F 1.0 Introduction This report summarizes data obtained on sa=ples received through December, 1979 in the environcental radiological conitoring program for Grand Gulf Nuclear Station.
Where blank spaces appear following dates, work was not completed on these samples in time for inclusion in this report.
Data from analyses completed during the conth were within
! the expected ranges and do not indicate the presence of radio-activity from the operation of nuclear power stations.
The spectrum is computer scanned from -20 to -2000 Kev.
.Specifically included are Ce-144, 3a-La-140, Cs-134 Cs-137, Zr-Nb-95, co-58, co-60, Mn-54, Zn-65. Naturally occurring gamma emitters such as K-40 and Ra daughters are frequently detected but not listed here. Data listed as "<" are >at the 3a level, others are 2a. Unless otherwise noted, listed concentration is for Cs-137 and may be slightly more or less sensitive for other nuclides.
A summary of Quality Control data obtained during the month is presented in Section 3.0. Included in this section are data from all analytical programs, not only those associated with _
this program.
