{{#Wiki_filter:** A. 1986 Palisades Nuclear Plant Annual Radiological Environmental Operating Report Introduction The 1986 Palisades Nuclear Plant Annual Radiological Environmental Operating Report provides a summary and data interpretation of the Palisades Radiological Environmental Monitoring Program as conducted during the 1986 reporting period. Reporting requirements are detailed in Technical Specifications. 4.11, Tables 4.11-1 thru 4.11-3, 6.9.3.1.B and Table 6.9-1. Palisades was off-line for the majority of 1986: being placed in cold shutdown on May 19, 1986 and returned to service April 3, 1987. Prior to May 19, 1986, Palisades was intermittently in-service. There are no remaining 1986 laboratory sample analyses pending (final) completion for inclusion into this report. The results of all environ-mental samples collected are evaluated as follows: 1..

3.

Air iodine and particulates, TLDs (monthly and quarterly), and milk data were statistically evaluated at the 95% confidence level (using SAS program) by the methodology detailed in Palisades Procedure HP 10.4. The data was compared against two criterium: the first criteria is the statistical level which indicates that sample results from near sites are greater than those from control sites, but that the difference is not significanto The second criteria is the reporting level (twice the statistical level) which is_the minimum detectable difference that exceeds zero at the 95% conf i-dence level. Doses to the public are evaluated if the reporting level is exceeded. Well water, lake water intake/discharge, sediment and fish samples were evaluated using a data means comparison against the appropriate control location(s) and Palisades Technical Specification limits. Due to the affect of the Chernobyl nuclear accident fallout on air and milk environmental samples, the foliowing samples were deleted from statistical evaluation: Air iodine and particulate samples 45 samples - near site locations 5-11 thru 6-8-87 15 samples - control locations 5-15 thru 6-12-87 Milk sam:eles 6 samples - near site locations 5-23 thru 7-1-87 2 samples - control locations 5-23 thru 7-1-87 In addi ti' on to the above, special milk samples were collected and analyzed *. Further details about the Chernobyl affected environ-mental samples will be addressed under a separate report heading. S70602023s-S6 l 2:3i-- --------- kDR ADOCK 05000255 PDR IC0587-0152A-HP01 1

B. Discussion and Interpretation of Results

1.

Air Samples Comparison of the airborne particulate sample data between near-site and control locations resulted in the site data exceeding the statistical level for the months of January and March; there were no instances however, of any statistical reporting levels being exceeded. With the exception of 60 Chernobyl affected air samples (all loca-tions) collected between 5-15-86 and 6-12-86, there was no I-131 activity reported above minimum detectable levels. A total of 633 weekly air samples were collected and analyzed, however 75 sample results were deleted from statistical evaluation as follows: 45 sample results - near site locations: Chernobyl fallout 5-11-86 thru 6-8-86 15 sample results - control locations: Chernobyl fallout 5-15-86 thru 6-12-86 6 sample results - near site locations: did not meet LLD due to sample collector error and/or malfunction of equipment. Affected stations were: 5-PR on 2-9-86; 2-TH on 2-16-86; 2-TH on 3-23-86; 3-HS on 8-10-86; 6-RB on 10-26-86; and 7-SD on 12-21-86 *. 9 sample results - control locations: did not meet LLD due to sample collector error and/or malfunction of equipment. Affected stations were: 11-KZ on 1-23-86;, 11-KZ on 7-24-86; 10-GR on 7-31-86; 11-KZ on 7-31-86; 11-KZ on 8-7-86; 12-DG on 9-24-86; 10-GR on 9-25-86; 11-KZ on 11-20-86 and 10-GR on 12-25-86. The deleted sample results constitute 11.8% of the collected samples not. used in the statistical evaluation, however with the exception .of the Chernobyl affected samples (addressed separately), only 2.4% of the collected samples were unusable for data evaluation. This is a smaller amount of deleted samples than as reported in the 1985 Palisades Annual Radiological Environmental Operating Report. The deleted sample results do not indicate any significant reduction in the overall sample program. Technical Specification sensitivities were met. Air iodine/particulate samples are collected via an approximate continuous 1 cfm air flow through a gelman 47nm air filter (particu-late sample) and Scott air iodine filter cartridge. Both filters are in-line with each other and housed within the same sample holder

• The 1986 air sample results are consistent with actual effluent releases and site-specific meteorology.

