- 1. Summary and Conclusions This report on the Radiological Environmental Monitoring Program (REMP) conducted at the Peach Bottom Atomic Power Station (PB APS) by PECO Energy covers the period 1 January 1994 through 31 December 1994. This report combines the results of the programs conducted by Teledyne Brown Engineering (TB) and Public Service Electric and Gas Company (PSE&G) laboratories. During this period 2,258 analyses were performed on 1,915 samples.
Surface water 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 significant differences between control locations and potentially-affected stations. The 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 Mn-54 and Co-60 activity which was attributable to PB APS operations. Cesium-137 activity was found at all locations and was consistent with data from previous years. The calculated dose to a teenager's skin from the sediment pathway was 1.73 E-03 mrem /yr which represents 0.01% of the allowable fraction of 10 CFR 50, Appendix I limits. The atmospheric environment was divided into two parts for examination: airborne and tenestrial. Sample media for determining airborne effects included air particulates and air iodine samples. Analyses performed on air particulate samples included gross beta and gamma spectrometry. The results from both analyses were 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 fm' dings indicate no measurable effects from the operation of PBAPS. liigh sensitivity lodine-131 analyses were performed on weekly air samples. All results were less than the minimum detectable activity. Examination of the terrestrial environment was accomplished by analyzing milk samples for concentrations of Iodine-131 and gamma emitters. Results from all analyses were consistent with those from previous years and showed no indication of PBAPS effect. Ambient gamma radiation levels were measured monthly and quarterly throughout the year. Most monthly and quarterly measurements were below 10 mR/std. month and consistent with those measured in previous years. The TLD results from location 50 for September were higher than historical values due radiography work being conducted on the nearby gas pipeline. The operation of the Station had no measurable effect on the environs surrounding Peach Bottom. Y~~ II. Introduction Peach Bottom Atomic Power Station (PBAPS) is located along the Susquehanna River i 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 March 1966. Shutdown of Peach Bottom Unit 1 for decommissioning was on 31 October 1974. For the purposes of the monitoring program, the beginning of the operational period for Unit I was considered to be 5 February 1966. A summary of the Unit 1 preoperational monitoring program was presented in a previous report S. PBAPS Units 2 and 3 are boiling water reactors each with a power. output of approximately 3458 MWt and 3293 MWt, respectively. The first fuel was loaded into Peach Bottom Unit 2 on 9 August 1973. Criticality was achieved on 16 September 1973, and full power was reached on'16 June 1974. The 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 summarize the results of all analyses performed on samples - collected from 5 February 1966 through 8 August 1973. A. Objectives ! The objectives of the REMP are:
- 1. To identify, measure, and evaluate existing radionuclides in the environs of PBAPS site and any fluctuations in radioactivity levels which may occur.
l
- 2. To monitor and evaluate ambient radiation levels.
- 3. To determine within the scope of the program, any measurable quantity of radioactivity introduced to the environment by the operation of PBAPS.
B. Implementation Implementation of the stated objectives is accomplished by identifying significant exposure pathways, establishing baseline radiological data of media within those pathways, and monitoring those media during plant operation to assess plant effects (if any) on man and the environment. In order to achieve the stated objectives, the current programs include the following analyses on samples collected:
- 1. Concentrations of beta emitters in surface and drinking water, and air particulates.

