Space radiation biology

Abstract

Astronauts were constantly exposed to space radiation containing various kinds of energy with a low-dose rate during long-term stays in space. Therefore, it is important to judge correctly the biological effect of space radiation for human health. In addition, research for space radiation might give us useful information concerning birth and evolution of lives on the earth. Here, we described a view of the future about space experiments at an International Space Station. Therefore, we desire to educate the space researcher of the next generation for importance of research for space radiation.
