1 This report on the Radiological Environmental Monitoring Program (REMP) conducted !
at the Peach Bottom Atomic Power Station (PBAPS) by Philadelphia Electric Company l (PECo) covers the period 1 January 1992 through 31 December 1992. This report !
combines the results of the programs conducted by Teledyne Isotopes (TI) and Public l
,_ Service Electric and Gas Company (PSE&G) laboratories. During this period 2,268 l analyses were performed on 1,991 samples. .
Surface watei and drinking (potable) water samples were analyzed for concentrations of gross beta, gamma spectrometry, and tritium. Additionally, drinking water samples were !
analyzed for concentrations of Iodine-131. Results of these analyses showed no j 4
significant differences between control locations and potentially-affected stations. The i values observed were within the ranges noted in the preoperational report. :
The remaining sample media representing the aquatic environment included fish and :
sediment samples. These media were analyzed for concentrations of gamma emitters. ,
Fish samples showed no measurable effects from the operation of PBAPS. Sediment '
Location 4J, located below the discharge, showed Co-60 slightly above the detection limit.
Cesium-137 was found at all locations. Results were consistent with data from previous i years. ,
The atmospheric environment was divided into two parts for examination: airborne and terrestrial. Sample media for determining airborne effects include air particulates and air [
iodine samples. Analyses performed on air particulate samples included gross beta and ,
gamma spectrometry. The results from both analyses were generally consistent with results from the previous years. Furthermore, no notable differences among results from '
on-site, intermediate, and distant locations in either analysis were observed. These findings indicate no measurable effects from the operation of PBAPS.
i High sensitivity Iodine-131 analyses were performed on weekly air samples. All results were less than the minimum detectable level. :
l Examination of the terrestrial environment was accomplished by analyzing milk samples ,
for concentrations of Iodine-131 and gamma emitters. Results from all analyses were i consistent with those from previous years and no indication of PBAPS effect. j Ambient gamma radiation levels were measured monthly and quarterly throughout the year. Most monthly and quarterly measurements were below 10 mR/std. month. These results were consistent with those from previous years. l The operation of the Station had no measurable effect on the environs sunounding Peach Bottom.

II. Introduction l Pea;5 Bottom Atomic Power Station (PBAPS) is located along the Susquehanna River between Holtwood and Conowingo Dams in Peach Bottom Township, York County, !
Pennsylvania. The initial loading of fuel into Unit 1, a 40 MWe (net) high temperature, .
- gas-cooled reactor, began on 5 February 1966, and initial criticality was achieved on 3 !
l March 1966. Shutdown of Peach Bottom Unit I for decommissioning was on 31 October (
1974. For the purposes of the monitoring program, the beginning of the operational i period for Unit I was considered to be 5 February 1966. A summary of the Unit 1
- preoperational monitoring program was prese:nted in a previous repon m. PBAPS Units 2 and 3 are boiling water reactors each with a power output of approximately 1050 MWe :
(net). The first fuel was loaded into Peach Bottom Unit 2 on 9 August 1973. Criticality l was achieved on 16 September 1973, and full power was reached on 16 June 1974. The i first fuel was loaded into Peach Bottom Unit 3 on 5 July 1974. Criticality was achieved :
on 7 August 1974, and full power was first reached on 21 December 1974. !
. Preoperational summary reports " for Units 2 and 3 have been previously issued and ;
i summarize the results of all analyses perfomied on samples collected from 5 February l 1966 through 8 August 1973.
A. Objectives The objectives of the REMP are:
l
- 1. To identify, measure, and evaluate existing radionuclides in the environs of ;
! PBAPS site and any flucinations in radioactivity levels which may occur.
l
- 2. To monitor and evaluate ambient radiation levels. f
- 3. To determine within the scope of the program, any measurable quantity of radioactivity introduced to the environment by the operation of PBAPS. i
! B. Implementation Implementation of the stated objectives is accomplished by identifying significant ;
l exposure pathways, establishing baseline radiological data of media within those l pathways, and monitoring those media during plant operation to assess plant effects ,
l (if any) on man and the environment. ,
In order to achieve the stated objectives, the current programs include the following !
l analyses on samples collected:

