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 1
Reactor Contairment Building are specified for the location 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, i
Levels of radiation were not found to be significantly above
) 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.

These are operated by agencies which supply environmental-type samples (e.g., programs milk or water) but not containing to participant concentrations laboratories. ofThe radionuclides known to the issuing agency purpose of such a program is to provide alert it toan anyindependent check on the laboratory's analytical procedures and to possible problems.
