I I LIMERICK GENERAT!HG STATION Radiological Environmental Monitoring Program II. Intreduction The Limerick Generating Station (LGS), consisting of two 1055 MWe boiling water reactors owned and operated by Philadelphia Electric I Company (PEco), is located adjacent to the Schuylkill River in Montgomery County, Pennsylvania. Unit No. I went critical on 22 December 1984 and Unit Ho. 2 is under construction. The site is located in Piedmont I countryside, transversed by numerous valleys containing small tributaries which feed into the Schuylkill River. On t he east ern river bank elevation rises from approximately 110 to 300 feet mean sea level (MSL). On the western river bank elevation rises approximately 50 feet MSL to I the western site boundary. A Radiological Environmental Monitoring Program (REMP) for LG5 was initiated in 1971. Review of the 1971 through 1977 REMP data result ed in the modification of the program to comply with changes in the Environmental Report Operating License Stage (EROL)8'I and t he current revision of the Branch Technical Position Paper.t ti The preoperational I period f or most media covers the periods 1 January 1982 through 21 December 1984 and was summarized in a separate report.838 This report covers those analyses performed by Teledyne Isotopes (TI) on samples I collected during the period 1 January 1985 through 31 December 1985.

I A. Objectives The object ives of the Radiological Environmental Monitoring Program are: 1. To provide data on measurable levels of radiation and radioactive materials in the site environs. 2. To evaluate the relationship between quantitles of radioactive material released from the plant and resultant radiation doses to individuals from principal pathways of exposure. B. Implementation Implementation of the stated objectives is accomplished by identifying significant exposure pathways, establishing baseline radiological data of media within those pathways, and continuously monitoring those media bef ore and during Stat ion operat ion to assess Stat ion ef f ect s (if any) on man and t he env'ronment. In order to achieve the stated object Ives, t he current program includes the f ollowing analyses on samples collected: 1. Concentrations of tritium in surface water, drinking (potable) water, and well water. 2. Concentrations of beta emitters in surface water, drinking (potable) water, and air particulates. 3. Concentrations of gamma emitters in surface, drinking l (potable), and well water, air particulates, milk, vegetation, game, fish, and sediment. 4. Concentrations of I-131 in air and milk. 5. Ambient gamma radiation levels at various site environs. l I l I ~ I _g _

I I III. Program Description A. Sample Collection Samples f or the LG5 REMP were collected f or Philadelphia Electric Company by Canberra /RMC. This section describes I the collect ion methods used by Canberra /RMC to obtain environmental samples f or the LGS REMP in 1985. Aountie Environment The aquatic environment was examined by analyzing samples of surface water, drinking water, fish, and sediment. Two gallon water samples were collected monthly from continuous samplers located at five surface water locations (10F2, 15F5, 16B2, 2451, and 2452) and four drinking water locations (15F4, 15F7, 16C2, and 28F3). One additional drinking water location (13H2) was sampled I monthly by compositing weekly grab samples. Control locations were 10F2, 2451, 24S2, and 28F3. All containers used were new unused plastic bottles, which were rinsed at I least twice with source water prior to collection. Fish samples comprising the flesh of two groups, cat f ish/ bullhead (bot t om feeder) and sunfish (predator). were collected semi-annually at three locations: 16C5 and I 2051 (indicator) and 29CI (control). Sediment samples composed of recently deposited substrate were collected at three locations semi-annually: 1652 and 16C4, (indicator) and 33A2 (control). Atmosoberic Environment The atmosphoric environment was examined by analyzing samples of air particulate, airborne I iodine, milk, well water, food products and game. Air particulate and airborne lodine samples were collected weekly at seventeen locations (281, 6C1, 9C1, 1053, 1151, I 13C1, 13H4. 1451, 15DI, 1781, 20DI, 22G1, 2681, 29PI, 31D1, 3452, and 3581). Of the airborne lodine samples at these seventeen locations, eight (1053, 1151, 13C1, 13H4, 1451. 22G1, 31DI, and 3581) were analyzed for I-131. The I remaining nine samples were collected and retained for analysis if necessary. Control locations were 13H4 and 22Gl. Air particulate and airborne lodine samples were I obtained using a vacuum sampler, glass f iber and charcoal filters, respectively. The filters were replaced weekly and sent to the laboratory for analysis. The vacuum I samplers were run continuously at approximately 1 cubic foot per minute. Milk samples were collected bi-weekly at four locations I (5C1, 10B1, 22Fl, and 25B1) and monthly at eight locations (36E1, 9El, 9G1, 11D1, 11El, 17C2, 18C1, and 21B1) during April t hrough November, and monthly at all locations during December t hrough March. Locations 9G1 and 22F1 were I I