III. Program Description ,
A. Sample Collection !
This section describes the collection methods used to obtain environmental samples for the PB APS REMP in 1992. Samples for the PBAPS REMP were collected for PECo by RMC Environmental Services, Inc. (RMC).
Aquatic Environment The aquatic environment was examined by analyzing samples of surface water, drinking water, fish, and sediment. Surface water from two locations (ILL and IMM) and drinking water from two locations (4L and 61) were collected weekly from a tank at each location and were composited into a monthly sample for analysis. Two quarts of water are removed from the tank each week and placed into i
i clean two-gallon polyethylene bottle to form a monthly composite. Two additional surface water locations (13A and 13B) were collected as monthly grab samples.
Control locations were ILL and 6I. t Fish samples comprising the flesh from two groups, catfish (bottom feeder) and smallmouth bass, largemouth bass, or bass (predator) were collected semiannually '
at two locations: 4 (indicator) and 6 (control) using several methods such as trapnet, seine or electroshocking.
Sediment samples composed of recently deposited substrate were collected semiannually at three locations: 4J,4T (indicators), and 6F (control) using one of j two methods, determined by the depth from which the sediment is obtained. In ;
water greater than 4 feet deep, sediment is collected by either a Ponar or Ekman i Grab with a surface area of 81 square inches. In shallow water (1-4 feet), sediment [
was collected by scooping up mud with a plastic bucket.
Atmospheric Environment i i
- The atmospheric environment was examined by analyzing airborne and terrestrial samples. These consisted of air particulates, airborne iodine, and milk. Air :
particulate samples were collected and analyzed weekly from thirteen locations (IB, j lZ,2,3A,4A,5,6E,12D,14,15,17,32, and 38). Controllocations were 4A,6E, j and 12D. Air iodine samples were collected from five locations (IB, lZ,2,3A, and 12D). Control location was 12D. Air particulate and air iodine samples were obtained using a vacuum sampler, glass fiber and charcoal filters, respectively. The-filters were replaced weekly and sent to the laboratory for analysis. The vacuum samplers were run continuously at approximately I cubic foot per minute.
Milk samples were collected from five locations (A, G. J, N, and O) monthly from j I
. . - - - - _ - ~ .
1 December through March and biweeldy April through November. Additionally, )
samples from six locations (B, C, P, E, L, and P) were collected quarterly. !
Locations A, B, C, and E were controls. Milk samples were obtained by removing two gallons from the dairyman's bulk tank after mixing. The sample from each '
location is therefore a composite of all the milk collected from the dairy herd (from I to 3 milkings). The milk is scooped from the agitated bulk tank and placed in new l plastic containers.
Ambient Gamma Radiation Direct radiation measurements were made using thermoluminescent dosimeters ;
(TLDs) consisting of calcium sulfate (CaSO4 ) doped with dysprosium (Dy). Samples were collected from forty-seven locations. The TLD locations were placed on and i
around the PBAPS site using a "three ring concept":
A site boundary ring consisting of thirteen locations (IB, IC, ID, IE, IF, IG,1H, ,
IJ, IL, IM, INN, 2, and 40) near and within the site perimeter, representing fencepost doses (i.e., at locations where the doses will be greater than maximum annual off-site doses) from PBAPS releases; A middle ring consisting of twenty-five locations (3A,4K,5,6B,14,15,17,22,23, 26, 27, 31 A, 32, 33 A, 38, 42, 43, 44, 45, 46, 47, 48, 49, 50, and 51) extending to i j
approximately ten miles from the site, designed to measure possible exposures to close-in population; !
An outer ring consisting of seven locations (12D,16,18,19, 20, 21B, and 24) !
extending from approximately 10 to 60 miles from the site, and considered to be unaffected by station releases.
Two on-site locations (IA and II), designated as plant complex locations, are not l included in any of the three nngs.
The specific TLD locations were determined by the following criteria:
- 1. The presence of relatively dense population; Site meteorological data taking into account distance and elevation for each 2.
of the 36 ten-degree sectors around the site, where estimated annual dose from PBAPS,if any, would be more significant; ;
- 3. On hills free from local obstructions and within sight of the vents (where practical); l 5-
J r
l l
- 4. Near the dwelling closest to the main stack in the prevailing down wind l direction. i A TLD set was placed at each location in a locked formica " birdhouse" or '
