GAMMA RADIATION EXPOSURE
Abstract
The initial- and residual-gamma radiation exposures resulting from the surface detonation of megaton-yield-range thermonuclear devices were recorded in order to provide data for the determination and evaluation of the gamma-radiation hazards associated with such bursts. The following types of dosimeters were used as gamma radiation detectors: photographic, chemical, and Radiac Set AN/PDR-39. Instrument shelters were installed on reef, beach, and land locations to enable differentiation between initial- and residual-gamma exposures. Gamma-radiation exposure measurements were made at known distances from ground zero for each of five shots. The initial-gamma data has limitations; the bulk of the data was completely lost due to the destruction of most of the initial-gamma stations. A comparison of the fragmentary initial-exposure data with scaled data shows reasonable agreement, although there is an insufficient quantity of data to analyze for effective mean free paths.