r 9 III. Program Description 1 A. Sample Collection l This section describes the collection methods used to obtain environmental samples for the PBAPS REMP in 1994. Samples for the PBAPS REMP were collected for PECO by Normandeau Associates, RMC Environmental Services Division. (RMC). Sample locations and descriptions can be found in Table B-1 and Figures B-1 through B-3, Appendix B. Aauatic 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 quacts of water are removed from the tank each week and placed into a 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 61. 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 two methods, determined by the depth from which the sediment was obtained. In water greater than 4 feet deep, sediment was collected by either a Ponar or Ekman 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 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, IZ,2,3A,4A,5,6E,12D,14,15,17,32, and 38). Control locations were 4A,6E, 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.
~
9 Milk samples were collected from five locations (A, G, J, N, and 0) monthly from December through March and biweekly April through November. Additionally, samples from six locations (B, C, D, 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 was therefore a composite of all the milk collected from the dairy herd (from 1 to 3 milkings). The milk was scooped from the agitated bulk tank and placed in new 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 around the PBAPS site using a "three ring concept": A site boundary ring consisting of thirteen locations (IB,1C,1D, 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, 33A, 38, 42, 43, 44, 45, 46, 47, 48, 49, 50, and 51) extending to 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 (I A and II), designated as plant complex locations, are not included in any of the three rings. The specific TLD locations were determined by the following criteria: !
- 1. The presence of relatively dense population;
- 2. Site meteorological data taking into account distance and elevation for each of the 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);
1 l
e , . 4 ( L '4. Near the dwelling closest to the main stack in the prevailing down wind ! direction. l 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 quarterly, then sent to the laboratory for analysis. t
' B. Data Interpretation Several factors are important in the interpretation of the data. These factors are ,
discussed here to avoid undue repetition in the discussion of the results. [
- l. Minimum Detectable Level The minimum detectable level (MDL) was defined as the smallest concentration of radioactive material in a sample that would yield a net count (above background) that would be detected with only a 5% probability of falsely concluding that a blank observation represents a "real" signal. The ,
MDL was intended as a before the fact estimate of a system (including ; instrumentation, procedure and sample type) and not as an after the fact , criteria for the presence of activity. All analyses were designed to achieve the required PB APS detection capabilities for environmental sample analysis.
- 2. Net Activity Calculation and Reportine of Results ,
Net activity for a sample was calculated by subtracting background activity from the sample activity. Since the REMP measures extremely small changes , in radioactivity in the environment, background variations will result in sample , activity being lower than the background activity effecting a negative number. For a more detailed description of the results calculation, see Appendix E. Teledyne Brown Engineering (TB) reported all analysis results except gamma spec results as Activity i 2 Sigma. Public Service Electric & Gas (PSE&G) reported all analysis results except gamma spec as Activity i 1.96 Sigma. TB reported all gamma spec results as Activity i 2 Sigma using two conventions (statistically significant and statistically non-significant activity). A Statistically Significant Activity was calculated activity that was greater than the individual sample's Minimum Detectable Activity and therefore most likely a "true positive result". A Statistically Non significant Activity was ' calculated activity that was below the. individual sample's Minimum Detectable Activity and therefore most likely not a "true positive result". Statistically Non-significant Activity includes calculated " negative activity". r
PSE&G reported gamma spec and iodine-131 analyses as Activity i 1.96 Sigrna counting statistic when the activity was greater than or equal to the 1.96 sigma. When an activity was less than the 1.96 sigma, the result was reported as "< the 1.96 sigma value". PSE&G refers to the 1.96 sigma value as the individual sample MDA. For specific equations please see Appendix E. Data reported in this report were generated 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 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 significant positive occurrence were reported. 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 < MDA were considered to be at the MDA. C. Program Exceptions For 1994 the PBAPS REMP had a sample collection recovery rate of approximately 99%. The exceptions to this program are listed below:
- 1. Air particulate sample from location 5 was not available for week 29 due to a pump mechanical problem.
- 2. Air paniculate sample from location 32 was not available for week 30 due to a pump mechanical problem.
- 3. Air particulate and air iodine samples from location IB were not available for week 2 due to an electrical problem and from weeks 29,30 and 33 due to a pump mechanical problem.
The specific dates for the above weeks may be found in Table C-IX.1, Appendix C.
- 4. Surface water sampler at location IMM was out of service for the following dates: 03/02 to 03/23,05/14 to 05/17,06/01 to 06/29 and 08/24 to 08/25 due to pump malfunctions or electrical problems. Daily grab samples were taken.
- 5. Surface water sampler at location ILL was out of service for the following dates: 05/14 to 05/17 and 06/01 to 06/29 due to pump malfunctions or electrical problems. Daily grab samples were taken.
7-
r
- 6. Drinking water sampler at location 4L was out of service from 12/16 to 12/23 due to pump malfunction. A grab sample was taken.
- 7. Drinking water sampler at location 61 was out of service for the following dates: 01/14 to 01/22 and 03/11 to 03/18 due to pump malfunctions. Grab samples were taken.
- 8. The MDL for iodine-131 in milk was not met for a sample from location J from 07/04/94 because of a low chemical yield, 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 procedures and equipment are in place to assure reliable program implementation.
D. Program Changes The following are the changes for the 1994 PBAPS REMP:
- 1. RMC Environmental Services, Inc. was acquired by Normandeau Associates in August.
- 2. New composite water samplers were installed at the intake (ILL) and discharge (IMM) beginning with the July sampling.