2.

Lake Water A total of 24 individual monthly lake water composite samples were collected.from 2 locations during 1986. Lake water intake and discharge samples are collected daily and composited into monthly samples. Evaluation of the monthly lake water analytical results was based on a data means comparison between plant intake and South Haven drinking water as well as with the Palisades Technical Specification reporting limits. The South Haven drinking water serves as a control. Alpha, gross beta and tritium analyses are required for both lake intake and discharge monthly samples. For all samples, the analyt-ical results were <1.0 pCi/L (LLD) for alpha and <4.0 pCi/L for gross beta (except for the January Lake intake sample at 5.0 pCi/L). The tritium results were <500 pCi/L (LLD) for Lake intake and 1155.0 pCi/L (mean value) for Lake discharge. The elevated mean tritium value for Lake out in 1986 was due to plant effluent discharges. No Technical Specification limits were exceeded. Both Lake intake and discharge are collected daily for composite into a monthly sample. A one-gallon quantity of sample is sent to Teledyne Isotopes for analysis. No treatment of the water samples with a preservative is necessary.*

3.

Drinking Water A total of 24 individual monthly drinking water composite samples were collected from the South Haven Municipal Water System. The samples are obtained from 2 collection points: Lake water intake (raw) and treated water. Samples are collected daily for composite into a monthly sample. Evaluation of the drinking water analytical results was based on a data means comparison between Lake water intake (raw) and treated water as well as with the Palisades Technical Specification report-ing limits. The Lake water intake serves as a control *. The evalu-. ated data was also trend plotted against the Palisades Lake water intake/discharge gross beta results. Both Lake water intake and treated drinking water samples require gross beta analyses. A tritium analysis is required for treated water only. For all samples, the analytical results were <4.0 pCi/L (LLD) for gross beta. All treated drinking water samples were <500 pCi/L (LLD) for tritium. No special or supplemental analyses were necessary during 1986

• A two-gallon quantity of each sample is sent to Teledyne Isotopes for analysis.

No treatment of the water samples with a preservative is necessary. IC0587-0152A-HP01

4.

Well Water A total of 36 individual monthly well water samples were collected from 3 locations during 1986.

• The Pall.sades site well is collected daily and composited into a monthly sample; the State Park and Covert Towship Park well water samples are collected as monthly grab samples only.

Evaluation of the monthly well water analytical results was based on a data means comparison between the Palisades site and the State Park/Covert Township Park samples as well as with the Palisades Technical Specification reporting limits. The State Park/Covert Township Park wells serve as controls. Tritium and_ gross beta analyses are required* for the well water samples. Analytical results were <SOO pCi/L (LLD) tritium for.all locations; and <4.0 pCi/L (LLD) gross beta for the Palisades site and Covert Township Park wells. The State Park well was reported as having 7 monthly samples slightly above the 4.0 pCi/L gross beta LLD, however the 1986 mean value for the State Park well gross beta results was 3.6 pCi/L. The State Park well samples.have tradition-ally had a higher gross beta level than any of the other sampled wells. This has been evaluated in previous reports as not being from power plant origin

• No special or supplemental analyses were necessary during 1986.

Two one-gallon quantities of sample per offsite well and one one-gallon quantity from the on-site well are sent to Teledyne-Isotopes for analysis. No treatment of the water samples with a preservative is necessary.

5.

