,m STATE OF WISCONSIN 1986 LA CROSSE BOILING WATER REACTOR ENVIRONMENTAL RADIOACTIVITY SURVEY 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 6. The sample summary includes type and number of samples collected as well as the range of reported activities for each s 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 29 locations in the area of the La Crosse Boiling Water Reactor (LACBWR) nuclear power plant.

Air Samples Continuous air samples are collected weekly f rom two stations. Air particulate samples are collected on 47 mm. glass fiber filters. Air l

iodine samples are collected using charcoal absorbers mounted downstream of the air particulate filters. The nominal sampling rate is 1 - 2.5 cubic f eet of air per minute.

Surface Water A split sample is collected monthly at a point close to the discharge of the LACBWR ef fluent channel, 0.1 mil e W. This sample is a grab sample and is collected while the plant is discharging wastewater to the channel. A background surface water sample is also collected

]' monthly from Lock and Dam #8, 0.7 mile N.

i Milk O

A raw, split milk sample is collected monthly f rom one of three local farms located in the Genoa, Wisconsin area.

Sediment Sediment is collected from three locations in the Mississippi River

  • channel on a semi-annual basis.

Fish Game and scavenger fish are collected periodically from locations in the Mississippi River near the LACBWR nuclear power plant.

Food P_raducts A tl'anded sample of mixed vegetables was collected from a local ga den.

ANALYTICAL PROCEDURES The procedures given are abstracted to present only the basic steps.

The analysis of the samples has been subcontracted to the State Laboratory of Hygiene. A detailed description of the procedures used is available from the State Laboratory of Hygiene.

Direct Radiation Thermoluminescent dosimeters are supplied by the U.S. Nuclear Regulatory Commission. The exposed TLD's are shipped to NRC Region I and are read by the Commission.

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

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-betaThe in water, iodine in water, strontium in water and tritium in water.

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 8.

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 capability 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 f or a zero decay time. A listing of the WI DHSS MDC values is included in Table 6.

4

The WI DHSS definition for minimum detectable concentration follows bp, closely the equation for the lower limits of detection as defined in the NRC contract NRC-30-83-647. Activities defined by the equation 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)

Where:

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 I' ate of a blank sample as appropriate, as counts per n.inute, 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.

Guidelines adopted by the U.S. Environmental Protection Agency are @

used in the reporting of specific analyses. Results f rom specific analyses will be reported whether the results are negative, zero, or positive. Caution should be exercised in the interpretation of ,

individual negative values. While a negative activity value does not have physical significance, it is significant when taken together with other observations which indicate that the true value of a -

distribution is near zero. This procedure will allow all of the data to be reported and will allow a statistical evaluation without an arbitrary cutoff of small or negative numbers. An estimation of bias in the nuclide analyses is then possible as well as a better evaluation of distributions and trends in the environmental data. It is important when reviewing the data in the following tables to compare the reported result to the actual minimum detectable concentration (MDC) for that analysis.

Results for specific analyses will be reported as an activity followed by an error term for that analysis. The error term is a plus or minus counting error term at the 2 sigma (95%) confidence interval and is printed as (+ /-) .

SENSITIVITIES -

LACBWR Lower limits of detection (LLD) or minimum detectable activity (MDA) as reported by LACBWR are defined in their manual LACBWR, HEALTH & .

SAFETY DEPARTMENT PROCEDURE, LACBWR ENVIRONMENTAL MONITORING PROGRAM.

The method for calculating the LLD and a representative table of LLD's for LACBWR is included in this report. In most cases, reported activities for LACBWR are less than the required Nuclear Regulatory Commission LLD's.

g RESULTS AND DISCUSSION A sample collection summary for 1986 is included in Table 6. 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. Disagreements in the comparison of WI DHSS and LACBWR reported results from the environmental split sample monitoring program are listed in Table 7. Results from the individual sample analyses are listed in Tables 9-23.

Radioactive fallout resulting from the Soviet accident at Chernobyl was detected in WI DHSS and LACBWR samples collected during the time period of 05/01/86 - 07/01/86. Sample analysis results are discussed in the individual sections and dose calculations are performed in the section Dose to Individuals from Radioactive Fallout from the Soviet Accident al Chernobyl.

Air Particulate WI DHSS and LACBWR maintain separate air sampling stations. The indicator site f or both WI DHSS and LACBWR is located at Lock & Dam

  1. 8, 0.7 miles N. The control site for WI DHSS is located at the state office building in La Crosse, 16 miles N and for LACBWR at the Dairyland Power office in La Crosse.

A summary of reported activities by WI DHSS and LACBWR f rom the air particulate samples is included in Table 6. Disagreements in the reported WI DHSS and LACBWR results are listed in Table 7. Results from the individual sample analyses are listed in Tables 9-12.