I controls. Changes in some sample statlens occured in November. A more detailed explanation can be found in Section III.D. Samples were collected in new unused two gallon plastic bottles f rom the bulk tank at each location, ref rigerat ed, and shipped prompt ly t o t he laboratory. Ho preservative was added. Well water samples were collected semi-annually from two locations 1151 (indicator) and 18A1 (control) in new unused two gallon plastic bottles. Vegetation samples composed of broad leafy vegetation and root crops were collected monthly from one location (1151) during the growing season (May through September). A game sample was collected annually from one location (2655) by hunting. Ambient Gemma Rediation Direct radiation measurements were made using t hermoluminescent dosimeters (TLD) consisting of calcium sulfate (CaSD4) doped with thulium (Tm). For the first three quarters and calcium sulfate (CaSD4) doped with dyprosium (Dy) during t he f ourth quarter. The TLD locations were placed on and around the LGS site using a l "three ring concept" consistint,of: 5 A site boundary ring consisting of sixteen locations (3651, g 351, 551, 751, 1053, 1151, 1451, 1652, 1851, 2151, 2352, g 2551, 2653, 2951, 3251 and 3452) near and within t he site perimeter representing fencepost doses (i.e., at locations where the doses will be potentially greater than maximum l annual off-site doses) from LGS releasess M A middle ring consisting of twenty seven locations (281, g 2E1, 4El, 6Cl, 7El, 9C1, 10Et, 10F3. 13Cl, 13Et, 15DI, g 16F1, 17B1, 19D1, 20D1, 20F1, 24DI, 25DI, 2681, 28D2, 2951, 29El, 31DI, 31D2, 34El, 35B1 and 35Fl) extending to approximately 5 miles from the site designed to measure l E possible exposures to close-in population; i l And an outer ring consisting of five locations (5Hl. 13H3, g 18G1, 22GI and 32G1) extending from approximately 12 to 30 g { miles f rom the site and considered to be unaf f ected by LGS releases. 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 f or each of the 16-22 1/2 degree sectors around t he s it e, where estimated annual dose from LGS, if any, would be most significant; I I

I 3. On hills f ree f rom local obstruct ions and within s i ght of t he vent s (where pract ical) I 4. And near the closest dwelling to the vents in the prevailing downwind direction. Two TLD sets - each comprised of f our thermoluminescent I pho spho r s sealed in plastic to maintain integrity were placed at each locat ion in a PVC conduit located approximately three f eet above ground level. The TLD sets I were exchanged monthly and quarterly and sent to the laboratory for analysis. B. Data Interpretation The radionnalytical and direct radiation data collected prior to LG5 becoming operational will be used as a baseline with I which this operat ional data will be compared. For the purpose of this report, LG5 was considered operational at initial criticality. Several factors are important in t he I interpretation of the data. These factors are discussed here to avoid undue repetition in the discussion of the results. The minimum detectable level (MDL) was defined as t he two sigma I counting statistic. It represents the range of values into which 95% of repeated counts of the same aliquot would fall. For all analyses (gross beta, I-131, H-3 and gamma) en activity I that was greater than or equal to the MDL was reported as "act ivity plus/minus t he two sigma counting statittic". When an activity was less than the MDL, the result was reported as < the MDL value. The lower limit of detection (LLD) was defined as the smallest concentration of radioactive material in a sample that would I yield a not count (above background) t hat would be det ect ed with only a 5% probability of f alsely concluding that a blank observation represents a "real" signal. The LLD was intended as a bef ore the fact estimate of a system (including lgg instrumentation, procedure and sample type) and not as an after the fact criteria f or t he presence of act ivity. All analyses ( were designed to achieve the required LG5 detect ion l capabilities for environmental sample analysis. For a more detailed description of the results calculation, see Appendix t l D. lI llI l I

I Data received from the laboratory were reported using the convent ion of rounding t he result to the same number of significant places as the first significant digit in t he error term (i.e. 3.62 1 1.23 round to 411). Results f or each type of sample were grouped according to the analyses performed. For gamma analyses, at least those nuclides specified in Technical Specification table 3.12.1-2 for each sample media and nuclides g which had a positive occurance are reported. Means and 3 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 t hese calculat ions, all result s below t he MDL were considered to be at the MDL. As a result, the means were biased high, and the standard deviat ions were generally biased l E low.

