POINT BEACH ENVIRONMENTAL RADIOACTIVITY SURVEY 4

INTRODUCTION This report is prepared under U.S. Nuclear Regulatory Commission Contract NRC 30-83-647 by the State of Wisconsin, Department of Health and Social Services, Section of Radiation Protection. This report covers the calendar year 1986. Results of environmental radioactivity monitoring are listed in tabular form. The data presented consists of duplicative sample analysis such as air and TLD data and split sample analysis conducted by the state radiation protection laboratory or subcontractor and the licensee. A brief description of sample collection techniques and analytical procedures conducted by the state laboratory is also given. A sample collection summary f or 1986 is included in Table 5. The sample summary includes type and number of samples collected, Minimum Detectable Concentrations ( MDC's ) or Lower Limits of Detection (LLD's) as well as the range of reported activities for each type of sample analysis.

SAMPLING TECHNIQUES Direct Radiation - Thermoluminescent Dosimeters (TLD's)

Continuous monitoring of direct radiation is performed quarterly using thermoluminescent dosimeters. The dosimeters are placed at 43 locations in the area of the Kewaunee and the Point Beach nuclear power plants.

Air Samples Continuous air samples are collected weekly f rom two stations. Air particulate samples are collected on 47 mm. glass fiber filters. Air iodine samples are collected using charcoal absorbers mounted in tandem with the air particulate filters. The nominal sampling rate is 1 - 2.5 cubic feet of air per minute.

Surface Water A split sample consisting of 3.5 liters of liquid effluent is collected monthly at a point close to the discharge of the Point Beach effluent channel. This sample is a monthly composite of weekly grab samples and is collected while the plant is discharging liquid to the channel. A background surf ace water sample is also taken at the Green ssttio=-aoto*.15e 12 ""t ^ urte *r P2-O aveuP i from the Coast Guard Station, 4.8 miles SSE, is included as a background sample for Point Beach.

QUALITY ASSURANCE O

The analysis of the samples is perf ormed under subcontract with the SLH maintains its own quality State Laboratory of Hygiene (SLH).

assurance program which was also reviewed by the NRC in January, 1985.

Analytical procedures provide for routine replicate analyses to verify methods and instrument operation. Traceable sources are used to regularly calibrate the counters and daily performance checks are made between calibrations. In addition, quality control charts are maintained on the counters.

SLH participates in the EPA Cross Check program. The quality assurance progam that the SLH participates in include analysis of blind samples, air filters, food, milk, gamma in water, alpha-beta in water, lodine in water, strontium in water and tritium in water. The EPA Cross Check code f or SLH is "AF". A complete listing of the EPA Cross Check results for 1985 and 1986 is included in Table 6.

SENSITIVITIES AND ERROR - WISCONSIN DHSS Following the recommendations of the Health Physics Society, detection limits will be expressed as a minimum detectable concentration (MDC).

The minimum detectable concentration or MDC is an "a priori" estimate of the capabliity for detecting an activity concentration by a given measurement system, procedure, and type of sample. The MDC should not be viewed as an absolute activity concentration that can or cannot be detected. Minimum detectable concentrations (MDC) are based on the analysis performed and for gamma isotopic analysis have been calculated for a zero decay time. Minimum detectable concentrations (MDC's) are listed in Table 5.

The WI DHSS definition for minimum detectable concentration follows closely the equation for the lower limits of detection as defined in Activities defined by the equation the NRC contract NRC-30-83-64 7.

f or MDC will be used in this report.

The MDC for each radioisotope has been calculated from the following equation:

4.66 sb MDC =

E

• V

• 2.22

• Y *S* exp(-dt)

O Where:

O MDC is the "a priori" lower limit of detection as defined above, as picoeuries per unit mass or volume, sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate, as counts per minute, E is the counting efficiency, as counts per disintegration, V is the sample size in units of mass or volume, 2.22 is the number of disintegrations per minute per picoeurie, Y is the fractional radiochemical yield, when applicable,

. S is the self-absorption correction factor, d is the radioactive decay constant for the particular radionuclide, and t for environmental samples is the elapsed time between sample collection, or end of the sample collection period, and time of counting.