9 IV. Results and Discussion A. Aquatic Environment
- 1. Surface Water ,
Samples were collected from four locations monthly (ILL, IMM,13A and 13B). ' ILL served as the control location. The following analyses were performed. Gross Beta Samples from all locations were analyzed for concentrations of gross beta in both insoluble and soluble fractions (Table C-I.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 ' water locations ranged from -0.2 to 20 pCi/1. The means of the indicator and control locations were 1.4 pCi/l and 0.7 pCi/1, respectively. The results for the soluble fraction ranged from 1.8 to 9 pCi/1. The mean for the three indicator locations was 3.4 pCi/1, compared to the mean value of 2.7 pCi/l from the control location. t Tritium Samples from three locations (ILL, IMM,13A) were analyzed for concentrations of tritium (Table C-1.3). Results ranged from -100 to 100 pCi/l and were within the range found during the preoperational period. Mean activity values from indicator and control locations were both 0 pCi/1, respectively. Gamma Spectrometry Samples from all locations were analyzed for concentrations of gamma emitters (Table C-1.4). Statistically significant activity for naturally occurring K-40 was found in 10 of 43 samples. Potassium-40 results ranged from -50 to 32 pCi/1. No statistically significant fission or activation products were found.
- 2. Drinkine (Potable) Water 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 activity in insoluble and soluble fractions (Tables C-II.1 and C-11.2 and Figures C-3 and C-4). Gross beta activity in the insoluble fraction ranged from -0.2 to
r 3.5 pCi/1.' The values in the soluble fraction ranged from 1.8 to 4 pCi/1. 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 Samples from both locations were analyzed monthly for I-131 concentrations (Table C-II.3). The values ranged from -0.08 to 0.1 for the indicator location and from -0.08 to 0.32 for the control location. Tritium Samples from both locations were analyzed for tritium concentration quarterly (Table C-II.4). The values for the indicator location ranged from 0 to 10 pCi/1 with a mean of 0 pCi/1, Control location values ranged from -30 to 60 pCi/1 with a mean of 30 pCi/1. The concentrations found were lower than the range found during the preoperational period. Gamma Sxctrometry Samples from both locations were analyzed for concentrations of gamma emitters (Table C-II.5). Statistically significant activity for naturally occurring K-40 was found in 5 of 24 samples. Potassium-40 results ranged from -35 to 50 pCi/1. No statistically significant fission or activation products were found.
- 3. Fish Samples were collected from two locations semi-annually (4 and 6). The control location was 6. The following analyses were performed.
Gamma Spectrometry Statistically significant activity was observed only for the nuclide K-40 which ranged from 2800 to 3400 pCi/kg (wet) (Table C-III.1). No statistically significant fission or activation products were found. Figure C-5 illustrates the Cs-137 activity for indicator and control locations from the beginning of the operational period through the present.
- 4. Sediment Samples were collected from three locations semi-annually (4J,4T and 6F). The control location was 6F. The following analyses were performed.
Gamma Spectrometry Samples from alllocations were analyzed for concentrations of gamma emitters [ (Table C-IV.1). Statistically significant activity for K-40, Ra-226 and Th-228 was found at all locations. K-40 results ranged from 12,000 to 17,000 pCi/kg (dry). Statistically significant activity for the Plant produced nuclides Mn-54 and Co-60 were found in one of the two samples from the indicator location 4J located downstream of the discharge. The Mn-54 results ranged from 10 to 30 pCi/kg (dry) for the indicator locations and 20 to 20 pCi/kg (dry) for the control location. The Co-60 results ranged from -10 to 80 pCi/kg (dry) for the indicator locations and -10 to 10 pCi/kg (dry) for the control location. Statistically significant activity from Cs-137 was found at alllocations with a mean value of 220 pCi/kg (dry) for the indicator locations and 160 pCi/kg (dry) for the control location. The calculated dose from this pathway to a teenager's skin was 1.73 E-03 mrem /yr. This value is based upon the assumption the maximum concentration Mn-54, Co-60 and Cs-137 at the downstream location were present the entire year. This dose represents 0.01% of the allowable fraction of 10 CFR 50, Appendix I limits. The results were consistent with 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. B. Atmospheric Environment
