I. Summary and Conclusions This report on the Radiological Environmental Monitoring Program (REMP) conducted at the Peach Bottom Atomic Power Station (PBAPS) by Philadelphia Electric Company (PECo) covers the period 1 January 1990 through 31 December 1990. This report combines the results of the programsconductedbyTeledyneIsotopes(TI)andCleanHarbors(CH)
Laboratories. During this period 2,166 analyses were performed on 1,942 samples.
Surface water and drinking (potable) water samples were analyzed for concentrations of gross beta, gamma spectrometry, and tritium, l
Additionally, drin(ing water samples were analyzed for concentrations of Iodine-131. Pesults of these analyses showed no significant diffe*ences between contr.sl 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 nedia were analyzed for concentrations of gamma emitters. No measurable (Jfacts from the operation of PBAPS were detected.
The atmospheric environment was divided into two parts for examination:
airborne and terrestrial. Sample media for determining airborne effects include air particulates und air iodine samples. Analyses performed on air particulate samples included gross beta and gamma spectrometry. The l 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 l observed. These firAings indicate no measurable effects from the operation of PBAPS.
High sensitivity lodine-131 analyses were performed on weekly air
, samples. All results were less than the minimum detectable level.
i Examination of the terrestrial environment was accomplished by analyzing milk samples for concentrations of Iodine 131 and gamma emitters.
Results fror, all analyses were consistent with those from previous years and no indi:ation 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. These results were consistent with those from previous years.
l The operation of the Station had no ceasurable effect on the environs surrounding Peach Bottom.

!!. Introduction Peach Bottom Atomic Power Station (PBAPS) is located along the Susquehanna River between Holtwood and Conowingo Dams in Peach Bottom Town ship, York County, Pennsylvania. The initial loading of fuel into
( Unit 1,a40MWe(net)hightemperature,gascooledreactor,beganon5 f February 1966, and initial criticality was achieved on 3 March 1966.
Shutdown of Peach Bottom Unit I for decommissioning was on 31 October i 1974. For the purposes of the monitoring program, the beginning of the
) operational seriod for Unit I was considered to be 5 february 1966. A 1
summary a previousofreport t1e Unipu. preoperational PBAPS Units 2monitoring and 3 are program was presented boiling water reactors in each with a power output of approximately 1050 MWe (net). The first fuel was loaded into Peach Bottom Jnit 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.
Criticalitywasachievedon7 August 1974,andfullpowerwas(,fgst 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 radionuc & - in the environs of PBAPS site and any fluctuations in rt.dioactivity levels which may occur.
- 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 ds:ta 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.
- 2. Concentrations of gamma emitters in surface and drinking water, air particulates, milk, sediment, and fish.
3
- 3. Concentrations of tritium in surface and drinking water.
l 4. Concentrations of Iodine 131 in drinking water, air, and milk.
i'
- 5. Amt /' gamma radiation levels at various site environs.

