载人航天飞行空间辐射研究进展

Research Progress of Space Radiation for Manned Spaceflight

空间辐射是载人航天长期飞行及深空探测面临的最重要的环境因素之一。本文系统介绍了近地轨道飞行及载人登月、深空探测任务中空间辐射的时空分布特征,对当前空间辐射生物效应的研究热点(致癌、中枢神经系统影响、退行性变、辐射综合症)、空间辐射剂量测量、风险评估及防护技术的研究现状及进展进行综述,并提出了后续发展方向建议。

Space radiation is one of the most important environmental factors encountered in long term manned space flight and deep space exploration. The characteristics of spatial and temporal distribution of space radiation during low earth orbit flight,manned lunar-landing and deep space explore mission were introduced in this paper. Then the focused researches in space radiation biological effects（ cancer,central nervous system effects,retrogression and radiation syndrome）,dose measurement,risk estimation and protection technology of space radiation were reviewed systematically. Finally,the future development directions were suggested.
