Estimates of GCR radiation exposures on Mars for female crews in hemispherical habitats

Radiation exposure estimates for female crew members within simple hemispherical habitats constructed of aluminum on the surface of Mars are made for a representative radiation environment consisting of the current galactic cosmic ray environment. 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 environments. In this work we use the HZETRN radiation transport code, originally developed at NASA Langley Research Center, and the Computerized Anatomical Female human geometry model to carry out the study. Comparisons of the predicted organ exposures with current NASA Permissible Exposure Limits are presented.