111. Program Description A. Sample Collection This section describes the basic collection methods used to obtain environmental samples. For a more detailed account, including equipment used, refer to Apaendix E Section 1: Synopsis of Procedures - Collection Met 1ods.
Aountic Envirom ent 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 additional surface water locations (13A and 138) were collected as grab samples. Control locations were ILL and 61.
{ Fish samples from two groups, catfish (bottom feeder) and smallmouth bass (predator) were collected semiannually at two locations: 4 (indicator) and 6 (control).
Sediment samples composed of recently deposited substrate were collected at three locations semiannually: 4D, 4T (indicators),
and 6F (esntrol).
Atmesoberic 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 fifteen locations (IB, lZ, 2, 3A, 4A, 5, 6E,12D,14,15,17,31,32,33A,and3B). Control locations were 4A, 6E, and 120. Air iodine samples were collected from five locations (IB, lZ, 2, 3A, and 120). 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 9pproximately 1 cubic foot per minute.
Milk samples were collected from six locations (A, D, G, J, N, and
- 0) monthly from December through March and biweekly during the grazing season (April through November). Additionally, samples from five locations (C, D, E, L, and M) were collected quarterly.
Locations A, B, C, and E were controls.
Ambient Gamma Radiation Direct radiation measurements were made using thermoluminescent
_ _ _ _ _ _ _ J
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 (18, 10, ID, IE, IF, IG, lH IJ, IL, lH INH, 2, and 40) near and within the site perimeter, representing fencepost doses (i.e., at loca'. ions 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, 68, 14, 15, 17, 22, 23, 26, 27, 31, 32, 33A, 38, 42, 43, 44, 45, 46, l 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 (IA and II), designated as plant complex locations, are not inc uded in any of tie 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);
- 4. Near the dwelling closest to the main stack in the prevailing down wind direction.
A TLD set was placed at each location in a locked .armica
" birdhouse" or polyethylene jar located ap)roximately six feet above ground level. The TLD sets were excianged monthly and quarterly, then sent to the laboratory for analysis.
B. Data Interpretation Several factors are important for interpretation of the data presented in this report. These factors are discussed here to avoid unnecessary repetiti r in the discussion of the results.
The minimum detectabic level (MDL) was defined as the two sigma
t
[ counting statistic. It represents the range of values into which !
l 95% of repeated counts of the same aliquot would fall. For all ;
analyses an activity that was greater than or equal to the MDL was '
reported as " activity plus/minus the MDL value". When an activity was less than the MDL, the result was reported as the NMDL value". Data received from the laboratories were reported using the convention of rounding the result to the same number of significant places as the first significant digit in the error .
term (e.g., 3.62 1 1.24 rounds to 4 i It 10.93 2 0.96 rounds to -
10.9i1.0).
Results for each type of sample were grouped according to the analyses performed. Means'and stantard deviations of these results were calculated. These stardard deviations represent the ,
variability of measured results for iifferent samples rather than '
single analysis uncertainty. For thase calculations, all results below the MDL were considered to be at the MDL. As a result, the means were biased high, and the standard deviations were generally biased low.
C. Program Exceptions t for 1990 the P8APS REMP had a sample collection recovery rat: Of approximately 98%. The exceptions to this program are listed below:
- 1. Surface water sampler at location IMM was out of service from 01/16 to 01/18, 05/11 to 05/18, and 06/02 to 08/05 due to pump malfunctions. Grab samples were taken. ~
~
/ 2. Surface water sampler at location ILL was uut of service from i j 01/6 to'01/12, 07/06 to 08/22 due to pump malfunctions and from 12/19 to 12/21 due to low Pond elevation.- Grab samples were taken.
- 3. Surface water collections for location 138 were not performed for March and June since no water usage was recorded.
- 4. Drinking water sampicr at location 4L was- out of service from 06/02 to 06/10 and 11/09 to 11/24 due to pump malfunction.
Grab samples were taken.
- 5. Drinking water sampler at location 61 was out of service from 01/20 to 01/27, 07/01 to 07/07, 07/28 to 08/05, 08/18 to 08/25, 09/02 to 09/22, 10/06 to 10/12 10/21-to-12/02, and 12/16 to 01/04 due-to pump malfunctions. Grab samples were taken.
- 6. Air particulate sam)les were not available from the locations 15 and 120 during tie weeks of 10/06 to 10/12 and 10/09 to 10/15, respectively due a sample collection error.

