Research Progress on Space Radiation Biology

摘要: 空间电离辐射尤其是高能带电粒子辐射可造成生物机体的严重损伤， 是载人航天飞行的关键性限制因素之一。 研究表明， 带电粒子的生物学效应与其性质、 剂量以及不同生物学终点有关； 此外， 微重力环境可能会影响空间辐射生物学效应。 从多年来的空间搭载实验研究和地基模拟实验研究两个方面， 综述了空间辐射的生物损伤效应及其与微重力环境复合作用的生物效应。Space radiation, particularly induced by the highenergy charged particles, may cause serious injury on living organisms. So it is one critical restriction factor in Manned Spaceflight. Studies have shown that the biological effects of charged particles were associated with their quality, the dose and the different biological end points. In addition, the microgravity conditions may affect the biological effects of space radiation. In this paper we give a review on the biological damage effects of space radiation and the combined biological effects of the space radiation coupled with the microgravity from the results of space flight and ground simulation experiments.