- 1. A_irborne
- a. Air Particulates Samples were collected from thirteen locations (IB,1Z, 2, 3A, 4A, 5, 6E, 12D,14,15,17, 32, and 38). Control locations were 4A, 6E, and 12D. The following analyses were performed.
Gross Beta Samples from all locations were analyzed for concentrations of gross beta (Tables C-V.1 nd C-V.2 and Figures C-7 and C-8). Air particulate locations were divided into three groups: Group I, consisting of IB, lZ, and 2, located on site at PBAPS: Group II, comprised of 3A,5,14,15,17,32,33A and 38, located at intennediate distances from PBAPS: and Group III, consisting of 4A,6E and 12D, located at remote distance from PBAPS. Comparison of r-T results among these three groups aids in determining the effects, if any. resulting from the operation of PBAPS. The results from site location samples ranged from 7 to 32 E-3 pCi/m', with a mean of 16 E-3 pCi/m'. The results from intermediate locations ranged from 5 to 44 E-3 pCi/m', with a mean of 18 E-3 pCi/m'. The results from distant locations ranged from 6 to 34 E-3 pCi/m', with a mean of 18 E-3 pCi/m'. Comparison of the values indicate no notable difference among the three groups suggesting no effects from .t operation of PBAPS (Figure C-7). Gamma Spectrometry Weekly samples from five locations (IB,1Z, 2, 3A, and 12D) were composited and analyzed quarterly for the presence of gamma emitters (Table C-V.3). Naturally occurring Be-7 was found in all samples with activity - values similar to those from the preoperational years. Potassium-40 was found in approximately half of the samples at or slightly above the detection limit. No Plant related nuclides were detected.
- b. Airbome lodine Continuous air samples were collected weekly at five locations (IB, lZ,2,3A, and 12D) and analyzed for I-131 (Table C-VI.1). No statistically significant 1-131 was found.
- 2. Terrestrial
- a. Milk Samples were collected from eleven locations (A, B, C, D, E, G, J, L, N,0 and P). Farms A, B, C, and E were controllocations. The following analyses were performed, lodine-131 l
Samples from all locations were analyzed for concentrations of I-131 (Tables l C-VII.1). The values ranged from -0.10 to 0.1 pCi/l and were at or below the i minimum detectable activity. Both indicator and control farms had an average 1-131 concentration of -0.01 pCi/1, respectively. Gamma Spectrometry Samples from five locations were analyzed quarterly for concentrations for gamma emitters (Table C-VII.2 and Figure C-9). Naturally occurring K-40 1
9-was found in all samples'with values ranging from 1,200 to 1,600 pCi/1. All other nuclides searched for were less than the minimum detectable activity. C. Ambient Gamma Radiation Ambient gamma radiation levels were measured ' at forty-seven locations (as e described in the program description section) using CaSOgDy thermoluminescent dosimeters (Tables C-VIII.1 through C-VIII.4 and Figures C-10 and C-11). Most TLD readings were below 10 mR/std. month with a range of 3.2 to 15.2 mR/std. month for the monthly's and 3.10 to 9.0 mR/std. month for the quarterly's. The TLD reading from location 50 for the month of September was 15.2 mR/std. month. An investigation indicated that the elevated reading was due to radiography work being conducted on a gas pipeline located nearby. No notable differences were observed among site boundary, middle, and outer ring measurements indicating that operation of PBAPS did not affect the existing ambient gamma radiation levels.