- 7. Air particulate and air iodine samples were not available from location 2 during the week of 05/20 to 05/26 due to cat of-service equipment.
- 8. As a result of a typographical error our consultant responsible for collecting sediment samples did not collect at the required location 4J (Berkin's Run). Sediment samples were collected at location 4D (near the discharge outfall).
As a result the required ODCM sediment samples were not collected. The impact of this error was minimal because location 40 typically shows higher activity levels than location 4J. Consequently, any skin dose projection made using data from 40 would be more conservative. All vendors have been reinstra 'ed to cross check the information that they receive from PECo with that information that they may receive from other sources.
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 equi) ment breakdowns and power outages were unavoidable. T1e overall sample recovery rate indicates that the appro)riate procedures and equipment are in place to assure reliaale program impicmentation.
D. Program Changes The following are the changes for the 1990 PBAPS REMP:
- 1. Teledyne Isotopes (TI) became the primary laboratory for all REMP analyses. Clean Harbors (CH) became the QC laboratory for air particulates, surface water and milk.
- 2. Air particulate location 31 was discontinued.
- 3. TLD location 31 was dropped and replaced by another station 31A located within the same sector.
- 4. Game, vegetation, soil and well water sampling was discontinued.
- 5. Compositing of air particulate samples for gamma analysis was changed from monthly at seventeen ocations to quarterly at five locations.
- 6. Iodine-131 analysis of air iodine simples was conducted weekly at five locations instead of the previous year's eight.
- 7. Gross Alpha analyses were dropped from surface and drinking water samples.

IV. Results and Discussion A. Aquatic Environment
- 1. Surface Water Samples were collected from four locations monthly (ILL, IMM, 13A and 138). 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 soluble and insoluble fractions (Table .
C-I.1 and C-I.2 and Figures C-1 and C-2). The results for the soluble fraction ranged from 1.4 to 4.3 pCi/1. The mean for the *.hree indicator locations was 2.7 pCi/1, compared to the mean value of 2.4 pCi/l from the control location. The f results from analysis of the insoluble portion of all samples from the surface water locations ranged from <.4 to 4.5 pCi/1.
The mean of the indicator and control locations were 1.2 pCi/l and 1.8 pCi/1, respectively.
Tritium Samples from three locations (ILL, IMM, 13A) were analyzed for concentrations of aqueous tritium (Table C-1.3). Results ranged from <50 to 180 pCi/l and were within the range found during the preoperational period. Means from indicator and control locations compared well, with values of 100 pCi/l and 90 pCi/1, respectively.
Gamma Spectrometry Samples from all locations were analyted for concentrations of gamma emitters (Table C-1.4). The nuclides searched for were below the minimum detectable level with the exception of naturally occurring K-40. Potassium-40 was found at all locations and ranged from <4 to 30 pCi/1.
- 2. Drinkina (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 soluble and insoluble fractions (Tables C-II.1 and C-II.2 and Figures C-3 and C-4). Positive beta activity was detected in all soluble fraction samples from both locations ranging from 1.2 to 6 pCi/1. The values )
from the insoluble fraction ranged from <.4 to 8.0 pCi/1. I Only slight differences were observed between the means of the control and indicator stations. The values were generally below those seen in the preoperational period, lodine 131 Samples from both locations were analyzed monthly for 1-131 concentrations [ Table C-!!.3). Results from the indicator location were all less than MDL. One result (September) showed a positive activity of .15 pC1/1 at the control location.
Tritium Samples from both locations were analyzed for tritium concentration quarterly (Table C II.4). Results from both indicator and control locations indicate positive tritium activity, with no notable difference between the two locations. The indicator location values ranged from 70 to 200 pCi/l with a mean of 130 pCi/1. Control location values ranged from 80 to 110 pCi/1 with a mean of 100 pCi/1. The concentrations were within the range found during the preoperational period.
Gamma Soectrometry Samples from both locations were analyzed for concentrations of gamma emitters (Table C-II.5). The nuclides searched for were below the minimum detectable level, except for K-40 which was found in four samples at both locations and Ra-226 which was found in one sample. The values for K-40 ranged from <3 i
to 15 pCi/1. Ra-226 activity values ranged from <4 to 20 pCi/1.
- 3. Elih Samples were collected from two locations semi-arinually (4 and 6). The control location was 6. The following analyses were performed.
Gamma Spectrometry Positive activity was observed only for the nuclides K-40 which ranged from 0.7 to 3.3 pCi/g (wet). All other nuclides searched for were below the minimum detectable level (Table C-III.2). Figure C-5 illustrates the Cs-137 activity for indicator and control locations from the beginning of the operational period through the present. No Plant related nuclides were detected.
i 1
- 4. Sediment Samples were collected from three locations semi-annually (4D, 4T and 6F). The control location was 6F. The following analyses were performed.
Gamma Soectrometry Samples from all locations were anal gamma emitters (Table C IV.1). Berylfzed for found ium-7 was concentrations in two of of f six samples with values ranging from <.1 to .9 pC1/g (dry).
Potassium 40 was found in all samples ranging from 9.5 to 23 pCi/g (dry). Positive activity from Cs-137 was found at all locations with a mean value of .24 pCi/g (dry) for the indicator locations and .22 pCi/g (dry) for the control location. Radium 226 and Th 228 activity was found at all locations. 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 two indicator locations from the preoperational period through the present. No Plant related nuclides were detected.
B. Atmospheric Environment
- 1. Airborng
- a. Air Particulates Samples were collected from fifteen locations (IB, IZ, 2, 3A, 4A, 5, 6E, 12D, 14, 15, 17, 31, 02, 33A, 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 and C-V.2 and FiguresC-7andC-8). Air particulate locations are divided into three groups: Group I, consisting of IB, 1Z, and 2, located on site at PBAPS; Group II, comprised of 3A, 5, 14, 15, 17, 31, 32, 33A and 38, located at intermediate distances from PBAPS; and Group III, consisting of 4A, 6E and 12D, located at remote distance from PBAPS, Comparison of results among these three groups aids in determining the effects, if any, resulting from the operation of PBAPS.

