These are operated by agencies which supply environmental-type samples (e.g., programs water) containing concentrations of radionuclides known to the issuing agency milk or but not to participant laboratories.
The purpose of such provide an independent check on the laboratory's analytical procedures and to a program 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.
Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used.

5.9.4.b Radiolooical Environmental Operatina Report 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 in 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 (i.e., results above the highest lower limit of j

detection for the period).

(3)

The average, lowest, and highest results.

In addition, the distance and direction relative to the Reactor Contairment Building are specified for the location 1

with the highest annual mean.

(b)

Elevated levels of I-131 were noted in fresh milk from May-July.

Elevated gross beta activity and I-131 were also noted in air particulates during May and June.

These ele-vated icvels were due to fallout from the Chernobyl Nuclear Plant (USSR) accident which occurred on April 26, 1986, Levels of radiation were not found to be significantly above i

)

local background at any other time at the sampling loca-tions. None of the media sampled contained radioactivity attributable to the operation of the Fort Calhoun Station.

(c)

See Appendix A.

I (d)

See Table 3.

i (e)

The limits of Technical Specification 2.1.3 were not exceed-ed by the primary coolant during the reporting period.

  • G8 = Gross beta; G5 = Gama scan.

D LLD = Lower limit of detection (based on 3 signa error for background sample unless otherwise indicated).

Mean and range are based on detectable measurements only (f.e., >LLD). Fraction of detectable measurements at specified locations is indicated in parentheses (F).

d L cad ons are spect M (1) by code, (2) by name, and (3) by distance and direction relative to Reactor Containment evilding.

e Non-routine results are those which exceed ten times the control station value. If no control station value is available, the result is considered non-routine if it exceeds ten times the typical pre-operational value for the medium or location.

f Results for sites not required by ihe technical specifications are excluded from this sumary.

Appendix A 1

Interlaboratory Comparison Program Results Teledyne Isotopes Midwest Laboratory (formerly Hazleton Environmental Scie has participated in interlaboratory comparison (crosscheck) programs since the formulation of its quality control program in December 1971.

These are operated by agencies which supply environmental-type samples (e.g., programs water) containing concentrations of radionuclides known to the issuing agency milk or but not to participant laboratories.

The purpose of such provide an independent check on the laboratory's analytical procedures and to a program 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.

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 sample crosscheck program for milk, water,in Table A-1 were nental samples during the period May 1984 through November 1986. air filters, and food been conducted by the U. S.