In addit ion to the program except ions listed above, the milk samples collected on 5/21/85 received the I-131 analyses but did l not receive gamma isotopic (GeLI) analyses. This was due to a W combined sample collection error (the sample collector used an obsolete collect ion sheet which did not indicat e t hat a gamma analysis was required on these samples) and a laboratory error (the laboratory did not ref er to the REMP requirement s to assign the proper analysis on the sample receipt form. They incorrectly used the inf ormat ion supplied on t he sample collect ion sheet ). T hese samples were discarded prior to this error being discovered. The corrective actions taken were

1) Combined sample collectlon/ receipt forms were prepared which have the required analyses f or each sample printed on them.

2) Teledyne Isotopes will new store all LG5 perishable REMP i

samples for 90 days (previously samples were stored for 6 I weeks) af ter the analysis is complete. This will permit g data processing procedures to verify that all required g l analyses were performed. l I I l I I l I

I I D. Program Changes 1. Milk collected from stations 22Fl. 5C1, 1081 and 2551 were analyzed for gamma emitting radioisotopes (GeLi) commencing with the biweekly samples collected on 04/21/85. 2. Station SC1 did not supply milk after the Hovember collect ion due to a discont inuation of the nilking operations. 3. Milk Station 17C2 was changed to the biweekly set.edule af ter the Hovember sampling. 4. Stat ion 7E2 was added to the monthly milk schedule in December. In addit ion to t he program changes listed above, t hu Panasonic UD-2005 Environmental Thermoluminescent Dosimeter (TLD) system was replaced by the Teledyne Isotopes TLD system on 10/03/85. This I change was based on a review which showed that the Toledyne Isotopes Environmental TLD system was both more accurate and more precise. I I I I I lI !I I I lI l l I

I IV. Results and Discussion A. Aquatic Environment 1. Surface Water Samples were taken from five locations on a monthly schedule. Samples were collected from a continuous sampler at all five locations (10F2, 15F5, 1652, 2451, and 2452). Of these I locations, two (15F5 and 16B2) could be affected by Station d i s c harge. The following analyses were performed. Gross Beta Samples from all locations were analyzad for concentrations of gross beta in the soluble and insoluble fractions (Tables C-I I and C-II, Appendix C). Detectable activity was observed in the soluble and insoluble f ract ion of t he surf ace water temples. The values were consistant with previous years (Figures C-1 and I C-2, Appendix C) and ranged from 2 to 10 pCl/l for the soluble fraction and from (.4 to 3.8 pCi/l for the insoluble fraction. No difference in activity levels was observed between indicator and control locat ions f or the soluble fraction. The insoluble I f ract ion of t he sample f rom t he downstream location, 15F5, did not show signif icant ly higher act ivity t han the cont rol locations. However, the January and February samples or the I same fraction of downstream sample location 16B2 showed a higher activity (2.1 and 3.8 pCi/1 respectively) than the control locations. This higher activity is attributable to the elevated sediment content of the samples. These act ivit ies are I st ill below the required sensit ivity for this analysis and t heref ore t hese act ivit ies are not considered signi f icant. Tritium Samples from locations 10F2, 16B2, and 2451 were analyzed for aqueous tritium activity (Table C-III, Appendix C). Positive I tritium activity was observed at each sample location and values ranged from <70 to 400 pCi/1. No difference was observed between indicator and control stat ions and the values f were consistent with previous years. Gamma Sooetrometrv l i l B Samples from all locations were analyzed for gamma emitting nuclides (Tuble C-IV, Appendix C). With the except ion of l g naturally occurring K-40, all nuclides searched for were below l g the minimum detectable level. l ll