Milk - A total of SS individual monthly milk samples were collected from 4 different dairy farms (locations 26-GM, 27-KK, 28-GH, 29-CD)o The milk samples are obtained as grab samples only (from dairy milk tanks). Due to the.effects of the Chernobyl nuclear accident, 8* individual milk samples (6-from near-site locations; 2-from control locations) collected during the months of June and July were deleted from the SAS statistical evaluation (Sr-90 and -Cs-137). Trace amounts of - I-131 activity were also present in these sampleso In addition to the above monthly (routine) samples, 7 special milk samples (2-complete sets - 1 per dairy location except for station 29-CD on May

14) were collected between the dates of S-14-86 to 5-23-86.

For further details, refer to the Chernobyl attachment. With the dele-tion of the 8 Chernobyl affected milk samples, only 40 samples were statistically evaluated. IC0587-0152A-HP01 4

Because all other isotopic results were below LLD, only the Sr-90 data was statistically evaluated. *The Sr-90 activity level exceeded the SAS statistical level, but not the statistical reporting level (twice the SAS statistical level). Except for the special Chernobyl. samples, no special or supplemental analyses were necessary. during 1986. Also, the' following milk sample location changes were initiated in late 1986:

a.

Effective 11-9-86, dairy location 26-GM (G. Miller, 4.3 mi SE) was replaced with the F. Crnkovich dairy (7.5 mi NE). This change was due to the G. Miller farm going out of business. Two monthly milk samples were collected at the new location (November and.December samples). No statistical effect was not~d when the F. Crnkovich dairy analytical results were incorporated with the 26-GM analytical results. b~ iffective 12~3-86, control dairy location 29-CD (Constantine Diary~ 48 ~i SE) was r~placed with the W. Shine dairy (10 mi NE). This change was necessary in order that the control dairy location** be within the specified Technical Specification distance limi.ts. Only one monthly milk. sample was collected at the new location (December). Analytical results of the W. Shine dairy December 1986 milk sample are within the same data range as that of location 29-CD. Milk s~ples are required monthly. (usually collected the 1st week of the month) from each designated.location (4 total). Two one-gallon quantities of raw milk (grab sample) are ob-tained per sample location in orqer to meet analytical require-ments. Each sample quantity is treated with a sodium bisulfite (40grams per gallon) preservative prior to being sent to Teledyne.Isotopes. 60 TLDs - Gannna Dose There.was a total of 285 monthly, 95 quarterly and 24 annual TLDs collected and analyzed during 1986. Not included in this amou11t are the following TLDs (with locations) reported as missing/stolen: Monthly TLDs - station 24 - March station 20 - April station 21 - April Quarterly TLDs - station 24 - 1st Quarter It should be noted that for the above locations, spare TLDs were posted as replacements for the longer term TLDs (quarterly, annual) that were stolen at the same time as the monthly TLDs. These TLDs were: IC0587-0152A-HP01 5

Quarterly TLDs - station 20 - new 2nd quarter station 21 - new 2nd quarter .Annual TLDs - station 21 - new annual station 24 - new annual Because monthly TLDs are normalized for 30-days and quarterly TLDs for 91-days, the replacement/spare TLDs that were placed in service are adjusted under this criteria. For purposes of using the SAS statisti'cal program, the missing data for the station 24-lst quarter TLD was calculated using monthly TLD data. The Palisades gamma dose program consists.of 24 locations: 10

• directly on-site; 10 near-site (ringeJ-1~o5 miles out), 3 controls
• (ringed 30-55 miles out) and l TLD control placed in a lead storage cave.

