Summary:

This paper describes a new microcomputer-based program that evaluates the radiation shielding of spacecraft or Space Station modules. This program runs on a computer-aided design (CAD) system that constructs and manipulates models of spacecraft. It uses the graphical and geometrical functions of the CAD system to analyse the radiation shielding provided by spacecraft models. The program has the following new features:When combined with composition and density data, the results provide input to existing radiation analysis programs. The total radiation shielding in a spacecraft or Space Station model corresponds to a superposition of shielding for all of the layers comprising a model. The archived intersections help in detailed analyses of shielding distributions. The new program obtains average shielding thicknesses in each solid angle element. These average thicknesses represent shielding more accurately than shielding computations that use single rays to determine the thickness for each solid angle element. The program runs on microcomputer and CAD workstations, providing flexible and cost-effective evaluations of radiation shielding distributions
