Abstract : The Los Alamos Scientific Laboratory (LASL) is generating a Neutron-Gamma Monte Carlo (NGM) transport code that will produce a differential data map of the radiation environment created by a nuclear detonation. The output provides fluxes at a series of detectors surrounding the detonation, normalized to one neutron leaving the source in the given source-energy solid angle group. By appropriately weighting the output and integrating it with respect to the variables, the radiation field of given weapons can be theoretically predicted. A set of codes has been written at the US Army Nuclear Defense Laboratory (USANDL) to perform this flux integration over any of the desired variables (source energies and angles; detector energies, angles, and times), with weighting facility to handle specific situations. This report describes a digital computer program written for the GE-225 computer. The program integrates the LASL NGM radiation transport code differential flux output over the detector energy spectrum weighted by a specified function. (Author)
