An Analysis of Interplanetary Space Radiation Exposure for Various Solar Cycles

摘要: The radiation dose received by crew members in interplanetary space is influenced the stage of solar cycle. Using recently developed models galactic cosmic (GCR) environment and energy-dependent transport code, we have calculated at 0 5 cm water depth; using a computerized anatomical man (CAM) model, skin, eye blood-forming organ (BFO) doses as function aluminum shielding for various minima maxima between 1954 1989. These results show that equivalent within about 15% mean (maxima). maximum variation minimum factor three. We extended these calculations 1976-1977 to five practical geometries: Apollo Command Module, least most heavily shielded locations U.S. shuttle mid-deck, center proposed Space Station Freedom cluster sleeping compartment Skylab. calculations, quality ICRP 60, average CAM BFO 0.46 Sv/year. Based on an approach takes fragmentation into account, estimate calculation uncertainty if neglected.