RESULTS AND DISCUSSION A sample collection summary f or 1986 is included in Table 5. The sample summary includes the type and number of samples collected as well as the range of reported activities for each type of sample

. analysis. Results from the individual sample analyses are listed in Tables 7-22.

Radioactive fallout resulting from the Soviet accident at Chernobyl was detected in WT DHSS and Point Beach samples collected during the time period of 00<01/86 - 07/01/86. Sample analysis results are discusted in the individual sections and dose calculations are performed in the section Dose to Individuals from Radioactive Fallout from the Soviet Accident a_t, t Chernobyl.

Air Particulate WI DHSS and Point Beach maintain separate air sampling stations. The indicator site for both WI DHSS and for Point Beach ic located at the residency at the north property line, 1.3 miles NNW. The control site for WI DHSS is located at the Green Bay Pumping Station - Rostok, 15.6 miles NNE. The control site for Point Beach is located at Silver Lake gm College, 17 miles WSW.

O A summary of reported activities by WI DHSS and Point Beach f rom air particulate samples is included in Table 5. Results from the individual sample analyses are listed in Tables 7-10.

The yearly averages, f rom a log-normal distribution, f or the gross beta analysis on the air particulate filters are given in Table 1.

The elevated gross beta activities for the time period of 05/05/86 - g W

06/12/86 are due to radioactive f allout f rom the Soviet accident at Chernobyl. Elevated gross beta activities were reported by WI DHSS and Point Beach and were present in samples f rom both the indicator and the control sites. Elevated gross beta activities were also reported in air particulate samples from the three other WI DHSS environmental monitoring areas.

A summary of reported gamma isotopic activities for WI DHSS and Point Beach from the monthly or quarterly air particulate filter composites is included in Table 5. Results from the individual sample analyses are listed in Tables 11-12.

In the WI DHSS gamma isotopic analysis, bery111um-7 (Be-7) was detected in all composites from both the indicator and the control sites. Bery111um-7 (Be-7) is a naturally occurring radioisotope that is constantly produced through nuclear reactions between cosmic rays and nuclei in the atmosphere. All other radionuclides were below their respective MDC for the 1st, 3rd and 4th quarter composites.

For the 1st, 3rd and 4th quarter composites, Point Beach did not report any activities above their respective LLD. Point Beach does not report naturally occurring radioisotopes and no comparison can be made for the bery111um-7 (Be-7) reported by Wisconsin.

At the observed lower levels of activity the WI DHSS and Point Beach data are comparable in the gamma isotopic analysis of the air Influence by the Point Beach nuclear facility on g'

air quality is not evident when comparing the data from the indicator and control sites.

Radioactive fallout resulting from the Soviet accident at Chernobyl was detected in WI DHSS and Point Beach samples f or the time period of 05/05/86 - 06/12/86. The radioisotopes detected in the WI DHSS sample analysis of the May and June monthly composites of air particulate samples were ruthenium-103 (Ru-103), cesium-134 (Cs-134) and cesium-13 7 (Cs-13 7 ) . The indicated radioisotopes were detected in both the control and indicator composites and the activities f rom both sites are listed in Tables 11-12. The indicated radioisotopes were also detected in air particulate composites f rom the three other WI DHSS environmental monitoring areas within Wisconsin at approximately the same activities.

For the 2nd quarter composites, Point Beach repor.ted activities f or ruthenium-103 (Ru-103) and cesium-137 (Cs-137) for both the indicator and the control sites. Activity for cesium-134 (Cs-134) was less than the Point Beach LLD of 0.01 pCi/M3 The WI DHSS and Point Beach data are comparable in the gamma isotopic analysis of the air particulate samples for the 2nd quarter of 1986.

A summary of reported air iodine activities for WI DHSS and Point Beach is included in Table 5. Results from the individual sample analyses are listed in Tables 7-10.

All reported WI DHSS and Point Beach air iodine measurements except for the time period of 05/05/86 - 06/12/86 were below the required NRC LLD of 0.07 pCi/M 3 for both the indicator and the control sites.

Radioactive f allout f rom the Soviet accident at Chernobyl was detected in WI DHSS and Point Beach air iodine (I-131) measurements. The weekly air iodine (I-131) activity for the time 3period of 05/05/86 -

06/12/86 was in the range of 0.03 - 0.18 pCi/M for WI DHSS and 0.04 -

0.52 pC1/M 3 for Point Beach. Air iodine (I-131) activity was observed at both the indicator and the control sites for WI DHSS and Point Beach. Elevated air iodine (I-131) activity was also observed in the three other WI DHSS environmental monitoring areas.

