Available in PDF, EPUB and Kindle. Book excerpt: The ramifications on shielding of manned space vehicles of the intense radiation environment in space was investigated. The radiation environment is reviewed and the problem of selecting shield materials in view of this environment is treated. The results of preliminary calculations to determine requirements for shielding against Van Allen radiation and solar protons are given. These results indicate that for most missions (outside the heart of the inner Van Allen belt) exposure to solar protons will be the controlling factor in determination of shield weight, suggesting the possible use of two crew compartments - one for normal operations and a smaller, heavily shielded one for short-term occupancy following solar flares.
