Human exposure to galactic cosmic rays in spaceThe Langley Research Center GCR (galactic cosmic rays) code (HZETRN) and the computerized Anatomical Man (CAM) model are used to estimate astronaut exposures, from GCR particles, for missions beyond earth's magnetosphere. Conventional risk assessments in terms of total absorbed dose and dose equivalent are made for skin, ocular lens, and bone marrow. For each organ, evaluations are made of relative contributions from incident protons, iron nuclei, and their secondary reaction products.
