The William Geagley Collection on Nuclear Safety contains government publications, memoranda, and pamphlets about counteracting nuclear contamination of food supplies from 1951 to 1960. The materials primarily document Geagley’s oversight of the development of food safety contingency plans for the Michigan Department of Agriculture. The materials also contain information relating to the Nevada Test Site’s plans for Operation Plumbbob, atmospheric and underground nuclear tests held in 1957 in Nevada.