polyethylene jar located approximately six feet above ground level. The TLD sets were exchanged monthly and quanerly, then sent to the laboratory for analysis. i B. Data Interpretation l Several factors are important for interpretation of the data presented in this repon. t These factors are discussed here to avoid unnecessary repetition in the discussion of l the results. ;
The minimum detectable level (MDL) for Teledyne Isotopes was defined as the 2 sigma counting statistic. The MDL for PSE&G was defined as the 1.96 sigma. Both def'mitions represent the range of values into which 95% of repeated counts of the l same aliquot would fall. All analyses were designed to achieve the required PBAPS detection capabilities for environmental sample analysis. For a more detailed description of the results calculation, see Appendix E. ;
For the analyses gross beta, tritium, and iodine-131 (when analyzed by beta ,
counting), the activity was reported plus/minus the counting statistic (MDL). This includes calculated negative activity. For the analyses gamma and iodine-131 (when .
analyzed by gamma spectroscopy), an activity that was greater than or equal to the !
MDL was reported as " activity plus/minus the two sigma counting statistic". When an activity was less than the MDL, the result was reported as "< the MDL value".
Data received from the laboratory were reponed using the convention of rounding :
the result to the same number of significant places as the first significant digit in the ;
error term (i.e.,3.62 i 1.23 rounds to 4 i 1; 10.93 i 0.96 rounds to 10.9 i 1.0; -0.01 l i 0.1 rounds to 0.0 i 0.1). Results for each type of sample were grouped according !
to the analyses performed. For gamma analyses, at least those nuclides required for ,
each sample media and nuclides which had a positive occurrence were reponed.
Means and standard deviations of these results were calculated. These standard deviations represent the variability of measured results for different samples rather than single analysis uncertainty. For these calculations, all results reported as <
MDL were considered to be at the MDL. ,
C. Program Exceptions P
For 1992 the PBAPS REMP had a sample collection recovery rate of approximately 99%. The exceptions to this program are listed below:
4
- 1. Air particulate samples were not available from location 5 from week #19 and
- 20 due to pump failure.
- 2. Air particulate samples for all locations except 12D from week #25 were lost l in shipping i t
The specific dates for the above weeks may be found in Table C-IX.1, Appendix C. {
l
- 3. Surface water sampler at location IMM was out of service from 01/02 to ;
05/28,08/03 to 08/13,08/23 to 09/28 and from 12/10 to 12/23 due to pump j malfunctions. Daily grab samples were taken. !
I
- 4. Surface water sampler at location ILL was out of service from 01/02 to 03/12 {
due to pump malfunctions. Daily grab samples were taken. l As a result of the composite water samplers being out of service for an extended length !
of time at locations ILL and IMM, a Technical Specification violation was issued by i the NRC. The Commission determined that the samplers should have been repaired and !
placed back in service in a more timely manner.
The following corrective actions were developed: ;
a) Review and revise the appropriate chemistry procedure for l compositing of monthly water samples. !
b) Review with Maintenance Planning the Tech. Spec. status of the [
composite water samplers and the appropriate actions to take to [
be in compliance with the Tech. Specs. ,
- 5. Surface water collections for location 13B was not performed for October f because no water usage was recorded. 'f i
- 6. Drinking water sampler at location 4L was out of service from 04/10 to 04/17 !
due to pump maintenance. Weekly grab samples were taken. .
r i
- 7. Drinking water sampler at location 6I was out of service from 04/04 to 04/10, l 08/07 to 08/14, and 08/21 to 08/28 due to pump malfunctions. Weekly grab i samples were taken. j
. 8. TLDs for location 12D were not available for May due to a laboratory j scheduling error. j
- 9. The MDLs for Ba-140 and La-140 for milk samples collected 11/09/92 for the I primary laboratory were not met because the required gamma analysis was not j
i assigned at sample receipt. I l
Each program exception was reviewed to understand the causes of the program :
exception. Sampling and maintenance errors were reviewed with the personnel involved to prevent a recurrence. Occasional equipment breakdowns and power outages were unavoidable. The overall sample recovery rate indicates that the appropriate l
procedures and equipment are in place to assure reliable program implementation. ,

