Abstract
Radiation exposure estimates for female crew members within simple hemispherical habitats constructed of aluminum on the surface of Mars are made for representative radiation environments consisting of solar particle event protons. Females, because of their generally smaller physical stature, have less body self-shielding and are expected to receive larger doses than males for the same incident radiation environments. In this work we use the BRYNTRN radiation transport code, originally developed at NASA Langley Research Center, and the Computerized Anatomical Female human geometry model to estimate exposures for aluminum shield areal densities corresponding to those provided by a spacesuit, a surface lander, and a permanent habitat. Comparisons of the predicted organ exposures with current NASA Permissible Exposure Limits are presented and discussed.