2. Drinkina (Potable) Water Monthly samples were taken f rom five locations. A manually composited sample was collected from location 13H2. Semples from locations 15F4, 15F7, 16C2 and 28F3 were collected from a continuous water sampler. Four stations (13H2, 15F4, 15F7 and 16C2) could oe af f ected by Stat ion discharge. The following analyses were performed: Gross Beta I Samples from all stations were analyzed for concentrations of gross beta in t he soluble and insoluble f ract ions (Tables C-V l and C-VI. Appendix C). T he values ranged f rom 1 to 7 pCi/l for the soluble fraction and from <.4 to.9 pCi/l for the insoluble 3 fraction. No significant difference in activity levels was observed between indicator and control locations f or bot h t he soluble and insoluble fractions. In addition, concentrations detected in both fractions were consistent with those observed in previous years (Figures C-3 and C-4, Appendix C). Tritium Samples from locations 15F4, 15F7, 16C2 and 28F3 were analyzed for aqueous tritium activity (Table C-VII, Appendix C). Positive tritium activity was observed at each sample location. The measurements ranged from (60 to 300 pCl/1. Ho significant difference in tritium activity was observed between the control l E and indicator locations. Cemme Soectromotrv Samples from all locations were analyzed for gamma emitting nuclides (Table C-VIII, Appendix C). With the except ion of naturally occurring K-40, all nuclides searched for were below W the minimum detectable level. 3. Elib Fish samples comprised of cat fish / bullhead (bottom feeder) and redbreast /pumpkinseed (predator) were collected at three locations (16C5, 2051 and 29C1) semi-annually. The following analysis was performed: Gm-ma Soectrometrv The edible portion of fish samples from all three locations was analyzed for gamma emitting nuclides (Table C-IX, Appendix C). With the exception of naturally occurring K-40, all nuclides searched f or were below t he minimum detectable level. 14 - I

I 4 Sediment Aquat ic sediment samples were collected at three locat ions I (1682, 16C4 and 33A2) semi-annually. Of these locat ions, two (16B2 and 16C4) could be affected by Station discharge. The following analysis was performed: I Gamma Soectrometrv Sediment samples from all three locations were analyzed for I gamma emitting nuclides (Table C-X, Appendix C). Nuclides detected were Be-7, K-40, Cs-137, Ra-226, and Th-228. The nuclides Th-228, Ra-226, and Cs-137 commonly occur in sediment from daughter decay of natural uranium, or from world-wide I fallout. Concentrat ions of Bo-7 were the result of cosmic rey activity and K-40 is a naturally occuring nuclido. In addition, concentrat ions of t hese nuclidos were consistent wit h I those detected during the preoperat ional REMP. B. Atmospheric Environment 1. Airborne a. Air Particulates Continuous air particulate samples were collected from seventeen locations on a weekly basis. The seventeen locations are separated into three groups: Group I represents locat ions within the LGS site boundary (1053, 1151, 1451 and 3452), Croup II represents locations near the LGS site (281, 6Cl, 9C1, 13C1, 15DI, 1781, 20D1, 2681, I 2981, 31DI, 35BI), and Group III represents control locations at remote distances from LGS (13H4 end 22Gl). The following analyses were performed: Gross Beta Weekly samples were analyzed for concentrations of beta I emitters (Table C-XI, Appendix C). The samples collected from 1/22/85 to 1/28/85 for stations I 1781, 20DI, 26B1, 2951, and 3452 showed higher than expected activities of 0.067, 0.10, 0.15, 0.15, and 0.13 pCi/m3 respectively. These filters were analyzed for gamma emit t ing nuclides and the results showed measurable I-131 I levels. A subsequent invest igat ion resulted in the following informations a) Effluent monitor detector release data and results of radiochemical effluent analysis conf irmed t hat no detectable activity was released from the Station. I I