4 The following section contains data and figures illustrating the analyses performed by the quality control laboratory. Duplicate samples were obtained from several locations and media and split between the primary laboratory, Teledyne Isotopes (TI) arid the quality control laboratory, Public Service Electric & Gas (PSE&G). Comparison of the results for most media were within expected ranges, though occasional differences were seen: PSE&G's results of gross beta insoluble and soluble in surface and drinking water samples (Table D-I.2) were generally lower than the results from Teledyne Isotopes (Tables C-I.1, C-1.2, C-II.1 and C-II.2, Appendix C). The differences were probably due to contrasts in the 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 calibration source ubeas, TI used Cs 137. 1 l D-1 l

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. The filter - which represents the soluble portion of the sample is evaporated on a hot plate, and the residue is transferred and dried on another planchet. The planchets are counted for 50 minutes in a low background gas flow proportional counter.

~ This describes the process used to measure the overall radioactivity of water I
samples without identifying the radioactive species present. No chemical separation techniques are involved. 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 triangle, placed in a covered porcelain crucible and heated over a Bunsen burner until completely charred.' The crucible is then ashed for at least 2 hours 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 - i laboratory aerosol and reagent water. The filtrate portion of the sample is evaporated on a hot plate until the volume ' approaches 20 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 cooled in a desiccator, weighed and counted using a low background gas proportional counter.

i DETERMINATION OF TRITIUM IN WATER BY LIQUID SCINTILLATION COUNTING Toledvne Brown Enaineerina Ten (10) milliliters of sample is directly pipetted into a 25 ml vial and mixed with liquid scintillation material and counted for a minimum of 100 minutes to determine its activity. The tritium activity is determined by measuring the count rate in the beta activity energy spectrum from 0 to 18 kev. Eighteen to 100 kev represents the carbon-14 energy region. If there is no count rate above tackground in the carbon-14 energy region, the sample has no contamination and ce 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 samp!e must be purified by distillation before recounting.

- separation techniques are involved. Each air particulate filter is placed directly on a l 2 inch stainless steel planchet. The planchets are then counted for beta activity in l
a low-background gas flow proportional counter. Calculation of activity includes J 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 particulate filters because of the impracticality of ; accurately weighing the deposit and because the penetration depth of the deposit
' into the filter is unknown.

The iodine is then stripped from the resin with sodium hypochlorite, reduced with F ! hydroxylamine hydrochloride, and extracted into carbon tetrachloride as free iodine.

.? DETERMINATION OF GAMMA EMITTING RADIOlSOTOPES Teledvne Brown Enoineerina Gamma emitting radioisotopes are determined 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 the National Bureau of Standards. l l Gamma Soectroscoov Statistically Sionificant Activity and 2 Siama Error fatiquiation for the ND6620 and ND6700 Svstems: Activity , AREA

o DETERMINATION OF GAMMA EMITTING RADIOlSOTOPES Public Service Electric & Gas 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 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.

*. ENVIRONMENTAL DOSIMETRY Toledvne Brown Enaineerina Teledyne Brown Engineering dosimeters are rectangular teflon wafers impregnated with 25% CaSO4:Dy phosphor. They are annealed in a hot air oven prior to use and are inserted into black polyethylene pouches. The filled pouches are labelled and placed in rectangular holders which contain copper shielding to filter out low energy radiation. After exposure in the environment, four separate areas of the dosimeter are read in a Teledyne Brown Engineering model 8300 TLD reader. The dosimeter is then re-irradiated by a standardized Cs-137 source and 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 system background.
A. For any given area of the dosimeter, the dose mR is calculated by the formula:
#8 -
(avcontrol) Dose = (R)( RR ) where: R = lnitial reading of the area
= second reading of the area (after re-irradiation) l RR '
redose = re irradiation dose in mR avcontrol = average of control values calculated as explained below. If no controls are used, avcontrol = 0 and gross exposures result l 1 I B. Each area of each controlis calculated by the formula: cdose = (ct)( ###) crr 1 where: cdose = control area dose in mR cr = initial reading of the control area crr = second reading of the control area (after re-irradiation) credose = re-irradiation dose of the control dosimeter in mR E - 13

