Zusammenfassung:Radiation is an acknowledged primary concern for manned spaceflight and is a potentially limiting factor for interplanetary missions. Results from numerous space probes demonstrate heightened radiation levels compared to the Earth's surface and a change in the nature of the radiation field - particularly the presence of high energy heavy ions. To date less than 300 individuals have participated in the combined programs of the U.S. and CIS, with the vast majority of crew members ( similar to 250 persons) having flight exposures of less than 2 weeks. Very little is really known concerning the biological effects of human low level radiation exposure in space. Studies using lower life forms demonstrate a synergistic interaction between microgravity and radiation. More experiments are needed to confirm these findings, as are measures to counteract potentially harmful medical effects.