, with afrom mean distant of IB E-3 )Ci/m3 . Comparison of the mean values indicate j no nota)1e difference among the three groups suggesting l
no effects from operation of PBAPS.
Gamma Spectrometry
, Samples from all locations were analyzed monthly 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. Airborne Iodine Continuous air samples weto collected weekly at five locations and analyzed for 1-131 (Table C-V1.1). All results were less than the minimum detectable level.
- 2. Terrestrial
- a. M Samples were collected from eleven locations (A, B, C, D, E, G, J L. H N, and 0). Farms A, B, C, and E were control locations. The following analyses were performed.
Iodine-131 Samples from all locations were analyzed for concentrations of I-131 (Tables C-VII.1). All results but one were less than the minimum detectable level.
Nearby Farm G had a positive result of .1 i .1 pCi/1 (04/23/90) which was at the detection limit.
Gamma Socctrometry Samples from five locations were analyzed quarterly for concentrations for gamma emitters (Table C-VII.2 and Figure C-9). Naturally occurring K-43 was found in all samples with values ranging from 1,200 to 1,500 pCi/1.
Positive concentrations of Cs-137 were detected at or slightly above the detection limit in about half of the amples. Values ranging from <2 to 7 pCi/1. Nearby Idrm J showed positive activity for Mn-54 and Ra-226 at the detection limit in February (.9 i .9 and 30 1 20 pCi/1,respectively). All other nuclides searched for were less than the minimum detectable level.
C. Ambient Gamma Radiation Ambient gamma radiation levels were measured at forty-seven locations (as described in the program description section) using CaSO 4 :Dy thermoluminescent dosimeters (Tables C-Vill.1 through C-Vill.4 and Figures C-10 and C-ll). Most monthly and quarterly TLD readings were below 10 mR/std. month with a range of 3.6 to 15.1 mR/std. month for the monthly's and 2.6 to 10.1 mR/std. month for the quarterly's. The high value of 15.1 occurred in April at control location 120. This exposure was suspect because of the high error (2 standard deviation) term associated with the result.
An investigation by the laboratory could give no explanation for this unusual result. The TLDs used at this location are not send at the same time as the TLDs for the other locations in the REMP.
No notable differences were observed among site-boundary, middle, and outer ring measurements. The data indicated that operation of PBAPS did not affect the existing ambient gamma radiation levels.