All reported activities by WI DHSS and Point Beach are at background levels for the samples taken at the control sites. All reported gamma isotopic activities were less than the respective WI DHSS MDC or the respective Point Beach LLD. Gross beta activities reported by WI DHSS and Point Beach were all at background levels for samples collected at the the control sites. The gross beta yearly average f or WI DHSS of 3.911.5 pCi/ liter and f or Point Beach of 2.910.4 pCi/ liter for the control sites are not significantly dif f erent f rom reported yearly average gross beta activities from previous years.

For samples taken at the indicator site, effluent channel, all reported gamma isotopic activities were less than the respective WI DHSS MDC or the respective Point Beach LLD. Tritium (H-3) was detected by WI DHSS in four monthly composites in the range of 1160 -

19300 pCi/ liter. Point Beach reported tritium (H-3) activities in three quarterly composites in the range of 1660 - 6790 pC1/11ter. The WI DHSS and Point Beach activities f or tritium (H-3) are comparable O when WI DHSS monthly activities were quarterly averaged. WI DHSS reported three iodine-131 (I-131) activities above its MDC of 0.4 9

pCi/ liter. The WI DHSS reported activities f or iodine-131 (I-131) we re 2.911. 6, 2. 4 + 0. 6 and 3. 610.7 pCi/ liter. All reported iodine-131 (I-131) activities for Point Beach were less than 0.5 pCi/ liter. The gross beta yearly average f or WI DHSS of 5.311.6 pCi/ liter and for Point Beach of 2.210.5 pCi/ liter is not significantly different from previous years.

All activities reported by either WI DHSS or Point Beach are below the standards for uncontrolled areas specified in ICRP Report No. 2 or 10 CFR 20. Plant influence is not evident af ter comparing WI DHSS and Point Beach data for the indicator and control sites.

Radioactive fallout from the Soviet accident at Chernobyl was not evident or detectable in surface water samples.

Fish Split samples were taken for fish. The samples were obtained from the Point Beach pumphouse.

A summary of reported activities by WI DHSS and Point Beach f or fish samples is included in Table 5. Results f rom the individual sample analyses are listed in Tables 17-18.

For WI DHSS, the detected levels of activity for cesium-137 (Cs-137) and for naturally occurring potassium-40 (K-40) were also reported in previous years. For Point Beach only cesium-137 (Cs-137) was detected g above its respective lower limit of detection (LLD). Naturally w occurring isotopes such as potassium-40 (K-40) are not reported by Point Beach.

At the low level of reported activities the WI DHSS and Point Beach data are comparable.

Radioactive fallout from the Soviet accident at Chernobyl was not evident or detectable in fish samples.

Shoreline Sediments Split samples were taken for shoreline sediments at three locations.

A summary of reported activities by WI DHSS and Point Besch for shoreline sediment is included in Table 5. Results from the individual sample analyses are listed in Table 19.

From the WI DHSS gamma isotopic analysis, naturally occurring potassium-40 (K-40) and radioisotopes from uranium and thorium decay series were detected in all three samples. Cesium-134 (Cs-134) and cesium-137 (Cs-137) were detected at site E-06 and cobalt-60 (Co-60) was detected at site E-12. All reported activities for cobalt-60 (Co-60), cesium-134 (Cs-134) and cesium-137 (Cs-137) were less than the respective required NRC LLD. g 10

p Point Beach analysis did not detect any radioisotopes above their d respective LLD and does not report naturally occurring radioisotopes such as potassium-40 (K-40).

Radioactive fallout f rom the Soviet accident at Chernobyl was not evident or detectable in shoreline sediment samples.

Milk A split sample is taken f or milk. Milk is collected f rom the Funk farm, 3.8 miles WSW and f rom the Lehrmann f arm, 2.7 miles NNW.

A summary of reported activities by WI DHSS and Point Beach for milk samples is included in Table 5. Results f rom the individual sample analyses are listed in Tables 20-21.