I b) The meterological data for the filters' exposure period showed no trends of air flow from the Station toward the five effected air particulate stations, c) A field survey and telephone survey indicated t hat there were no potential commercial industry sources of radiological contamination in the vicinity of the affected area. d) The State of Pennsylvania operates an air part iculate sampler at station 2681. Their analyses f or this t ime frame showed normal ambient background levels of gross beta activity and no detectable iodine activity. Based on this investigation, it was concluded t hat the elevated activity was not deposited on the filter during t he f ield sampling period and t hat the elevated rasults of the subject air particulate filters were not a result of the operation of Limerick Generating Station. These activities were considered erroneous and were not included in the calculations of station or group averages. Detectable gross beta activity was observed at all locations. The values ranged from <.003 to.055 pCi/m3 Ho significant difference in activity was observed between t he cont rol and indicator stations. In addition, concentrations detected were consistent with those observed in previous years (Figure C-5, Appendix C). Gamma Soectrometry Weekly samples were composited and analyzed monthly for gamma-emitting nuclides (Table C-XII, Appendix C). Naturally occurring Be-7 due to cosmetic ray activity was detected in most samples. These values ranged from <.01 to = .46 pCi/m3 K-40, also naturally occurring, was detected in twenty-two samples. These values ranged f rom.02 to.30 pCi/m3 As noted in the previous discussion, four stations g (1781, 20DI, 2651, and 2981) showed detectable I-131 g activity in the January composite. These results were considered erroneous. All ot her nuclides searched for were below the minimum detectable levels. No significant difference in activity was observed between the control and indicator stations. b. Airborne Iodine Continuous air samples were collected from the same seventeen locations as the air particulate samples. However, of the seventeen locations, eight (1053, 11S1, 13C1, 13H4, 1451, 22G1, 31DI, 35B1) were analyzed weekly for I-131. The remaining nine samples were held and.

I analysis was not necessary. Results of t he I-131 analys is are found in Table C-XIII, Appendix C. All results were less than the minimum detectable level. 2. Terrestrial a. tillk Semples were taken from four locations (5C1, 22F1, 1051, and 25B1) bi-weekly during the grazing season (April-I Hovember) and monthly at other times. Samples from 8 additional locations (21B1, 11DI, 17C2, 18C1, 9E1, 11E1, 36E1, and 9G1) were taken monthly. The following analyses were performed: Iodine-131 All milk samples from all locations were analyzed for concentrations of I-131 (Table C-XIV Appendix C). All results throughout this period were less than the minimum detectable level. Gamma Soectremetrv Each milk sample from locations 5C1, 22F1, 1051, and 2551 was analyzed for concentrations of gamma emitting nuclides (Table C-XIII, Appendix C). Quarterly milk samples from I locations 21B1, 11DI, 17C2, 18C1, 9El, 11E1, 36El and 901 were analyzed for concentrations of gamma emitting nuclides (Table C-XV, Appendix C). With the except ion of naturally occurring K-40, all nuclides searched for were below the minimum detectable level. The values for K-40 ranged from 990 to 1700 pCi/1. I I I I

I b. Well Water Samples were collected from two locations 1151 (indicator) and 18Al (control) semi-annually. The following analyses were performed: Tritlum Total samples f rom both locat ions were analyzed f or aqueous tritium activity (Table C-XVI. Appendix C). Tritium activity (140 pCi/1) was detected in one sample from control station 18A1. This activity is below t he required sensitivity f or this analysis and is not an ef f ect of the Station discharges. Gamma Soectrometrv Total samples f rom bot h locat ions were analyzed f or gamma emitting nuclides (Table C-XVI, Appendix C). All nuclides searched for were below the minimum detectable level. c. Veaetation Vegetation samples were collected from one location (1151) monthly during the growing season (April-Hovember). The following analysis was performod Gemma Soeetremetrv Vegetation semples were analyzed for gamma emitting nuclidos (Table C-XVII Appendix C). The nuclides detected were Be-7 ranging from <.02 to.34 pCi/g (wet) and naturally occurring K-40 ranging from.24 to 6.3 pCl/g (wet 2. Bo-7 is due to cosmic ray activity. All other nuclides were less t han

he min imum detectable level.

