SPACE PROTON DOSES AT POINTS WITHIN THE HUMAN BODY
Abstract
Distribution patterns of absorbed dose influence the radiation response of a mammalian system, because of differing radiosensitivities of different organ systems. In a man exposed to space radiations; e.g., an astronaut, body self shielding produces nonuniform dose distributions which depend upon external shielding configurations and the incident radiation parameters. Is paper are presented the doses at twelve specific points in the body of a seated man exposed to isotropic incident space protons, where the man is inside various thicknesses of external vehicle shielding. The body points, selected for their radiobiological interest, are in (or on) sternum, chest skin, femur, spinal column, eye, central gut, and a series at various lateral depths on the waist. The protons reaching these specific points from all directions traverse tissue thicknesses that were determined from scale drawings of a statistically standard man (75-percentile). The proton penetration, secondary radiation generation, and total dose delivered to each specific body point was calculated using an IBM (Fortran) computer code.
