-1(a): .The number, of. sample locations, sample collection frequency and the number of samples collected this period?

for each class of sample is delineated in Table 1.

. A complete summary of the program findings is' presented i_n Table 2. For each type- of analysis of each sampled medium this-table considers separately all- indicator locations, all control locations and the-location with. the. highest

. annual'mean result. For each-of these classes, the table specifies the following:

(1) .The total number of analyses.:

(2) The: fraction of these' yielding detectable .results l(i.e.,. results above the highest lower limit of '

detection.for the period).

'(3) .The average, lowest,.and highest results.

i In addition, the distance and direction relative to the O Reactor Containment- Building are specified for the location with the highest annual mean, t . .

Table 3 'is.a listing of missed-samples.

(b) Results obtained show background levels of radioactivity

-in the environmental . samples. collected in 1988. The-residual'effect of previous nuclear tests was detected in one silt. sample (cesium-137). No station effect on the environment was indicate.

l Interlaboratory Comparison Program Results )

Teledyne Isotopes flidwest Laboratory (formerly Hazleton Environmental Scienc s) j has participated in interlaboratory comparison (crosscheck) programs since the i 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. l Results 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 environmental sample crosscheck program for. milk, water, air filters, and food samples during i the period liay 1984 through flovember,1988. This program has been conducted by l the U.S. Environmental Protection Agency Intercomparison and Calibration Section, Quality Assurance Branch, Environmental fionitoring and Support Laboratory, Las  ;

Vegas, llevada.

The results in Table A-2 were obtained for thermoluminescent dosimeters (TLD's) during the period 1976,1977,1979,1980,1984, and 1985-1986 through partici-pation in the Second, Third, Fourth, Fif th, Seventh, and Eighth International Intercomparison of Environmental Dosimeters under the sponsorships listed in Table A-2. .

Table A-3 lists results of the analyses on in-house spiked samples.

Table A-4 lists results of the analyses on in-house " blank" samples.

Attachment B lists acceptance criteria for " spiked" samples.

Addendum to Appendix A provides explanation for out of limit results.

57.0 4.3 60.3-77.7 Milk had high fat content which Sr-90 32.0!1.0 32.4-37.6 made analyses difficult. Ad-dition of errors to TIf1L result would ' put values within EPA control limits. EPA also had the same problem in analyzing its own sample.

I STW-511 Ra-228 8.1 1.4 4.6-8.0 TIf!L results are usually within EPA control limits. A.nalysis

of the next ' sample was within

} EPA control limits. flo further i- action is planned.

STW-516 Cr-51 80.3 17.5 61.3-78.7 Results in the past have been within EPA control limits and TIML will monitor the situation

in the future.

I- ST F-524 K 1010.7 158.5 1123.5-1336.5 Error in transferrance of data.

Correct data'was 1105 33.

Results in the past have been within the limits and TIML will monitor the situation in the future.

STW-532 I-131 9.0 2.0 6.2-8.3 Sample recounted after 12 days.

The average result was 8.811.7 (within EPA control limits).

The sample was recounted in order to check the decay.

Results in the past have been within the limits and TINL will continue to monitor the situ-ation in the future.

STU-534 Co-60 63.3 1.3 41.3-58.7 High level of Co-60 was due to contamination of beaker.

Beaker was discarded upon dis-

>- c ove ry of contamination and sample was recounted. Recount results were 53.213.6 and

1 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 l' Each single measurement is reported as follows:

xis where x .= value of the measurement; s = 2a 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: x1 i s1 xg t sg Reported r;sult: xis where x = (1/2) (x1 + x2) s = (1/2) s 2,3j 3.2. Individual results: <L1

<Lg Reported result: <L where L = lower of L1 and L2 3.3. Individual results: x s j

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

)

<L otherwise l

s B-2 l

- 4.0. Computation of Averages and Standard Deviations l .t 4.1- Averages and standard deviations listed in the tables are computed from all _ of th individual. measurements over the period averaged;.

for example, un annual standard deviation would not be the average of quarterly standard deviations. The average li and standard

~ deviation (s) of a set of n numbers x1, x2, . . . xn are defined.

as follows:

x= hex s= I(*~*)2 n-1 4.2 Values below the highest lower 1imit 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 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 zeros beyond the five, the figure 5 is dropped, and the last-place figure retained is increased by one if it is an odr'. number or it is kept unchanged if an even number. As an example,11.435 is l

rounded off to 11.44, while 11.425 is rounded off to 11.42. j i