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

The WI DHSS and LACBWR yearly averages for gross beta activity f rom the air particulate filters are comparable and showed no significant differences between their respective indicator and control sites.

The elevated gross beta activities for the time period of 05/07/86 -

06/12/86 are due to radioactive f allout f rom the Soviet accident at Chernobyl. Elevated gross beta activities were detected by WI DHSS &

W and LACBWR and were present in both the indicator and the control sites. Elevated gross beta activities were also detected in air particulate samples from the three other WI DESS environmental .

monitoring areas.

A summary of reported gamma isotopic activities for WI DHSS and LACBWR f rom the monthly or quarterly air particulate filter composites is ,

included in Table 6. Disagreements in the reported WI DHSS and LACBWR results are listed in Table 7. Results f rom the individual sr.mple analyses are listed in Tables 13-14. 1 In the WI DHSS gamma isotopic analysis bery111um-7 (Be-7) was detected in all composites from both the indicator and 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.

LACBWR does not report naturally occurring radioisotopes and no comparison can be made f or the bery111um-7 (Be-7) reported by WI DHSS.

All of the reported radioisotopes by LACBWR for the monthly composites of January - April and July - December were at trace activity levels and all were less than the respective WI DHSS MDC.

At the observed lower levels of activity, the WI DHSS and LACBWR data are comparable in the gross beta and gamma isotopic analysis on the air particulate samples. Influence by the LACBWR 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 DESS and LACBWR samples for the time period of 05/07/86 - 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), cesium-137 (Cs-137) and iodine-131 (I-131). The indicated radioisotopes were detected in both the control and indicator composites and the activities from both sites are listed in Tables 13 and 14. The indicated radioisotopes were also detected in air particulate composites from the three other WI DHSS environmental monitoring areas within Wisconsin at approximately the same activities.

The radioisotopes detected in the LACBWR sample analysis for the time period of 04/28/86 - 06/30/86 were zirconium-95 (Zr-95), ruthenium-103 (Ru-103), ruthenium-106 (Ru-106), cesium-134 (Cs-134), cesium-137 (Cs- -

137), cerium-144 (Ce-144), iodine-131 (I-131), cobalt-60 (Co-60),

manganese-54 (Mn-54) and barium-140 (Ba-140). The LACBWR detected activities for zirconium-95 (Zr-95), ruthenium-106 (Ru-106), cerium-144 (Ce-144), cobalt-60 (Co-60), manganese-54 (Mn-54) and barium-140 (Ba-140) were less than the respective WI DHSS MDC.

indicator and the control stations for WI DHSS and LACBWR. Elevated l

air iodine (I-131) activity was also observed in the three other WI ,

l DHSS environmental monitoring areas.

!O Surface Water The surface water samples are split samples taken as a grab sample on

a monthly basis. The discharge channel is taken as the indicator site and Lock and Dam #6 is taken as the control site.

A summary of reported activities by WI DHSS and LACBWR from the

  • monthly surface water samples is included in Table 6. Disagreements in the reported WI DHSS and LACBWR results are listed in Table 7.

Results from the individual sample analyses are listed in Tables 15-

18.

The WI DHSS and LACBWR reported activities f rom the monthly surf ace water samples taken at the control station, Lock & Dam #8, are all at background levels. All reported activities by WI DHSS for gamma

! isotopic and tritium were less than the respective WI DHSS minimum detectable concentration (MDC). All reported gamma-isotopic activities by LACBWR are less than the respective WI DHSS MDC.

Analysis of the surface water samples taken from the indicator site, discharge channel, by WI DHSS detected small activities of cobalt-60 (Co-60) and tritium (H-3). LACBWR analysis detected small activities

of manganese-54 (Mn-54), cobalt-60 (Co-60), cesium-137 (Cs-137),

barium-140 (Ba-140), cerium-141 (Ce-141) and tritium (H-3). Reported activities above the WI DESS MDC or the LACBWR MDA levels were lO i

comparable except f or the disagreements listed in Table 7.

! 9 l

I

All activities reported by either WI DHSS or LACBWR are below the standards for uncontrolled areas as specified in ICRP Report No.2 or 10 CFR 20. h Disagreements in the WI DHSS and LACBWR reported results are listed in Table 7. The WI DHSS and LACBWR sample analysis reports were reviewed ,

for possible problems in the sample analysis but no problems were noted. In general the disagreements were small and the reported activities involved were also small, at or only slightly above the required NRC LLD's. Dif ficulties in the tritium (H-3) analysis were resolved early in 1986 and only in January and February were disagreements noted.

Fish Both LACBWR and WI DHSS analyze the same samples with LACBWR first performing its analysis and then WI DESS.