A. Aquatic Environment
- 1. Surface Water t
Samples were collected from four locations monthly (ILL, IMM,13A and 13B).
ILL served as the control location. The following analyses were performed.
l Gross Beta .
}
Samples from all locations were analyzed for concentrations of gross beta in both insoluble and soluble fractions (Table C-1.1 and C-1.2 and Figures C-1 and C-2).
The results from analysis of the insoluble portion of all samples from the surface r water locations ranged from -0.2 to 4.2 pCi/1. The means of the indicator and j control locations were 1.1 pCi/1 and 0.7 pCi/1, respectively. The results for the .
1 soluble fraction ranged from 0.2 to 5 pCi/L The mean for the three indicator [
locations was 2.4 pCi/1, compared to the mean value of 2.3 pCi/1 from the control location.
Tritium I
!. Samples from three locations (1LL, IMM,13A) were analyzed for concentrations of tritium (Table C-1.3). Results ranged from -100 to 210 pCi/1 and were within
, the range found during the preoperational period. Mean activity values from ,
i indicator and control locations were 60 pCi/l and 90 pCi/1, respectively. j Gamma Spectrometry l .
Samples from all locations were analyzed for concentrations of gamma emitters ;
i (Table C-1.4). The nuclides searched for were below the minimum detectable level with the exception of the naturally occurring nuclides K-40,' Ra-226 and l' Th-228. Potassium-40 was found at alllocations except ILL and ranged from
<3 to 21 pCi/1. Radium-226 and Th-228 were each found in one sample from j Location ILL. j L
- 2. Drinkine Potable) Water f Samples were collected from two locations monthly (4L and 61). 61 served as the !
control location. The following analyses were performed. ,
Gross Beta
- Samples from both locations were analyzed for concentrations of gross beta i;
activity in insoluble and soluble fractions (Tables C-II.1 and C-II.2 and Figures I
. C-3 and C-4). Gross beta activity in the insoluble fraction ranged frem -0.1 to I
l.4 pCi/1. The values in the soluble fraction ranged from 0.3 to 3.7 pCi/I. No differences were observed between the means of the control and indicator -
stations. The values were generally below those seen in the preoperational period.
Iodine-131 l Samples from both locations were analyzed monthly for I-131 concentrations (Table C-II.3). The values ranged from -0.1 to 0.11 for the indicator location and from 0.0 to 0.34 for the control location. !
Tritium Samples from both locations were analyzed for tritium concentration quarterly l (Table C-II.4). The values for the indicator location ranged from 0 to 100 pCi/1 !
with a mean of 60 pCi/1. Control location values ranged from -100 to 100 pCi/1 l with a mean of 50 pCi/1. The concentrations were within the range found during l the preoperational period. l Gamma Spectrometrv !
Samples from both locations were analyzed for concentrations of gamma, emitters - (
f (Table C-II.5). The nuclides searched for were below the minimum detectable i level, except for K-40 which was found in 4 of 24 samples.
- 3. Fish ,
Samples were collected from two locations semi-annually (4 and 6). The control ;
location was 6. The following analyses were performed. .j Gamma Spectrometry i l
Positive activity was observed only for the nuclide K-40 which ranged from 1.9 l to 4.5 pCi/g (wet). All other nuclides searched for were below the minimum )
, detectable level (Table C-III.1). No Plant related nuclides were detected. Figure ;
C-5 illustrates the Cs-137 activity for indicator and control locations from the beginning of the operational period through the present.

