| 摘 要： | 空间生物学辐射效应是由空间辐射环境引起的，空间辐射环境的变化受太阳活动性影响。空间辐射水平比地表面水平高，航天员在空间所接受剂量比地面人员接受的吸收剂量高出100倍甚至更高，并且高能重离子的生物效应显著。文章简要阐述了空间辐射环境、空间辐射生物学效应与航天员的辐射剂量限值等问题。

| Abstract: | Variation of space environment is driven by solar activity.Space radiation will lead to biological effects of space radiation.Space radiation intensity is heavier than those on ground.Radiation dose absorbed by astronaut in space activites may be a factor of 100 or higher than those on earth,and biological effects of heavy ions must be considered.The paper briefly introduces space radiation environment,biological effects of space radiation and limited absorbed dose bound to Astronaut in space activity. |