d. fultes A rabbit sample was collected annually from one location l (2655) and t he following analysis was performed: Gemma Spectrometrv Rabbit flesh was analyzed for gamme emitting nuclides (Table C-XVIII. Appendix C). A!! nuclides searched for E were less t han the minimum detectable level with the g exception of naturally occurring K-40, which had a value of 4.2 pCi/ gram (wet). I I 1

i I C. Ambient Gamma Radiation l Ambient gamma radiation levels were measured utilizing Ca504: I Tm thermoluminescent dosimeters for the f irst three quarters and CaSO4:Dy thermoluminescent dosimeters f or t he fourth quarter. Ir. addit ion, the data prior ta the f ourth quarter were originally reported in the units of mrad /std. month but I converted to the unit s of mR/std month using the conversion factor of 0.955 mrad /mR. This is the same conversion used in the original calculation of the results (soo Appendix D) and I provides consistent units f or comparison with the f ourt h quarter results. Forty-eight TLD locations were established around the site in a three ring concept for comparison purposes an " inner ring" of sixteen locat ions around the site I boundary; a " middle ring" of twenty seven locations within a ten mile radius of the site; and an " outer ring" of five locat ions at distances outside the ten mile radius of the site. I Results of TLD measurements are listed in Tables C-XIX to C-XXII, Appendix C. The majority of the TLD measurements were below 10 mead /std. month, wit h a range of 4.52 to 12.13 mR/std. month. No significant differences were observed among the results from the site, middle, and outer rings (Table C-XII, Appendix C). In addition, levels measured were consistent with those observed in previous years (Figure C-6 Appendix C). I I I I I I 19 - I

I ENVIRONMENTAL DOSIMETRY PAHASOHIC UD2OOS By TI definition, a thermoluminescent dosimeter (TLD) is considered one end of a capillary tube containing calcium sulfate (Tm) powder as t he l thermoluminescent material. This material was chosen for its 5 characteristic high light output, minimal thermally induced signal loss (fading), and negligible self-dosing. The energy response curve has been flattened by a complex multiple element energy compensating shield supplied by Panasonic Corporation, manufacturer 3f t he TLD reader. T here exists f our dosimeters per station sealed in a p tyethylene bag to demonstrate integrity at the time of measurement, and for visualization l of the sample placement instructions. The zero dose is determineo from W TLDs located in the lead shield at Toledyne Isotopes, Westwood, New J=rsen Following the predesignated exposure period the TLDs are placed in the TLD reader. The reader heats the calcium sulf ate (Tm) and t he measured light emission (luminescence) is used to calculate the W environmental radiation exposure. Data are normalized to standard machine condit ions by correct ing machine settings to designated values before readout. Data are also corrected for in-transit dose using a set of TLDs kept in a lead shield in the field, exposed only during transit. The average dose per expssure period, and its associated error is t hen calculat ed. A Cs-137 source is used to expose TLDs as a ref erence sample. An absorbed dose in tissue is determined using the 0.955 rad / Roentgen conversion factor and dose equivalent (mrem) by using a quality factor of 1.

m I ENVIRONMENTAL D051 METRY TELEDYHE ISOTOPES Telodyne Isotopes developed a thermoluminescent dosimeter which is a rectangular shaped teflon wafer impregnated with 25% Ca504:Dy phosphor. The dosimeters are annealed in a hot air oven prior to use and are 5 inserted into black polyethylene pouches. The filled pouches are labeled and placed in rectangular holders which contain copper shielding to filter out low energy radiation. Af ter exposure in the environment, four separate areas of the dosimeter are read in a Telodyne Isotopes model 8300 TLD reader. The dosimeter is then re-irradiated by a standardized l Cs-137 source and the f our areas are read again. Calculation of the environmental exposure is performed by computer, using t he re-irridiat ion W readings to determine the sensit ivity of each area of the dosimeter. The transit dose is determined f rom TLD's located in the lead shield at Telodyne Isotopes. Westwood, How Jersey and from TLD's kept in a lead shield in t he f ield. The error is then calculated end subtracted from the gross reading. Calculation of results (a) For any given area of t he dos imet er, the dose in mR is calculated by the formular AVCOHTROL DO5E = R REDOSE RR Where R k initial reading of the area RR = second reading of the area (after re-irradiatlon) REDOSE = re-irradiation dose in mR average of control values calculated AVCONTROL : as explained below. If no controls are used, AVCONTROL = 0 and gross exposures result. I (b) Each area of each control is calculated as follows: CDOSE CR CREDOSE CRR / Where: CDOSE

(d) Using the criteria that if one standard deviation is greater I then 10% of the average of the f our 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 oliminated and the results will be based on t he remaining areas.

