Radiation Slide Rule for Atomic Fallout Problems
Abstract
A nuclear weapon explosion results in earth and bomb debris which has become contaminated with fission products, residual radiation or fallout. The problem of decontaminating an area depends largely on the radiation intensity and the rate of decay of the fission products. Previous methods of determining dose to personnel during decontamination operations used tables or graphs to determine the total dose which would be received at a certain location over a specified period of time. Except for values used in the tables the desired value must be obtained by interpolation. This report presents the theory, construction, and use of a circular slide rule which is designed to solve passive defense problems dealing with residual radiation. The rule Is based on the t (exp -1.2) law of radioactive decay. The slide rule can be used to solve an infinite number of individual problems without the necessity of interpolation in tables or construction of graphic plots. A number of typical problems are worked with the slide rule to indicate its method of use.
