Abstract:

The primary objective of this project was to determine the military significance of fallout contamination from small yield fission weapons. The specific objectives were to 1 make the necessary measurements during Shot Fig to delineate the fallout gamma-radiation field produced by a land-surface detonation of a fission weapon 2 use data collected to construct a fallout model for use with any wind pattern, and evaluate extremes in militarily significant contamination intensities for the same yield ranges and 3 define the attendant plutonium contamination problem. A dynamic close-in fallout model is presented for yields of 1 to 100 tons, which accounts for growth and drift of the cloud during its rise and is consistent with Fig measurements of cloud shine and amount of activity deposited, together with dose-rate intensity as functions of downwind distance. Keywords Fallout Contamination Low Yield Bursts.