I DETERMINATIDH OF GAMMA EMITTING RADIDISOTOPE5 TELEDYNE ISOTOPE 5 Gamma emit t ing radioisotopes are determined with t he use of a lit hium-drif ted germanium (Ge(LI)) and high purity germanium detectors with high resolution spectrometry in specific media, for example, air particulate filters, charcoal filters, milk, water, vegetation, soll/ sediments, biological media, etc. Each sample to be assayed is prepared and counted in standard geometries such as one liter wr,ap-around Marinelli containers, 300 ml or 150 ml bottles, or two-inch f ilt er paper source geometries. Samples are counted on large (>55 cc volume) Ge(LI) detectors connected to Muclear Data 6620 data acquisition and computation systems. All resultant spectra are stored on magnetic tape. The analysis of each sample consist s of calculat ing t he specif ic activities of all detected radionuclides or the detection limits from a standard list of nuclides. The Ge(LI) systems are calibrated for each standard geomet ry using cert i f ied radionuclide standards t racerble to t he Hattonal Bureau of Standards.

I A detection limit (MDL) or "less than" (LT) value is reported if no activity is found. If no spectral lines are identified at the energies appropriate to a nuctido. the LT value is calcutated by the above equation. If spectral lines are ident i f ied but t he 2 sigma error in t he I first equation is greater than 60% of the net activity, than a LT value is also assigned by the second equation. I The analyst's judgement is exercised in the decision to report an activity or an MDL. The agreement between various spectral lines of the same nuclide, and possible interface from ot her nuclides, are considered in this decision. I I I I I I I I I

Four liters of sample are first equilibrated with stable lodido carrier. A batch treatment with anion exchange resin is used to remove iodide f rom the sample. The lodine is then stripped f rom the resin with sodium hypochlorite solution, reduced wit h hydroxylamine hydrochloride, l and extracted into carbon tetrachloride as free lodine. It is t hen back-E extracted as iodide into sodium bisulfite solution. The iodido sample solution is oxidized to the f ree state using HaHO reagent and is extracted several times into a total of 15 ml of toluene. A 200 Mrwnllquot is taken for determining chemical yield by l spectrophotometer. A decolorizing agent (2 methyl-2-butene) is added to t he toluene-iodine solut ion to f orm en inert molecule and to minimize W l!:;uld scint illat ton quenching. A toluene-based 1Iquid scintillation counting solution is added to t he sample, which is then analyzed by a beta gated gamma coincidence counting system. I I I I I I I I I

Calculation of the MDL I If the not activity (previously defined) is less than a specified mult iple of the background count ing error, the activity on the collection date is below t he limits of detection and is called "less than" (L.T.) or " minimum detectable level" (MDL). The L.T. value can be specified by stat ing only the count ing error at a predetermined multiple (Om) of t he one sigma stat ist ics. A sigma I multiple (Gm) of 4.66 is used for calculation of the L.T. values unless anot her mult iple such as 2.83 is specified. I Gm t hu s L. T. : at (2.22(v)(y)(DF)(C) I I I I

I I DETERMINATI0H OF GROSS ALPHA AHD/OR BETA ACTIVITY IN WATER SAMPLES. AIR PARTICULATE FILTERS, OR SEDIMENT I This describes the process used to measure the overall alpha and/or beta radioactivity of water samples, air particulate filters, composite air particulate filters or sediment without ident i f ying t he radioact ive l I species present. No chemical separation techniques are involved. One liter of the water sample is evaporated on a hot plate. The sample is rinsed inte a 2-inch diameter stainless stool planchet which is I stamped with a concentric ring pattern to distribute residue evenly. Final evaporation to dryness takes place under heat lamps. Residue mass is determined by weighing the planchet bef ore and af ter mounting the I sample. In the case of air particulate sample, the filter is mounted directly on a 2-inch stainless steel planchet. Sediment samples are dried and a 1 gram aliquot is mounted directly on a 2-inch stainless steel planchet. The planchets are then counted for alpha /and or beta activity in a low background gas flow proportional counter. Calculation of activity I includes an empirical self-absorbtion correction curve which allow for the change in ef f ective counting ef ficiency caused by the residue mass. Self absorbtion is not considered in the case of air part iculate filters because of the impracticality of accurately weighing the deposit and I because the penetration depth of the deposit into the filter is unknown.

