宇宙辐射是宇航员在空间飞行中,无法避免的问题之一,也是他们所遇到的最危险的一个问题。宇航员在低地球轨道会遇到各种不同形式的宇宙辐射,其强度都比在地球上要高50倍。美国航天飞机及俄罗斯的“和平号”空间站的全体人员所遭受的强烈辐射,包括中子、电磁辐射(X 射线和γ射线)和诸如其它元素的质子、原子核之类的各种带电粒子的辐射。也许带电粒子由于其独特的贯穿特性而最难以对付,但所有宇宙辐射都会在生物 Cosmic radiation is one of the problems that astronauts can not avoid in space flight. It is also the most dangerous problem that they encounter. Astronauts encounter various forms of cosmic radiation in low-Earth orbits that are 50 times more intense than on Earth. The intense radiation suffered by all personnel of the U.S. space shuttle and the Russian Mir space station includes neutrons, electromagnetic radiation (X-rays and gamma rays) and various charged particles such as protons and nuclei of other elements Radiation. Perhaps the most difficult to deal with charged particles because of its unique penetration characteristics, but all cosmic radiation will be in the creatures
