SPACE RADIATION

摘要

The day of the International Space Station is drawing near. It will not be long before the cargo carried by the shuttle will include the pieces that will take shape as the International Space Station is constructed. When complete the number of crew members will swell the relatively small cohort that have spent months on Mir. Radiation will remain a concern, especially for those on missions with sojourns lasting many months.rnNot far behind is the engineers' need for more precise information about the radiation that must be taken into account in designing the shielding of the spacecraft destined for deep space missions. This means that equivalent doses in relevant tissues and the potential risks that such doses may pose must be estimated with considerable confidence.