.l Samples were collected from three locations semi-annually (4J,4T and 6F). The j control location was 6F. The following analyses were performed.
i l
i Gamma Spectrometry Samples from all locations were analyzed for concentrations of gamma emitters I f
(Table C-IV.1). Potassium-40 was found in all samples ranging from 7.4 to 23 ;
pCi/g (dry). The Plant related nuclide Co-60 was found in both samples from !
j Location 4J, which is downstream of the discharge . The mean result was 0.06 l l
pCi/ gram (dry) which was slightly above the detection limit. Positive activity from Cs-137 was found at alllocations with a mean value of.18 pCi/g (dry) for ,
the indicator locations and .10 pCi/g (dry) for the control location. Radium-226 l and Th-228 activity was found at all locations. The results were consistent with l those from previous years. Figure C-6 illustrates the comparison of activities of !
Cs-137 detected at the control location and indicator locations from the !
- preoperational period through the present.

- a. Air Paniculates (
l Samples were collected from thirteen locations (IB, lZ, 2, 3A, 4A, 5, 6E, j 12D,14,15,17,32, and 38). Controllocations were 4A,6E, and 12D. The !
- following analyses were performed.
i Gross Beta t t
Samples from all locations were analyzed for concentrations of gross beta (Tables C-V.1 and C-V.2 and Figures C-7 and C-8). Air particulate locations i l were divided into three groups: Group 1, consisting of IB, lZ, and 2, located >
on site at PBAPS; Group II, comprised of 3A,5,14,15,17,32,33A and 38, !
l j located at intermediate distances from PBAPS; and Group III, consisting of [
i 4A,6E and 12D, located at remote distance from PBAPS. Comparison of -
results among these three groups aids in determining the effects, if any, l resulting from the operation of PBAPS. The results from site location samples i ranged from 2 to 31 E-3 pCi/m', with a mean of 15 E-3 pCi/m'. The results [
from intermediate locations ranged from -1 to 35 E-3 pCi/m', with a mean of l
- 15 E-3 pCi/m'. The results from distant locations ranged from 0 to 33 E-3 l
- pCi/m', with a mean of 16 E-3 pCi/m'. Comparison of the values indicate no i notable difference among the three groups suggesting no effects from j operation of PBAPS (Figure C-7).

The following section contains data and figures illustrating the analyses performed by the l quality controllaboratory. Duplicate samples were obtained from several locations and media j and split between the primary laboratory, Teledyne Isotopes (TI) and the quality control l laboratory, Public Servic Electric & Gas (PSE&G). Comparison of the results for most media were within expected ranges, though occasional differences were seen: l t
PSE&G's results of gross beta insoluble and soluble in surface and drinking water samples (Table D-1.2) were generally lower than the results from Teledyne Isotopes (Tables C-I.1, C- j i
1.2, C-II.1 and C-II.2, Appendix C). The differences were probably due to contrasts in the j
respective laboratory's analytical procedures. PSE&G ashes the sample prior to counting whereas, TI does not.
PSE&G's gross beta results for air particulate samples were higher than TI's results, but the ;
trends were similar for both laboratories (Figures D-1 and D-2). PSE&G used Sr-90 as a j calibration source whereas, TI used Cs-137. .