The on-site locations recorded an average of 3.9 mR/month; the near-site locations (middle ring TLDs) recorded an average of 4.5 mR/month; the control locations (remote/outer ring TLDs) re-corded an average of 4.4.mR/month; and the lead cave control TLD recorded an average of 2.2 mR/month. This is consistent with expected results based on actual effluent releases. The. SAS statistical evaluation was accomplished by comparing site/near-site locations. (ST-*01 through ST-09, ST-23 and ST-24) against control locations (ST-10 through ST-12) for both the monthly and quarterly TLD reporting periods. The annual TLD data was evaluated'by direct *comparison of the site/near-site and control locations on a one-to-one basis (due to small.quantity of data used). Location ST~02 (Tower Hill, 5 mi S of reactor site) had the greatest mean for both the 1986 quarterly and annual TLDs. Location .ST"'.'06 (R. Bus, 4.25 mi NE.of reactor site) had the greatest 1986 monthly.TLD mean. Background and intransit gamma exposure levels were accounted for and subtracted from the TLD data prior to statis-tical evaluation.* Monthly TLD results for April and June*exceeded the SAS statistical level, but not the statistical reporting level (twice the SAS statistical level). There were no instances of the quarterly TLDs exceeding any SAS statistical levels. Technical Specification sensitivities were met. Environmental gamma doses are mE!asured monthly 9 quarterly and annually by placement of 3 appropriately identified TLD badges per designated location. Each Teledyne TLD badge contains a 4-zone CaS04 phosphor waffer (the waffer also includes ari additional. backup/reserve read-out zone). Sensitivity for the multi-zone TLDs are 0.5.milliRem with a linear response of 0.1 milliRem to 1000 Rem.

Crops The collection of food crops. and vegetation samples. (when available and in season) is a requirement within the Palisades Radiological Environmental Monitoring Program. Two principal area crops: apples and blueberries, are regularly collected as specified in Technical IC0587-0152A-HP01 6

Specifications. While there are no pre-designated/special locations where food crops are collected, samples are generally obtained from the same areas where the air monitoring stations are located within the E, SE or SSE sectors. The collection of food crops assists in verifying stack effluent deposition patterns. For 1986, 11 crop samples were collected from two locations (7 samples from 4-JS,. 3.5 mi SE and 4 samples from 5-PR, 3.5 mi ESE). Evaluation of sample analytical results was direct. There was no control location* used. Of the isotopic analyses listed on Table HP 10.4-2, only the gross beta resulted in any specific activity (slightly above LLD). All other analyses were less than LLD. The peach sample at location 4-JS had the highest individual mean for gross beta. No Palisades Technical Specification action or reporting levels were exceeded nor were any special/supplemental analyses required during 1986. Food crop samples are required to be collected when available and in season. When collected-, approximately 1 Kg of sample is placed in a sealable plastic bag for shipment to Teledyne Isotopes. No special treatment of the samples with a preservative is necessary.

8.

Sediment A total of 12 individual sediment samples were collected from 5 - locations during 1986. Four (4) sediment samples are obtained from Palisades (discharge, 1/2 mi South boundary, 1/2 mi North boundary and South Haven Beach locations) and two (2) samples from the Ludington control station (South Jetty) semi-annually. Evaluation of the sediment analytical results was based on a data means comparison between the Palisades and Ludington control samples as well as with the Palisades Technical Specification reporting limits. The individual Palisades sample locations were combined into one indicator (site) location for comparison purposes; however if any one individual sample location had a greater specific iso-topic annual mean than the other location(s)f then that location is identified on Table HP 10.4-2. Of the isotopic analyses listed on Table HP 10.4-2, only Sr-89 and the other gamma (non-indicative/non-parameter isotopes) category were less than LLD. All other analyses resulted in trace amounts of activitypresent. The Ludington control location reported a higher annual mean gross beta activity level ti?-an Palisades (site), although the 1/2 mile North boundary location had the highest mean individual sample gross beta results. For all other positive result isotopic analyses, the various Palisades (site) locations reported the greater mean activity levels. No Palisades Technical Specifi-cation action or reporting levels were exceeded, nor were any special/supplemental analyses required during 1986. IC0587-0l52A-HP01 7

Sediment samples are collected semi-annually from each designated location. A one(l) liter quantity grab sample usually is obtained off-shore. No treatment of the samples with a preservative is necessary prior to shipment to Teledyne Isotopes.

9.

