Determining Important Nuclear Fragmentation Processes for Human Space ExplorationsSpace radiation from cosmic ray particles is a major risk for astronauts in long-term human space explorations such as a permanent moon base or a trip to Mars. Radiation shielding is needed to reduce the radiation hazard to astronauts, and models have been developed in order to evaluate the effectiveness of different shielding materials. In this talk we determine the nuclear fragmentation cross sections which will most affect the radiation risk behind typical radiation shielding materials. As a result, these cross sections need more theoretical studies and accurate experimental measurements in order for us to more precisely predict the radiation risk in human space explorations.