9 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) and the quality control laboratory, Clean Harbors (CH).
Comparison of the results for most media were within expected ranges, though occasional differences were seen:
Clean Harbors results of gross beta insoluble in surface and drinking water samples (Table D-I.2) were generally lower than the results from Teledyne Isotopes (Table C-I.2, Appendix C). The differences were probably due to differences in the laboratory's respective analytical procedures. CH ashes the sample prior to counting whereas TI does no ashing prior to counting.
CH had some difficulty meeting the MDL values required for La-140 in water samples.
Gross beta results for air particulate samples were similar for both laboratories (Figures D-1 and D-2).

APPENDIX E: SYNOPSIS OF ANALYTICAL PROCEDURES The following appendix is comprised of two sections: Section.1 describes the collection methods used to obtain samplas for the REMP, and Section 2 describes the methods and formulas used by Teledyne Isotopes and Clean Harbors to obtain the sample activities.

Section 1: Collection Methods Surface and Drinkina Water Samoles Surface and drinking water samples are composited over a one-month period at four locations (ILL, IMM, 4L, and 61). Water is continuously sampled at each location and collected in large tanks. Two quarts of water are removed from the tank each week and put into a clean two-gallon polyethylene bottle to form a -
monthly composite. At locations 13A and 138 a monthly grab sample is obtained.
Air Particulate and Air Iodine Samoles Air particulate samples are obtained using a rystem consisting of a pump, a glass fiber filter with a 35-mm diameter orifice, and a running time meter to indicate the total period of operation. At those locations where airborne iodine was also sampled, a charcoal filter was moentad behind the glass fiber filter. The volume sampled for the period if determined from the known flow rate and the running time. At the end of each weekly air particulate collection '
period, the air sampling unit is stopped. The filter is then removed from the holder and replaced with a clean filter, and the air sampling unit is returned .
to operation. (
Sediment Samoles Sediment samples are collected by one of 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 Grab with a surface area of 81 square inches. In shallow water (1-4 feet), sediment is collected by scooping up mud with a plastic two gallon bucket.
Milk Samoles Milk samples are obtained by removing two gallons from the dairyman's bulk tank, The sample from each location is therefore a composite of all the milk from the dairy herd (from 1 to 3 mil _ kings) . The milk is scooped from the agitated bulk {
tank and placed in new plastic containers.
Fish Samoles Fish samples are collected via several methods at Conowingo Pona locations; canal fish are caught by net trapping. Fish at other locations are caught by -
seine or electroshocking techniques.

Section 2: Analytical Methods and Calculations DETERMINATION OF GROSS BETA ACTIVITY IN WATER SAMPLES (TOTAL SUSPENDED AND DISSOLVED FRACTIONS)
Teledyne Isotooes 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.
The filter which represents the soluble portion of the sample is evaporated on a hotplate, and the residue is tranferred and dried on another planchet.
The planchets are counted for 50 minutes in alow-background gas flow proportional counter. Calculation of activity includes a self-absorption correction for counter efficiency based on. the . weight of residue on each I planchet.

< Teledyne Isotooes A 60 ml aliquot is distilled and collected in an Erlenmeyer flask. Approximately 4
55 g of the distillate is transferred into an electrolytic enrichment cell. One ml of 30% sodium hydroxide solution is added to the cell. The sample is
- electrolyzed in a 10 C cooling water bath until the volume is 3-4 mis. CO 2 is
! bubbled through the solution to neutralize the sodium hydroxide. The sample is i transferred to a collecting bottle at 80 C and weighed. -It is then transferred ,
into a liquid scintillation vial and 20 mis of cocktail- is added. The sample is
- counted for 100 minutes in a liquid scintillation counter.

