Analytical methods and computer programs were developed at Douglas for use in establishing the radiation shielding requirements of space vehicle systems. Current techniques for performing space radiation shielding analyses are reviewed in the context of the digital computer programs in which they have been incorporated. Calculations dealing with the transport of primary charged particles and secondary reaction products through matter are performed by the CHARGE program for geometrically simple systems. The calculation of radiation levels in geometrically complex vehicle-shield configurations is accomplished by the SIGMA program, using the QUAD generalized quadratic surface geometry package. Procedures for ascertaining the optimal distribution of shield mass subject to specific dose design criteria are presently under development.
