十四期圆桌里面讨论的时候涉及到了辐射问题,这里把一些相关的东西放过来,以便有一个大概的认识。
宇宙线,太阳风,其它恒星风,来自行星的辐射(例如木星)
一个总结性的关于辐射危害的图片:http://www.space.com/21353-space-radiation-mars-mission-threat.html
行星磁场+行星大气 屏蔽层,例如金属壳,水舱等

十四期圆桌里面讨论的时候涉及到了辐射问题,这里把一些相关的东西放过来,以便有一个大概的认识。
辐射来源

辐射危害
一个总结性的关于辐射危害的图片:http://www.space.com/21353-space-radiation-mars-mission-threat.html
图片中说地球上的人每天平均接受到的辐射剂量为 10mSv(10^{-3}Sv,这个图片里面错了),根据美国 NRC 的数据,美国人平均每年接受的剂量是 6.2mSv,我怀疑上面 space.com 这张图上面的单位错了,这些辐射主要来源来自自然背景中的辐射(太空,地质,人体内)。其中美国人接受的背景的有害辐射中,空气中的氡是主要的来源。