For WI DHSS naturally occurring potassium-40 (K-40) was detected in all of the samples. Activities for iodine-131 (I-131) were less than the WI DHSS MDC of 0.4 pCi/ liter except for the 01/08/86 and 03/12/86 samples from the Funk farm and the 06/05/86 sample from the Lehrmann farm. The 01/08/86 and 03/12/86 reported iodine-131 (I-131) activities from the Funk f arm are not statistically dif ferent from the reported Point Beach activites of <0.5 pCi/ liter and are less than the required NRC LLD of 1.0 pCi/ liter. The 06/05/86 reported iodine-131 (I-131) activity from the Lehrmann farm is due to the radioactive t')

fallout from the Soviet accident at Chernobyl and was also reported by

\d Point Beach. Iodine-131 (I-131) was also detected in milk samples from the other WI'DHSS environmental monitoring areas. The detected activity for cesium-134 (Cs-134) from the 09/03/86 sample from the Funk f arm of 14 pCi/ liter is only slightly above the WI DHSS MDC of 12 pC1/ liter, was not reported by Point Beach and is less than the required NRC LLD of 15 pCi/ lites.

Point Beach did not detect any isotopes above their lower limits of detection in its gamma isotopic analysis. Reported results for iodine-131 (I-131) were less than 0.5 pCi/ liter except for the 05/14/86 sample from the Funk farm and the 05/19/86 and 06/05/86 samples from the Lehrmann farm. The 05/14/86 reported iodine-131 (I-131) activity from the Funk f arm is not statistically dif ferent from the WI DHSS MDC of 0.4 pCi/ liter. The 05/19/86 reported iodine-131 (I-131) activity f rom the Lehrmann f arm can not be compared since it was not a split sample. The 06/05/86 reported iodine-131 (I-131) activity f rom the

' Lehrmann farm is comparable with the reported WI DHSS activity.

Naturally occurring potassium-40 (K-40) is not reported by Point Beach.

Influence by the Point Beach nuclear f acility is not evident af ter reviewing the WI DHSS and Point Beach data.

Vegetation - Food Products Point Beach does not sample for food products. A split sample f or vegetation was taken at four sites.

A summary of reported activities by WI DHSS and Point Beach for vegetation samples is included in Table 5. Results from the h

individual sample analyses are listed in Table 22.

In the WI DHSS gamma isotopic analysis naturally occurring potassium-40 (K-40) was detected in all fo.r samples and cesium-137 (Cs-137) in the sample from site E-06. Act2vities f or iodine-131 (I-131) were ,

below the WI DHSS MDC of 60 pCi/kg.

Point Beach does not report naturally occurring radioisotopes. Only cesium-137 (Cs-137) was detected in the sample from site E-06 and was comparable with the WI DHSS reported activity. Activities for iodine-131 (I-131) were below the Point Beach LLD of 80 pCi/kg.

Influence by the Point Beach nuclear f acility is not evident af ter reviewing the data for WI DHSS and Point Beach.

Radioactive fallout from the Soviet accident at Chernobyl was not evident or detectable in the vegetation samples collected at this time.

Dose to Individuals from Gaseous and Licuid Effluents Dose calculations for gaseous and liquid effluent releases were performed according to the mathematical models illustrated in USNRC Regulatory Guide 1.109, " Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose The of Evaluating doses, listed in Compliance with 10 CFR Part 50, Appendix I".

Table 2. were calculated f or the maximum exposed individual f or WI DHSS samples with activities greater than MDC and background levels.

Doses resulting from gaseous and liquid effluent releases are in compliance with 10 CFR Part 50, Appendix I.

Dose to Ind5viduals from Radioactive Fallout from the Soviet Accident M Chernoby; Dose calculations were performed on samples collected af ter the Soviet accident at Chernobyl. Radioactive fallout was detected in air particulate and air iodine samples during the period of 05/07/86 -

06/12/86, in milk samples during the period of 05/14/86 - 06/30/86 and in vegetation samples collected in early June, 1986.

Air particulate and air iodine reported activities by WI DHSS were uniform over the four environmental monitoring areas within Wisconsin and the average activities f rom the f our areas were used in the dose calculations. Air particulate and air iodine activities returned to and remained at background levels after 06/30/86.

