1.0 INTRODU.CTION The following constitutes the current Monthly Progress Report for the Environ-mental Radiological Monitoring Program conducted at the Point Beach Nuclear Wisconsin.

Plantreport.

this Two Rivers, Miss ing- entries-indicate analyses that are not completed; theResults of 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 environraental media samples. None of ,

the media sampled during the current month contained radioactivity attribut- l able to the operation of Point Beach Nuclear Plant. '

For'all gama isotopic analyses, the. spectrum is computer scanned f rom 80 to 2048 KcV. Specifically included are Nn-54, Fe-59, Co-58 Co-60, 2n-65 Zr-Nb-95, Ru-103,_Ru-106. 1-131, Ba-La-140, Cs-134 Cs-137, Ce-141 and j Ce-144. Naturally occurring: gamma-emitters, such as K-40 and Ra. daughters, are frequently detected in soil and sediment samples. Specific isotopes listed are _ K-40. TI-208. Pb-212, Bi-214. Ra-226, and Ac-228. Data listed as

"<" are at the 4.66 sigma level; others are 2 sigma. Unless otherwise noted.

-the less than value-("<") is for Ru-103 and n.ay be higher or lower for other-radionuclides. Gangna-emitters not specifically required to be identified are to be reported in the category labeled "Other Gammas."

All concentrations ~, except gross- beta, are decay corrected to the' time of -

collection..

All samples were ' collected as scheduled except as noted in the " Listing of Missed Samples."

Data Reporting Conventions

-1.0. All activities,except gross alpha and gross beta, are decay corrected to collection time or the end of the collection period.

2.0. Single Measurements Each single measurement is reported as follows:

xis where x = value of the measurement; s = 20 counting uncertainty (corresponding to the 95% confidence lev el ) .

In cases where the activity is found to be below the lower limit of detection L it is reported as

<L where L = is the lower limit of detection based on 4.660 uncertainty for a background sample.

3.0. Ouplicate Analyses 3.1. Individual results: x1 t-si-x2 t sg Reported result: xts where x = (1/2) (x1 + x2) s = (1/2) s 2 , 3j 3.2. Individual results: <ll

<L2 Reported result: <L where L = lower of L1 and L2 3.3. Individual results: xts

<L Reported result: x i s if x > L; (L otherwise B-2

- 4.0. Computation of Averages 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 I and standard deviation (s) of a set of n numbers x1, x2+ An are defined as follows:

x = f Ix

$, I (x-I)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 valuer h the averaging group are less than the highest LLO,-the highest LLO is reported.

4.4 If all but one of the values are less than the highest-LLO, the single value x and associated two-sigma error is reported.

L 4.5. In rounding off, the following rules are followed:

L

4.5.1. 'If the figure following those- to.be retained is less than 5, the figure is dropped, ano the retained figures are kept unchanged. As an example,11.443-is rounded off to 11.44.

L 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 an 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 dropped, and the last-place figure retained is increased by one if it is an odd number or it-is kept unchanged if an even nunber.- As an example,11.435 is rounded off to 11.44, while 11.425 is rounded off to 11.42.

N Appendix A Interlaboratory Comparison Program Results r

Teledyne Isotopes Midwest Laboratory (fomerly Hazleton Environmental Sciences).

has participated in interlaboratory comparison (crosscheck) programs since the-fomulation 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 Iaboratories. The pu provide an independent check on the laboratory,rpose s; analytical of such a program procedures and to is 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.EResults consistently higher or lower than the known values or outside -

the- control limits indicate a need to check the instruments or procedures

-used.

The results in Table A-1 were: obtained through participation in the environ-mentalL sample crosscheck program for milk,. water, air filters,:and food samples during ;the period January 1986 through December,1990. - This program has been conducted -by the U.S. Environmental Protection Agency. Intercomparison and Cali.bration :Section.--Quality Assurance Branch, Environmental Monitoring and -

Support Laboratory, Las Vegas, Nevada.

The.results'in Table A-2 were obtained for thermoluminescent dosimeters (TLDs);

duringl the -period 1976,1977,1979,1980,1984, and 1985-1986 through-partici--

Data Retorting Conventions 1.0. All activities,except gross alpha and gross beta, are decay corrected to collection time or the end of the collection period.

2.0. Single Measurements l

Each single measurement is reported as follows: I Xis where x = value of the measurement; 5 = 20 counting uncertainty (corresponding to the 95% confidence level).

In cases where the activity is found to be below the lower limit of detection L it is reported as

<L where L = is the lower limit of detection based on 4.660 uncertainty for a background sample.

3.0. Duplicate Analyses 3.1. Individual results: x; t s}

ng t sg Reported result: xis where x = (1/2) (x1 + x2) sa (1/2) sf+sf 3.2. Individual results: <L1 (Lg Reported result: <L where L = lower of L1 and L2 3.3. Indivioual results: xis

<L Reported result: x i s if x > L; l <L otherwise l

4.0. _ Computation of Averages 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 deviation (s) of a set of n numbers x1, x2, . . . x n are defined as-follows: ,

x = kIx 3, I (x-x)2 n-1 4.2 Values below the highest lower limit of detection are not included in the average.

4.3 Iflall 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.following those to be 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 an 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 _2 eros begnd the five, the figure 5 is. dropped, 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_.44, while-11.425 is rounded off to 11.42._