Fish A total of 10 individual fish samples were collected from 4 loca-tions during 1986. Five (5) fish samples were obtained from Pali-sades (discharge, 1/2 mile South boundary, 1/2 mile North.boundary) and five (5) samples from the Ludington control station (South Jetty). Fish are collected semi-annually. Evaluation of the fish analytical results was based on a data means comparison between the Palisades and Ludington control samples as well as with the Palisades Technical Specification reporting limits. As with the sediment samples, the individual Palisades sample locations were combined into one indicator (site) location for comparison purposes; however if any one individual sample location had a greater specific isotopic annual mean than the other l.oca-tions, then that location is identified on Table HP 10.4-2. Of the isotopic analyses listed on Table HP 10.4-2, only Sr-90 and gross beta were greater than LLD. The Palisades (site) locations reported equal or less levels than the control location. As a minimum, at least two (2).different fish species ( ie, forage; sport fish, etc) per designated location. per year are.collected. In most cases however, that criteria is exceeded. When caught, a one (1) liter quantity of fish sample is prepared for shipment to Teledyne Isotopes. Each sample is treated with 10 ml of a 10% formaldehyde solution for preservation.

10.

Atjuatic Biota Because of the beach terrain features at Palisades~ other types of aquatic bi.ota (crayfish, periphyton, algae, etc) are unavailable in sufficient quantity to warrant sample collection.

11.

Broad Leaf Vegetation No broad leaf vegetation samples were collected from the surrounding Palisades environs during 1986. The collection of broad leaf vegetation samples serves as a backup and/or alternative sampling media in case any milk sampling location(s) become(s) unavailable. There were.no problems associated with the quantity or quality of milk samples for the 1986 reporting year

C. Assessment of Palisades Operational Environmental Impact In reviewing the 1986 Palisades radiological environmental monitoring data and comparing it to previous operation and pre-operational data, all trending parameters indicate that the operation of Palisades has had an insignificant environmental impact. Since the Chinese stopped the open atmospheric testing of nuclear devices in late 1981-82, environmental background levels of radiation (due to fallout) have shown a continuous decrease. Evidence of an environmental isotopic build-up (attributable to plant effluents) appears negligible as well. It is unknown at this time what the affect will be (if any) of the Chernobyl fallout on aquatic biota and fish. Immediate affects of the fallout were measured in both air and milk samples for about 6 weeks, however as the longer lived isotopes enter the food chain, their measured concentrating factors remain to be determined.

Evaluation of the 60 individual air iodine and particulate sample results (45 samples - near site locations; 1-ST thru 9-TP and 15 samples - control locations; 10-GR thru 12-DG) deleted from SAS statistical evalua-tion are summarized in the attached tables. The following locations recorded the highest mean activity: I-131" 4-JS (3.5 m1 SE) 0.46 pCi/m 3. Gross beta 12-DG (30 mi SSE) 0.14 pCi/m3 Although not statistically evaluated with other radiological environ-mental sample data, the Chernobyl affected data has been incorporated into the Palisades SAS Trending Graphs. Milk Samples Evaluation of the 8 individual milk sample results (6 samples - near site locations 26-GM, 27-KK and 28-GH; 2 samples - control location 29-CD). deleted from SAS statistical evaluation and evaluation of the 7 special (additional collection) milk sample results (2 complete sets - 1 per dairy location except for station 29-CD on May 14) are also sunnnarized in the attached tables. The following locations recorded the highest mean activity: I-131 Sr-90 27-KK (8 mi NE) . 27-KK (8 mi NE) 12.3 pCi/L 4.0 pCi/L Also, locations 26-GM, 28-GH and 29-CD had elevated Ba-La-124 LLDs due to a laboratory counting delay (LLD is <15.0 pCi/L). Because I-131 activity levels are always below LLD levels, the isotope is not a st*andard data entry.to the SAS Statistical program nor is it trend plotted. The Chernobyl affected Sr-90 results were, however incorporated into the regular Palisades SAS Trending Graphs. IC0587-0152A-HP01 lL

This letter is to notify the NRC of Consumers Power Company's intention to report any anomalous.environmental radioactivity measurements made at our Palisades and Big Rock Point Plants that can reasonably be assumed to have resulted from the Soviet nuclear power plant (Chernobyl) event. This letter also provides specific data that we obtained from performing measurements. of members of a Michigan.tour group which visited the region of the Chernobyl Plant shortly after the event occ1,1rred. The normal environmental monitoring program (EMP) at our Palisades and Big Rock Point Plants has.been augmented,

• as of May 5 and 8, 1986 respectively, to include the collection and analysis of air samples from the iDDDediate plant site.