DETERMINATION OF GROSS BETA ACTIVITY IN AIR PARTICULATE SAMPLES Teledyne Isotones 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 pariculate l filters because of the impracticality of accurately weighing the deposit and I because the penetration depth of the deposit into the filter is_ unknown. :

DETERMINATION OF I-131 IN MILK AND WATER SAMPLES 1
Teledyne Isotooes Two liters of sample are first equilibrated with stable iodide carrier. A batch treatment with anion excnange resin is used to. remove iodide f-w the sample.
The iodine is then stripped from the resin with sodium hypochlorw educed with hydroxylamine hydrochloride, and extracted into carbon tetrachiurie i as free iodine. It is then back-extracted as iodide into sodium bisulfite / lution and is precipitated as palladium iodide. The preci itate is weighed w chemical

DETERMINATION OF GAMMA EMITTING RADI0 ISOTOPES Teledyne Isotooes 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 Bureae of St ridards.

s Clean Harbors 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 all sample types; primarily air particulate filters, water, vegetation, soil, sediment, and fish.
A description of the analytical methods, beginr.ing with air particulates used for
{ each sample type is presented, followed by the general formula used for calculation of the sample activities.
Air particulate samples from each location at placed in a petri dish and counted on GeLi detectors connected to a multich...nel analyzer and micro computer.
Spectra are stored first on floppy disk, then on magnetic tape.
, Water and milk samples are placed into the appropriate sized container, depending on the volume of sample available. The preferred volume is 3.5 liters. The samples arc counted and spectra are stored as with air particulate samples.
) Vegetation samples are packed tightly in a tared container and weighed. Samples that contain excess liquid due to preservatives or decomposition are drained hefore weighing, and then returned to the container for counting. Samples such as grass are air drye<l to remove surface moisture before -eiv, 'ag and counting.
Samoles are counted and spectra stored as with air particulate samples.
I Soil samples are dried prior to weighing. An aliquot of dried >'mple is pla ed .
in a marinelli beaker and counted and spectra stored as with an particulate samples.
Fish samples from each location are placed into marinelli beakers fo counting.
The aliquot size may vary, depending on availability of sample, up ti 4 liters.
The samples are counted and spectra stored as for air particulate sa,ples.

ENVIRONMENTAL 00SIMETRY Teledyne isotooes Teledyne isotopes dosimeters are rectangular teflon wafers impregnated with 25%
CaSO4:0y phosphor. They are annealed in a hut 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 Isotopes model 8300 TLD reader. The dostmeter is tnen 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:
S Doso =
(R) ( g*#") (a vcon trol) where:
R - initial reading of the area RR - second reading of the area (after re-irradiation) redose - re-irradiation dose in mR avcontrni - average of control values calculated as explained below. If no controls are used, avcontrol O and gross exposures result B. Each area of each control is calculated by the formub:
cdose = (ct) ( credose y crr where:
cdose - control area dose in mR cr - initial reading of the control area crr -
second reading of the control area (after re-irradation) credose -
re-irradiation dose of the control dosimeter in mR E-15
The average of control values is then calculated from all four areas of all controls by the formula:
4W
[cdose avcontrol =
where:
N - total number of control dosimeters C. 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.

) 1991 The EPA section of the quarterly QC report is cumulative for the year. The table submitted with the last report of the year should be complete for results received and will be updated finally for results received later.
Results are presented as follows:

EPA Known 17 1.5,2.6,3)
EPA Gr. Avg. 16 yy,zz)
(xx) -
This value will be given when the precision (1 SD) of the CHAS measurement due to counting statistics is significantly different from the expected EPA precision. This should cause different spread in our results.
(1.0) -
Next to CHAS Avg. - This is the actual SD of the CHAS data (i.e., 1 SD, 1 determination). This means that an additional single measurement should yield a result within 1 SD of the mean 66% of the time.
(1.5,2.6,3) -
Next to EPA Known - The first number is the anticipated 1 SD as decreed by the EPA. This value can be compared to the figure above to see that the CHAS precision is as expected.
The second number is 3 SD of the mean which is the EPA Control Limit. If the observed mean (i.e. CHAS Avg.)
differs from the known by more than this value the result is unacceptable according to the EPA criteria.
The third number is the deviation from the EPA's known value.
(yy,zz) -
The first number is the observed 1 SD, 1 determination for all labs whose results were not deemed outliers. A significant difference between this value and the ene above it indicates that the anticipated precision is not being attained by the majority of the laboratories.
The second number is the normalized value for the grand average.
