太空是一個危險的地方，不僅因為那兒有流星，而且還有來自太陽和其它行星的射線。大氣層又一次充當了地球的保護層。從大氣層透進來的光線是地球植物所必需的，而這些植物則給我們提供了食物。同時，光線帶來的熱量使得我們的環(huán)境舒適，還有一些紫外線也穿透大氣層到達地球。宇宙中各種各樣的射線通過大氣層到達地球，然而，來自太陽的強烈輻射則被阻擋在外。一旦人類沒有大氣層的保護，就會受到這種輻射。但是人們穿上航天服或者呆在宇宙飛船里，則可以免受很多輻射的侵害。輻射是目前為止人類所知對太空探索者最大的威脅。放射線用“雷姆”作為衡量單位。地球上的所有輻射來自太陽、宇宙射線和放射性礦物質。我們每年所能承受的“正常輻射值”大約為200毫克，這只是一個大概的估計，因為這個值會隨著我們居住的環(huán)境而改變?？茖W家們認為，一個人能抵擋更多的輻射而不會受到任何傷寒，這個輻射值為60雷姆。
