aninati on of data indicates essential 19 no difference other than normal variabilits between off-site stations for all y nuclides except Cs-137, Cs-134 and Zn-65. The na>:inun dose l calculated using the USNRC Regulators Guide 1.109 nodel and assumptions is 6.05 E-01 nren to a teenager's liver. The actual dose due to PBAPS operations is

less, since the naxinun l

concentrations of radionuclides was asssumed to exist all sear. I In

addition, vers small concentrations of Cr-51 and Co-60 were found in on13 one and two samples respectivels and no credit was taken for Cs-137 from sources other than PBAPS. The calculated dose is 6.1% of the 10CFR50 Appendix I design otuettives.

H. VEGETATION The concentrations of gross beta, net beta, K-40, Sr-89, Sr-90, and Cesion radioactivitu are given in Tables IV.O.1 and IV.G.2 for vegetation samples. tiean values are in Tables IV.O.1 and IV.8.2. Figures IV.O.1 and IV.8.2 show annual mean values for Sr-90 and Cesion radioactivitu concentrations. l The concentrations of net beta radioactivitu are similar for all stations and appear to have approxinatelu the same spread. tieasur able values ranged from 20 to 50 PCi/9 ash. All results are in the range measured during the PBAPS Units 2 and 3 preoperational period. Corresponding values were generallu several tenths of a pCi/g original sample. The raw weight to l ashed weight ratio varies narkedlu between samples as would be expected from the different water content of various tupes of vegetables and vegetation. tie a s ur a b l e S r '7 0 radioactivits concentrations had a range PAGE 28

Is h. from about 1 to approximatelu 31 pCi/g ash with the naJoritu of values between 1 and 20 PCi/9 ash. Wild vegetation tended to have higher values probablu due to greater accumulation of g fallout _ because of the -longer growing season. These L concentrations are well within the range of PBAPS preoperational data. : The - corresponding values in terns of PCi/9 original sample .showed -a similar range from a few hundredths to a few tenths of h. a pCi/g. The annual 'nean values of-site area and distant stations, as shown in Figure IV.8.1 are approximatelu the same. { 'Sr-89 was detected in several samples probablu due to counting statistics, since there is a relativelu large amount-of Sr-90 present. h Cesiun radioactivitu was generalls measured at concentrations from a few tenths to a few pCi/g ash. The highest value was seen at remote Station 3A. The corresponding average h' values were a several thousandths to a few hundredths of a pCi/9 -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 radioactivits in vegetation from the operation of PBAPS. h 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 Tabl es 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, farns have been divided into three groups: one containing Farns G, J, and 0, which ara ( regional farms near the Peach Botton site; a second consisting of Farms A, B, C and E, which encircle the Peach Botton site at renote 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 radioactivitu generalls ranges [ from undetectable to a few hundred PCi/l as has been the case during and since the preoperational period. The major beta activitu in nilk is due to the presence of naturallu-occurring h K-40 at concentrations of approximatelu 900 pCi/1. The residual net beta values are most probablu the result of the difference between two tupes of aeasurements and are not real. The gross (' beta radioactivits is neasured directlu on milk ash while the K value is calculated from chemical measurement of potassion on dissolved ash. From the known Metabolic process of cows, it is-unlikelu that anu radioactive nuclides from a nuclear power -plant other than those of strontium, cesion, barivn-lanthanun, PAGE 29 4 b.

? hsdrogen orfiodine would befpresentsin milk. The Sr-90 radioactivits concentration for~all farms was-in the range of_ about 3 to 9 pCi/1. This range is similar to the J l I tranges =for 1975 through '1982. These concentrations are well within-the range of PBAPS preoperational-data, i" . The: annual nean values of Sr-90 for each farn group as shown in Figure IV.9.1 generalls lie between 4 and 5 pCi/1. Comparison -of 'the-historical St-90 data'shows a statisticalls significant -difference' (P<.001)- between near,. intermediate,- and distant-1 . farms. Near and distant farms have the highest and lowest mean j .results .respectivels. This. trend was noted in~ both the PreoPerational and postoperational periods. The-preoperational/postoperational mean ~ ratios are similar and . ] therefore the higher Sr-90-radioactivits concentrations observed at the near-farms-are not due.to PBAPS operation. St-89 was found .in a four of the samples.at the detection limit, most likels due to counting statistics. Measurable values for-Cs-137. radioactivits concentration range from 2 to-10 PCi/1, similar to-the. range seen earlier. No significant difference was observed among the three farn groups H as can be seen fron. Figure IV.9.2. The results are similar to: those measured during Units 2 and 3 preoperational period. Cs-134 was detected in one sample, probablu due to counting statistics.The general absence of Cs-134 indicates that the Cs-137 is due to atmospheric nuclear. weapons testing. I-131 radioactivits concentration

results, corrected for-

- ] decas .to date of sampling, are presented in Table IV.9.1. I-131 was barels detected in a few of the samples analuzed, probablu ] due to counting statistics. None of.the sanples contained.radioactivits which can be attributed to the operation of PBAPS. J. RABDITS Tables IV. 10.1 and IV. 10.2 present the analytical data ~and-Mean values obtained from the anaissis for gross beta, K-40, and~ net -beta radioactivits concentrations in rabbit bone, soft 1

Samples collected Juls 4 through Juls 9 represent the first half of the seat. Measureable net beta radioactivits concentration in muscle and soft tissue ranged fron 30 to 70 pCi/9 ash indicating that ? s PAGE 30 Y [J _I
