DESCRIPTION 
This series contains auto-radiographs of fallout collection 
plates of the Idaho National Engineering Laboratory gas stacks 
and soil samples. The series includes request forms from E.B. 
Tycz of the Environmental Safety Division for analysis by the 
Analytical Chemistry Branch of the Aerojet Nuclear Company, 
together with the plates of gas fallout from the stacks and 
deposition samples from the soil. Exposure time and date are 
marked on each plate as well as a tracking number generated by 
the Spectroscopy Section. The request forms indicate that the 
results were reported to D. Boyer and are in chronological 
order. The series also includes photographs of the radiographs. 
Isotopes include Rubidium-106, Sb-125, and Cs-137 soil samples. 
Titles of plates include "Stack Gas Filter" and "Fallout 
Plate." Plates from 1959 to 1974 have been destroyed; thus 
records documenting intentional releases as part of the Controlled 
Environmental Release Tests (CERT) 1963 through 1968 are not included.