No anomalous results from the normal EMP measurements made at both plants have been noted to date. The augmented air monitoring activities at the Big Rock Point Plant have not indicated any abnormal results and will most likely be terminated at the end of the week of May 12, 1986 *. The augmented air sampling conducted at the Palisades Plant has, however, yielded increased iodine-131 measurements (I-131 is not normally detected). While these results are clearly due to the Chernobyl event, the levels are so low as to not cause any health hazard to Plant site employees. This information is presented below in the format specified by Information Notice 86-32.

Statistic.al data: (I-131 concentration) a) 3.88E-4nCi/m3; 1 sigma*+/-0.60E-4nCi/m3; one sample b) 8.16E-4nCi/m3; 1 sigmam+/-l.63E~4nCi/m3; one sample 2 Wholebody counts were performed at our Palisades Plant on members of a Michi-gan tour group known to have visited the Kiev, USSR, area following the Chernobyl event. (This group was in the Kiev area from the early "morning of April 30, 1986 through noon of May 2, 1986.) Spectral analyses (gamma) of contaminated personal items were also carried out on May 7, 1986, and both measurements indicate the presence of a wide distribution of fission products. The NRC was notified on May 7, 1986, in accordance with 10CFRS0.72(b)(vi), that these measurements were made and that some internal and external radioac-tive contamination was found. The attached tables provide a summary of these measurements. Table I gives a* typical wholebody count result, and Table II gives very simi-lar results for a particular personal item (a contaminated purse).; We have concluded that the data for the purse differs from the wholebody count results for at least two reasons:

1) the purse was counted with laboratory equipment able to identify a larger number of nuclides, and 2) biological elimination resulted in the purse retaining more of its initial activity than the indivi-duals themselves.

Table III is a list of personal items from the tour group that were checked for radioactive contamination. The highest contaminated items were disposed, in accordance with the owners' requests, as Plant radio-active waste. None of the personal items, with the possibl~ exception of the shoes which were contaminated to such a level as to yield a 32 mrad/hr-beta dose, posed* any potential hazard to the owners. Accordingly, Consumers Power Company health physicists concluded that radiation doses to the lungs and thyroids of the exposed individuals are not medically significa~t. Consumers Power Company continues to make wholebody counting services avail-able to individuals determined to have been contaminated or otherwise signifi-cantly exposed to radiation from the Chernobyl event. This is being accomplished by referral from hospitals or the Radiological Health Section of the Department of Public Health of the State of Michigan after screening by . professionals employed by these organizations. Consumers Power Company has also volunteered to provide an additional wholebody count* for any of the tour group members who chose to return within a week.. These additional counts.. should allow us to make a better estimation of the body burden at the time of exposure, ie, the period while these individuals were in Kiev.

The supplemental environmental radioactivity data provided in this report was obtained by a combination of special request and routine samples collected at Big*Rock Point and Palisades in support of the Radioactive Environmental Monitoring Programs (REMP). Big Rock Point Technical Specification 13.2.1.b and Palisades Technical Specification 4.11.1.b dictate that when the level of radioactivity as the result of plant effluents* in an environmental sampling medium at a specified location exceed the NRC reporting levels (when averaged over any calendar quarter), then a Special Report shall be prepared and submitted to the Commission within thirty (30) days. This report fulfills the Technical Specification requirement, even though the reportable levels of radioactivity are the result of the Chernobyl nuclear.accident. Data from this report will _ be incorpora~ed in the 1986 Annual Radiological Environmental Operating Reports for Big Rock Point and Palisades. The following analytical results are from air charcoal, air particulate and milk samples: Big Rock Point Nuclear Plant, Charlevoix, Michigan Air charcoal/particulate (gamma spectroscopy): iodine-131 and gross beta Sample period: 5/8/86 to 5/15/86 Near-site stations 1 2 3 4 Control stations

