An Evaluation of Mass Integral Scaling as Applied to the Atmospheric Radiation Transport Problem
Abstract
This report presents the results of a comprehensive evaluation of mass integral scaling (MIS) as applied to the atmospheric radiation transport problem. MIS is an approximation used to predict the free-field radiation environments from atmospheric nuclear detonations. Codes like SMAUG and ATR use mass integral scaling of infinite homogeneous air transport data to generate environments which purport to reflect the near exponential vertical variation in density of air. The results are presented in the form of a series of mass range curves for a particular source spectrum and source/receiver altitude. These curves may be used to extract multiplicative MIS correction factors. A series of MIS isoerror contours, which clearly define the error bounds over various spatial domains, is also presented.