A summary of reported activities by WI DHSS and LACBWR from fish samples is included in Table 6. Disagreements in the reported WI DHSS and LACBWR results are listed in Table 7. Results from the individual sample analyses are listed in Tables 19-20.

From the WI DHSS gamma isotopic analysis potassium-40 (K-40) was detected in all samples and cobalt-60 (Co-60) in two of the samples.

Cobalt-60 (Co-60) was also detected in previous years but is not detectable in all collected samples.

Reported O

LACBWR does not report naturally occurring radioisotopes.

activities f or LACBWR are manganese-54 (Mn-54), cobalt-60 (Co-60),

zinc-65 (Zn-65) and cesium-137 (Cs-137). The reported LACBWR activities f or manganese-54 (Mn-54), zinc-6 5 (Zn-65) and cesium-13 7 (Cs-137) were all less than the respective WI DHSS MDC.

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

Bottom Sediments Both WI DHSS and LACBWR analyze the same samples with LACBWR first performing its analysis and then WI DHSS.

A summary of reported activities by WI DHSS and LACBWR f rom bottom sediment samples is included in Table 6. Disagreements in the reported WI DHSS and LACBWR results are listed in Table 7. Results from the individual sample analyses are listed in Table 21. ,

The gamma isotopic analysis of the upstream sample, Lock & Dam #8, by WI DHSS detected cesium-137 (Cs-137) in one of the two samples, naturally occurring potassium-40 (K-40) and naturally occurring radioisotopes f rom uranium and thorium decay series in both of the samples. Analysis by LACBWR detected only trace activities of cesium-The detected activity by LACBWR 137 (Cs-137) and niobium-95 (Nb-95).

10

f or niobium-95 (Nb-95) was less than the respective WI DHSS MDC or the G required NRC LLD. The disagreement in the cesium-137 (Cs-137) for the b 09/23/86 sample was small. All reported activities by WI DHSS or LACBWR for the upstream site were less than the required NRC LLD's.

  • The highest activities f or both WI DHSS and LACBWR were detected at the discharge point with cobalt-60 (Co-60) and cesium-137 (Cs-137) predominating and smaller detected activities for cesium-134 (Cs-134)

. and manganese-54 (Mn-54). Inspection of the WI DHSS data from the discharge point f or 1984-19 86 shows a decreasing range of activity for cobalt-60 (Co-60) and cesium-137 (Cs-137) and this range is listed in Table 2. The observed decreasing range in activity would tend to indicate that the discharge point is not the best site to observe trends of accumulated radioactivity versus time. From correspondence with Dairyland Power Cooperatf.ve environmental department personnel, their observations are that 1.ne discharge point has a very small area to collect bottom sediment with larger aggregate predominating and that it also has a high scouring rate. The discharge site, however, is probably the only point available in the imediate area due to the large amount of riprap in the area.

From the downstream site, boat launch, WI DHSS detected activities above MDC values for naturally occurring potassium-40 (K-40) and naturally occurring radioisotopes from uranium and thorium decay series. LACBWR reported small activities for barium-140 (Ba-140) and cerium-144 (Ce-244) which are less than the respective WI DHSS MDC or NRC LLD.

b The reported activities by WI DHSS and LACBWR are comparable for all three sites.

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

Milk The milk samples are obtained as grab samples on a monthly basis and are then split for analysis.

A summary of reported activities by WI DHSS and LACBWR from milk samples is included in Table 6. Disagreements in the reported WI DHSS and LACBWR results are listed in Table 7. Results f rom the individual sample analyses are listed in Table 22. .

WI DHSS detected naturally occurring potassium-40 (K-40) in all samples and iodine-131 (I-131) in the 06/10/86 sample in its gamma isotopic analysis of the milk samples. AllThe other activities for 06/10/86 detected iodine-131 were below its MDC of 0.40 pCi/1.

activity for iodine-131 (I-131) was due to the radioactive f allout from the Soviet accident at Chernobyl. Iodine-131 (I-131) activities were also detected in milk samples from the three other WI DHSS environmental monitoring areas.

LACBWR does not report naturally occurring radioisotopes and a comparison is not possible with the WI DHSS data. The LACBWR reported activity for iodine-131 (I-131) for the 06/10/86 sample was in All other reported agreement with the reported WI DHSS result.

isotopes were less than the respective WI DHSS MDC's except for those differences listed in Table 7.

The WI DHSS and LACBWR sample analysis reports were reviewed regarding the disagreements listed in Table 7. No problems were noted in either g the WI DHSS or LACBWR sample analysis.

The reported data by WI DHSS f or 1986 is comparable to data reported for previous years. Influence by the LACBWR facility is not apparent in the milk samples analyzed by either WI DHSS or LACBWR.

