Astronaut Radiation Exposures at Selected Locations in the International Space Station 2001-01-2329

The bulk of the daily space radiation exposure to International Space Station astronauts will be received during times spent at selected locations. Using a recently updated and improved shielding model of the ISS, mass shielding distributions have been generated for these selected ISS locations. Anatomical math models have been developed for use in conjunction with spacecraft shielding models and space radiation dose codes to compute astronaut radiation exposures at the critical body organ level. In this paper we present a parametric study of crew radiation exposures at several selected locations, discuss the impact and effects on several mission scenarios, and present some ideas to further mitigate their exposures.