The average and standard deviation of the area readings for each dosimeter - are calculated by standard methods. D. Using the criteria that if one standard deviation is greater than 10% of the average of the four readings and that if the value of one area is outside the range of 3 standard deviations of the average of the other three areas, then that area will be eliminated and the results will be based on the remaining areas. l l E-14 l J

Program. This participation includes a number of analyses on various sample media as found in the Peach Bottom Atomic Power Station REMP. As a result of this participation, 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 controllimits was investigated. There was no evidence to suggest systematic errors.

l EPA Results - Expected laboratory precision (3 sigma). Units are pCi/l for water and milk except K is in mg/1. (a) l (b) Teledyne Results - Average 3 sigma. Units are pCi/l for water and milk except K is in mg/1. Units are total pCi for air particulate filters. (c) There appears to be variation in self-absorption matrix. The EPA confirms that the composition of their tap water from Lake Mead, varies seasonally which can cause variation in alpha, beta results. !!o corrective action required at this time since results are within i 3 sigma control limits. (d) A second aliquot was analyzed, paying particular attention to volume aliquoted. The result, 52 pCi/1, was in good agreement with the EPA. The three original results, each counted on a different detector, showed good precision. Future EPA cross-checks will be weighed and results followed to The measurement of Co-60 has not been a problem. check for a possible trend "out of control". (e) The average value of three analyses en the " Report of Analysis" was 133 pCi/ liter which is in good agreement with the EPA. Apparently, incorrect results were entered into the EPA computer. Future data will be printed from the computer screen to check entries. (f) The EPA has indicated that the Radiation Quality Assurance Program has been experiencing problems with the ruthenium-106 analysis. (g) The first aliquot, prepared according to EPA dilution instructions was counted on four detectors in the 1 liter The Marinelli geometry with Cs-134 results (based on the 796 kev peak) in pCi/l of 32.0, 25.1, 31.7, and 30.B. 31.7 result was not reported.

Thus none of : sample preparation (dilution, volume determination, maintaining correct pH, etc.), sample gecmetry, or detector efficiency seem to be the cause of the low results. th) There is no apparent reason for the low result, however the average value, 85 pCi/l is in good agreement to the grand average (86.46). No corrective action planned. (i) EPA results for gross beta in water were corrected for 20% crosstalk into the beta channel from the Th-230 alpha The spike. Recent measurements show that the crosstalk can be much higher (37% for gamma products counter #1). normalized deviation from the grand average was only 0.38. Future results will be corrected with specific crosstalk values determined by counting Th-230 standards. (j) The milk sample was counted four times. The reported Cs-137 values were based on one aliquot of I liter volume and an aliquot of 0.865 liter counted two times. It is suspected that the 0.865 liter volume was incorrectly determined. If 1 liter (the usual volume for counting milk samples) is used in the calculation, then the average of three results equals 63.6 pCi/l which gives a normalized deviation to the Known of 1.59. The fourth count (a 1
- liter aliquot) had a Cs-137 equal to 64.2 pCi/l which is in good agreement with the average of the other three.
l Teledyne will set up a log for recording aliquots used for EPA samples and record how the aliquot volume was determined. (k) The EPA requires that water samples be diluted before gamma analysis. That imposes a feature not appropriate for the handling cf envircnmental samples. As in the 06/10/94 water sample, it appears that the first aliquot may not have been accurately prepared. A second aliquot was prepared and counted three times with results in pCi/l and normalized deviation of: I Co-60 60.6 0.55 Zn-65 100.0 0.00 Cs-134 22.9 -0.38 Cs-137 l 58.5 3.29 Ba-133 69.8 -0.79 i Four of the five are now in good agreement with the EPA results. The Cs-137 is high, but within the control limits when compared to the grand average deviation of all laboratories of 2.89. The grand average was 51.9 pCi/1. For future samples of this type we will have two technicians each prepare an aliquot and compare the counting results to check for preparation technique differences. F-4 .' s I
