Computer Aided Radiation Analysis for Manned Spacecraft 911353

An innovative radiation assessment system combining computer aided design (CAD) capabilities with established NASA transport codes has been developed, permitting fast, accurate analysis capable of supporting preliminary design programs. Followed by brief discussions of the primary natural particle radiation sources and the operational sensitivities imposed by them on crew and spacecraft, the analytical system and methods are described. The use of this automated analytical tool called Brem (Boeing radiation exposure model), is then addressed regarding spacecraft design and the optimization of radiation shielding.
