GAMMA RADIATION FIELD ABOVE FALLOUT CONTAMINATED GROUND,
NAVAL RADIOLOGICAL DEFENSE LAB SAN FRANCISCO CA
One of the objectives of Project 2.3, Operation Teapot, was to find the relationship between fallout gamma-radiation-source spectra which can be measured in the laboratory and the physical characteristics of the radiation field existing over a uniformly contaminated area. It was concluded that the direct, unscattered radiation field, which contributes about 80 percent of the roentgen effectiveness, could be computed from the source strength and spectrum on the basis of simple theory requiring knowledge only of the thickness of overlying inert material.
