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.

The National Aeronautics and Space Administration (NASA) has developed spacecraft maximum allowable concentrations (SMACs) for contaminants that might be found in the atmosphere within spacecraft during space missions to ensure the health and well-being of astronauts traveling and working in this unique environment. In volume 1 of this series, NASA developed SMACs for 11 compounds: acetaldehyde, ammonia, carbon monoxide, formaldehyde, Freon 113, hydrogen, methane, methanol, octamethyltrisiloxane, trimethylsilanol, and vinyl chloride. Volume 2 includes SMACs for 12 more airborne contaminants: acrolein, benzene, carbon dioxide, 2-ethoxyethanol, hydrazine, indole, mercury, methylene chloride, methyl ethyl ketone, nitromethane, 2-propoanol, and toluene. In developing SMACs from the toxicological literature, NASA followed the Guidelines for Developing Spacecraft Maximum Allowable Concentrations for Space Station Contaminants published in 1992 by the National Research Council.