1.0 INTRODUCTION

The following constitutes the current Monthly Progress Report for the Radio-logical Environmental Monitoring Program conducted at the Palisades Nuclear Generating Plant, Covert, Michigan. Results of completed analyses are pre-sented in the attached tables. Missing entries indicate analyses that are not completed and the results will appear in subsequent reports. Data obtained in the program are well within the ranges previously encountered in the program and to be expected in the environmental media sampled. None of the media sampled this month contained radioactivity attributable to the operation of Palisades Nuclear Generating Plant. For all gamma isotopic analyses, spectrum is computer scanned from 80 to 2048 KeV. Specifically included are Mn-54, Co-58, Fe-59, Co-60, Zn-65, Zr-95, Nb-95, I-131, Ba-La-140, Cs-134, and Cs-137. Naturally occurring gamma-emi tters, such as K-40 and Ra daughters, are frequent 1 y detected but not listed here. Data listed as 11< 11 are at the 4.66 sigma level, others are 2 sigma. . Unless noted otherwise, the less than value ( 11< 11 ) reported under "Other Gammas" is for all required gamma emitters

Appendix A Interlaboratory Comparison Program Results Teledyne Isotopes Midwest Laboratory (formerly Hazleton Environmental Sciences) has participated in interlaboratory comparison (crosscheck) programs since the formulation of its quality control program in December 1971. These programs are operated by agencies which supply environmental-type samples {e.g., milk or water) containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent. check on the laboratory's analytical procedures and to alert it to any possible problems. Participant laboratories measure the concentrations of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the control 1 imits indicate a need to check the instruments or procedures usedc The results in Table A-1 were obtained* through participation in the envir.on-

• mental sample crosscheck program for milk, water, air filters, and food samples during the period* May.1984 through November 1986 *. This program has been-conducted by the U. s. Environmental Protect ion Agency Intercompar;.son and

- Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support Laboratory, Las Vegas, Nevada. The results in Table A-2 were obtained for thermoluminescent dosimeters {TLD

• s) during the period 1976, 1977, 1979, 1980, and 1981 through part i-cipation in the Second, Third, Fourth, and Fifth International Intercomparison of Environmental Dosimeters under the sponsorships listed in Table A-2Q Table A-3.lists results of the analyses on in-house spiked samples.

Appendix B Data Reporting Conventions

4.0. Computation of Averaaes and Standard Deviations 4.1 Averages and standard deviations listed in the tables are computed from all of the individual measurements over the period averaged; for example, an annual standard deviation would not be the average of quarterly standard deviations. The average x and standard deviations of a set of n numbers x1, xz,... Xn are defined as follows: x=l:tx n s =

t (x-X)2 n-1,

4.2 Values below the highest lower limit of detection are not included in the average. 4.3 If all of the values in the averaging group are less than the highest LLD, the highest LLD is reported. 4.4 If all but one of the values are less than the highest LLD, the single value x and associated two sigma error is reported. 4.5. In rounding off, the following rules are followed: 4.5.1. If the.figure follo~ing those t~ b~ retained.is less than 5, the figure is dropped, and the retained figures are kept unchanged. As an example, 11.443 is rounded off to 11.44. 4.5.2 If the figure following those to be retained is greater than 5, the figure is dropped, and the last retained figure is raised by 1.

• As a~ example, 11.446 is rounded off to 11.45.

4.5.3. If the figure following those to be retained is 5, and if there are no figures other than zeros beyond.the five, the figure 5 is dropped11 and the last-place figure retained is increased by one if it is an odd number or it is kept unchanged if an even number. As an example, 11.435 is rounded off to 11.4411 while 1L425 ;s rounded off to 11..42. B-3