APPENDIX E: SYNOPSIS OF ANALYTICAL PROCEDURES The following section contains a description of the analytical laboratory procedures along with an explanation of the analytical calculation methods used h' Teledyne Isotopes and Public Service Electric & Gas to obtain the sample activities.

DETERMINATION OF GROSS BETA ACTIVITY IN WATER SAMPLES (TOTAL SUSPENDED AND DISSOLVED FRACTIONS)
Teledyne Isotopes This describes the process used to measure the radioactivity of water samples without identifying the radioactive species present. No chemical separation techniques are involved.
For surface and drinking water samples, one liter of the sample is filtered under vacuum through a 0.45 micron Millipore filter. This filter represents the insoluble portion of the sample. The filter is dried and mounted on a planchet. He filter which represents the soluble portion of the sample is evaporated on a hot plate, and the residue is :ransferred and -
dried on another planchet.
The planchets are counted for 50 minutes in a low-background gas flow proponional counter.
Calculation of activity includes a self-absorption correction for counter efficiency based on the weight of residue on each planchet.

DETERMINATION OF GROSS BETA ACTIVITY IN WATER SAMPLES (TOTAL SUSPENDED AND DISSOLVED FRACTIONS)
Public Service Electric & Gas l i
This describes the process used to measure the overall radioactivity of water samples without identifying the radioactive species present. No chemical separation techniques are involved. l The sample is mixed thoroughly. Then, a 1.0 liter portion is removed from the surface or drinking water container and filtered through a slow, hardened ashless filter paper mounted in :
a Buchner funnel. The filter paper is removed from the Buchner funnel, folded into a l triangle, placed in a covered porcelain crucible and heated over a Bunsen bumer until completely charred. The crucible is then ashed for at least 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> in a muffle furnace at 500* C. The cooled ash is then transferred to a tared stainless steel ribbed planchet using a ;
rubber policeman with laboratory aerosol and reagent water.
The filtrate portion of the sample is evaporated on a hot plate until the volume approaches 20 i
to 25 ml. At that point, the filtrate is transferred to a tared stainless steel ribbed planchet.
Both planchets are evaporated to dryness under an infrared heat lamp. They are subsequently i cooled in a desiccator, weighed and counted using a low background gas proponional counter.

distillate is transfened into an electrolytic enrichment cell. One ml of 30% sodium hydroxide l
- solution is added to the cell. The sample is electrolyzed in a 10* C cooling water bath until !
the volume is 3-4 ml. CO is 2 bubbled through the solution to neutralize the sodium ;
hydroxide. The sample is transfened to a collecting bottle at 80" C and weighed. It is then ;
transfened into a liquid scintillation vial and 20 ml of cocktail is added. The san jle is !
counted for 100 minutes in a liquid scintillation counter. ,

, scintillation material and counted for a minimum of 100 minutes to determine its activity. I The tritium activity is determined by measuring the count rate in the beta activity energy '
I spectrum from 0 to 18 kev. Eighteen to 100 kev represents the carbon-14 energy region.
If there is no count rate above background in the carbon-14 energy region, the sample has no ;
- contamination and the tritium activity may be calculated directly. If the net count rate in the ;
carbon-14 energy channel is 10% of the tritium count rate or higher, the sample contains contamination that may affect the count rate in the tritium channel, and the sample must be ;
purified by distillation before recoundng. ,

DETERMINATION OF GROSS BETA ACTIVITY IN AIR PARTICULATE SAMPLES Teledvne Isotopes This describes the process used to measure the overall beta activity of air particulate filters without identifying the radioactive species present. No chemical separation techniques are involved. Each air particulate filter is placed directly on a 2-inch stainless steel planchet.
The planchets are then counted for beta activity in a low-background gas flow proportional counter. Calculation of activity includes an empirical self-absorption correction curve which allows for the change in effective counting efficiency caused by the residue mass.
Self-absorption is not considered in the case of air paniculate filters because of the impracticality of accurately weighing the deposit and because the penetration depth of the ~
deposit into the filter is unknown.