r i I I t.PPENDIX E: QUALITY COH1ROL PROGRAM l TI participates in the EPA radiological interlaboratory comparison 1 (cross check) program. This participation includes a number of analyses on various sample media as found in the Limerick Generating 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. During the time period of this report. 94 of the 98 samples analyzed fell within the EPA mean and standard deviations. Table E-t I summarizes the results of all 1985 samples. The second quality control program includes the analysis of blank I and spiked semples. This intrataboratory program indicates the proper functioning of the chemistry and instrumentation for gross alpha, gross beta, lodine-131, strontium 89-90, gamma and t he tritium analyses. Of the 708 analyses published during the period of this report, 21 were I determined to be outside the expected range. Five of them were inadvertently not spikod, seven were low due to minor chemistry problems and nine contained trace amounts of activity f rom tap water or f rom hood contamination. All anomalies were investigated and resolved. Another quality control program which Teledyne Isotopes participates in conjunction with the Limerick REMP is a duplicate I analysis program. The duplicate or replicate samples are prepared in the field from samples that are as homogenous as possible, such well-stirred or mixed liquids or solids. Of the 220 duplicate / replicate samples published in 1985, 216 were considered to be in agreement wit h t he original result. Three of the samples which were not in agreement, were air particulate (AP) samples. One of those AP samples was part of the group of anomalous results discussed in the results and discussion I section. The other two AP dif f erences are probably due to dif f erent filter loadings resulting f rom the replicate nature of the samples and the different elevations of the sample equipment. The final sample which was not in agreement was a surf ace water sample and the dif f erence was due to improper field preparat ion of the duplicate sample. I I I I I

Units are pC1/f for water, urtne, and milk except K is in og/l. Units are total pct for air particulate filters. (b) Teledyne Results - Average i three sigma. Units are pC1/2 f or water, urine, and milk except K is in og/f. Units are total pct for air particulate filters. (c) Units for food analysis are pct /kg except K which is ag/kg. (d) The results f rom the EPA mere received on August 09, 1985 for the analysis completed in April. The EPA had difficulty determining the Correct results for this sample. It was difficult to scavenge and the results were reported as a courtesy although they were considered suspect because of the difficulty of analyzing a synthetic food sample. (e) A new chemistry was tried but did not give good results. A further refinement of the chemistry is planned. (f) The proportional counters are calibrated for alpha efficiency with An-241. Low energy alpha emitters are included in the spike; however, no correction for eff1ctency was made. (g) The proportional counters are calibrated f or beta ef ficiency with Cs-137. The efficiency Correction applied for the low energy beta emitters overcompensated because the amount of the low energy emitters was small compared with the high energy emitters.

(h) The low Sr-90 results were caused by erroneously high Sr-89 yields because of trace calcium and barium in the precipitated mount. Experiments will be conducted to eliminate this problem. (1) The three results were 50, 55 and 56 pC1/4. The one low result of 50 caused the average to be below the two sigma normalized deviation from the known. (j) A new NB5 traceable standard was prepared to Check the efficiency calibration of the 25 coated alpha counters used to count Ra-226. (k) Final results were not released to Teledyne Isotopes. (1) The results for these samples showed high variability with some results near the spike value, in the future samples will be counted longer and sooner after milk time to reduce the amount of ingrowth correction of Sr-90 into Sr-89. (a) The weight of the sample analyzed will be controlled more carefully since the density may vary from sample to sample. (n) The reported results were 21, 20 and 19. If the cout. ting error (t 1.0) ts taken into consideratton, these results would have been within the two sigma normalized deviation from the known. (o) The reported results were 23, 25 and 28. The one high result of 28 caused the average to be above the 2 sigma normalized deviation from the known. (p) There was a significant difference between the known value and the grand average, therefore, the EPA deleted the results from the final report. (q) Low results were caused by a misunderstandtng of the dilution instructions by the analyst. Samples were diluted by 2. M M M M M M M M M M M M M M