Analysis of vegetation samples collected 06/02/86 f rom the WI DHSS LACBWR environmental monitoring area had detectable activities f or ruthenium-103 (Ru-103), lodine-131 (I-131) and cesium-137 (Cs-137) in 12

n approximately the same proportions as those reported in air Analysis of vegetation samples collected in

() particulate composites.

September and October from the four WI DHSS environmental monitoring areas had no detectable activities f or isotopes present during the period of 04/28/86 - 06/30/86.

Ground deposition affected only the milk pathway since food products were not ready f or harvest at that time. Milk samples from local

- farms were collected from the four WI DHSS environmental monitoring areas and pooled milk samples were collected f rom six major milk cooperatives within Wisconsin. Iodine-131 (I-131) was detected in a majority of the samples at activities ranging from the WI DHSS MDC of 0.4 pCi/ liter up to 45 pCi/ liter and cesium-137 (Cs-137) was detected in only a couple of samples at activities only sligbt2y above the WI DHSS MDC of 12 pCi/ liter.

Dose calculations were perf omed according to the mathematical models illustrated in USNRC Regula: cry Guide 1.109, " Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the I". The Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix calculated doses represer.t the dose received during the indicated time period due to radioactive fallout from4, the Soviet accident at were calculated for the Chernobyl. The doses, listed in Table maximum exposed individual for WI DHSS samples with activities greater than MDC and background levels. The parameters used in the dose calculations are listed in Table 3.

It is important to note that the doses listed in Table 4 are calculated doses for the exposure periods listed in Table 3 and only represent the dose received f rom exposure to radioactive f allout from the Soviet accident at Chernobyl. From the doses listed in Table 4 it The is apparent that the dose to the thyroid is the most important.

thyroid dose is due mainly to the detected activity for iodine-131 (I-1 131). m s, The thyroid dose received f rom air iodine (I-131) is anginhalation ,

dose and was calculated from continuous air sampling. The air iodine (I-131) activity 21sted in Table 3 is the average activity from four weekly samples.

The thyroid dose from milk is an ingestion dose calculated from detected activities f or lodine-131 (I-131) from grab milk samples.

Iodine-131 (I-131) for the listed exposure period in Table 3 was detected in milk samples from within Wisconsin at activity levels of

<MDC (0.4 pCi/ liter) to 45 pCi/ liter. One mi'1k ' sample collected from a local farm by the LACBWR nuclear generating facility had a iodine-131 (I-131) activity of 70 pCi/ liter. The activity for iodine-131 (I-131) of 45 pCi/ liter listed in Table 3 is probably greater than the average activity detected during the indicated time period but was used for calculation purposes as a worst case possibility.

The activities for iodine-131 (I-131) detected in milk samples is less Q than the U.S. Food & Drug Admi nis t ra t ion's (FDA) Preventative C Protective Action Guides (PAG's) which would require public health officials to take action to prevent food stuffs from entering commerce 13

~

.w

if the PAG is exceeded. The FDA PAG's were set up for short-term emergencies such as the Soviet accident at Chernobyl. The FDA Preventative PAG f or iodine-131 (I-131) is 15000 pCi/ liter f or peak activity in milk.

The U.S. Environmental Protection Agency's (EPA) limit for iodine-131 (I-131) in water is 3 pCi/ liter'. The EPA limit is more protective than the FDA's Preventive PAG f or iodine-131 (I-131) but this limit was set up for a lifetime consumption of drinking water. Iodine-131 (I-131) was only detected in milk samples for the time period of 05/14/86 - 06/17/86 and it would be difficult to apply the EPA limit for iodine-131 (I-131) in water.

The U.S. Environmental Protection Agency (EPA) in document 40 CFR 190 restricts the annual exposure of the population from all parts of the nuclear fuel cycle, including nuclear power plant. The EPA restriction for annual exposure is 25 millirems to the whole body or any organ, except for the thyroid for which the limit is 75 millirems.

The Wisconsin limits for permissible levels of radiation exposure from external sources in unrestricted areas is defined in theU.S. Wis.Nuclear Adm.

Code section HSS 157.12 which have been taken f rom The exposure limit stated in HSS Regulatory Commission 10 CFR 20.

157.12 is 500 millirem whole body in any one year.

The calculated doses f rom radioactive f allout from the Soviet accident at Chernobyl listed in Table 4 are below current state and f ederal regulations and present little risk to the Wisconsin general public. g