DETERMINATION OF GAMMA EMITTING RADIOISOTOPES Teledyne isotopes Gamma emitting radioisotopes are detemuned with the use of a lithium drifted germanium (GeLi) and high purity germanium detectors with high resolution spectrometry in specific media; such as, air particulate filters, charcoal filters, milk and water. Each sample to be assayed is prepared and counted in standard geometries such as one liter wrap-around Marinelli containers,300 ml or 150 ml bottles, or 2-inch filter paper source geometries.
Samples are counted on large (>55 cc volume) GeLi detectors connected to Nuclear Data 6620 data acquisition and computation systems. All resultant spectra are stored on magnetic -
tape.
The analysis of each sample consists of calculating the specific activities of all detected radionuclides or the detection limits from a standard list of nuclides. The GeLi systems are calibrated for each standard geometry using certified radionuclide standards traceable to t h a.

The procedure for detection of gamma emitting radioisotopes generates high resolution gamma spectra which are used for quantitative determination and identification. Standard -!
geometries have been established to maximize efficiency, for sample types: air particulate ;
filters, water, and milk.
A description of the analytical methods, beginning with air particulates used for each sample type is presented, followed by the general formula used for calculation of the sample- l activities.
Air particulate: At the end of each calendar quarter,13 weekly air filters from a given ['
location are stacked in a two inch diameter Petri dish in chronological order, with the oldest filter at the bottom, nearest the detector, and the newest one on top. The Petri dish is closed ,
and the sample counted.
Water and Milk: A well-mixed 3.5-liter sample is poured into a calibrated Marinelli beaker.
The samples are brought to ambient temperature and counted.

which contain copper shielding to filter out low energy radiation. After exposure in the :

four areas are read again. Calculation of the environmental exposure is performed by -
computer, using the re-irradiation readings to determine the sensitivity of each area of the !
- dosimeter. The reading of control dosimeters are subtracted to allow for transit dose and l system background. !

APPENDIX F: QUALITY CONTROL PROGRAM Teledyne Isotopes (TI) and Public Service Electric & Gas (PSE&G) panicipate in the EPA Radiological Inter-laboratory Comparison (cross check) Program. This participation includes a number of analyses on various sample media as faund in the Peach Bottom Atomic Power Station REMP. As a result of this panicipation, an objective measurement of analytical precision and accuracy as well as, a bias estimation of the results are obtained.
Examination of the data shows that the vast majority were within the EPA control limits.
Each case of exceeding the control limits was investigated. There was no evidence to suggest systematic errors.
The results of TI's and PSE&G's participation in the EPA cross check program can be found in Tables F-1 and F-2, respectively.
As part of another intercomparison program, thennoluminescent dosimeters (TLDs) from the NRC, Pennsylvania Department of Environmental Resources and PECo were placed at various distances around the Peach Bottom Atomic Power Station. The data were summarized into three categories: 0-2 miles,2-5 miles and greater than 5 miles from the Peach Bottom Atomic Power Station (Figures F-1 through F-3, Appendix F). The data overlap each other, indicating that each TLD system accurately represents the ambient gamma radiadon levels in the environs around the Peach Bottom Atomic Power Station.

Units are pC1/1 for water and milk except K is in ag/1.
(b) Teledyne Results - Average a 3 sigma. Units are pC1/1 for water and milk except K is in mg/1. Units are total pCi for air particulate filters.
l (c) There was large fraction of low energy beta emitters (Co-60 and Cs-134) in the sample. Detector efficiency decreases with l
decreasing energy. We are required to calibrate with the high energy beta emitters (Cs-137 and Sr-90). No corrective action necessary.
(d) There is no apparent reason for the high Cs-137 results. The sample geometry and detector efficiencies were verified to be correct. The Total K and I-131 by garuna spectroscopy were in good agreement with EPA values. There is no trend and results were within
- sigma so no action taken.