WI DHSS detected only naturally occurring potassium-40 (K-40) above its MDC in its gamma isotopic analysis of the f ood product sample.

Activities f or iodine-131 (I-131) were be low its MDC of 60 pC1/kg.

  • LACBWR does not report naturally occurring radioisotopes and no other radioisotopes were reported above the respective LACBWR MDA.

The WI DHSS and LACBWR results are comparable and influence by the LACBWR facility is not evident in food product samples.

Radioactive fallout from the Soviet accident at Chernobyl was not evident or detectable in the food product sample.

O(~g i 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 doses, of Evaluating listed in Compliance with 10 CFR Part 50, Appendix I".

Table 3, were calculated f or the maximum exposed individual f or WI DHSS samples with activities greater than MDC and background levels.

From Table 3 it is apparent that the most significant dose to a maximum exposed individual is at the outfall site. The outfall site, however, is not readily accessible for individual use for recreationa.'

purposes including either fishing or swimming. Doses resulting from gaseous and liquid effluent releases are in compliance with 10 CFR Part 50, Appendix I.

Dose to Individuals from Radioactive Fallout from the Soviet Accident al Chernobyl h

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 for ruthenium-103 (Ru-103), iodine-131 (I-131) and cesium-137 (Cs-137) in approximately the same proportions as those reported in air particulate composites. Analysis of vegetrtion samples collected in September and October from the four WI DHSS envircnmental 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 from six major ellk h

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 slightly above the WI DHSS MDC of 12 pCi/ liter.

Dose calculations 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 I". The Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix calculated doses represent the dose received during the indicated time period due to radioactive fallout from the Soviet accident at Chernobyl. The doses, listed in Table 5, were calculated for the 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 4.

It is important to note that the doses listed in Table 5 are ,

calculated doses for the exposure periods listed in Table 4 and only represent the dose received from exposure to radioactive fallout from the Soviet accident at Chernobyl. From the doses listed in Table 5 it is apparent that the dose to the thyroid is the most important. The thyroid dose is due mainly to the detected activity for iodine-131 (I-131).

14

i.

I 'The thyroid dose received f rom air iodine (I-131) is an inhalation

! dose and was calculated from continuous air sampling. The air iodine ,

(I-131) activity listed in Table 4 is the average activity from four weekly samples.

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

. Iodine-131 (I-131) for the listed exposure period in Table 4 was detected in milk samples f rom within Wisconsin at activity levels of

<MDC (0.4 pCi/11ter) to 45 pCi/ liter. One allk 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 4 is probably greater than the average activity detected during the indicated time period but was i used for calculation purposes as a worst case possibility.

The activities for iodine-131 (I-131) detected in milk samples is less than the U.S. Food & Drug Administration's (FDA) Preventative Protective Action Guides (PAG's) which would require public health officials to take action to prevent food stuffs from entering commerce 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 L nuclear fuel cycle, including nuclear power plant. The EPA

! restriction for annual exposure is 25 millirems to the whole body or i 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 the Wis. Adm.

Code section HSS 157.12 which have been taken from U.S. Nuclear Regulatory Commission 10 CFR 20. The exposure limit stated in HSS 157.12 is 500 millirem whole body in any one year.

1 The calculated doses from radioactive fallout from the Soviet accident l -

at Chernobyl listed in Table 5 are below current state and federal l-regulations and present little risk to the Wisconsin general public.

ATTACHMENT A - RADIO-ENVIRONMENTAL SAMPLE ANALYSES MAXIMUM LOWER LIMITS OF DETECTION VALUES (LLD)G - (Cont'd)

(a) Calculation of Lower Limits of Detection:

The LLD is the smallest concentration of radioactive material'in a sample th'at will be detected with 95%

probability with 5% probability of falsely concluding that a blank observation represents a "real" signal.

For a particular measurement system (which may include radiochemical separation):

4.66 ab

,r LLD = 4 E x V x 2.22 x Y x Exp(-AAt)

J s's WilERE: ~

LLD is the a priori lover limit of detection as. defined above (as picoeurie per uhit mass or volume).

sb is the standard deviation of the background counting rate or of'the coanting rate of a blank sample as appropriate (as counts per minute). Typical values of E, V, Y, and at shall be used in the calculations.

Z E is the counting efficiency (as counts per transformation).

  • V is the sample size (in units of mass or volume). =

w 2.22 is the number of transformations per minute per picoeurie.

O w

Y is the fraction radiochemical yield (when applicable).

L A is the radioactive decay constant for the particular radionuclide.

at is the elapsed time between sample collection (or end of the sample collection period) and time of c counting. o I
