| 摘 要： | 本文介绍了在我国返回式卫星舱内辐射剂量测量的一些结果,分析了轨道高度和舱体质量厚度对舱内剂量的影响。卫星舱内的复杂屏蔽引起各位置上的剂量有所不同,测量结果表明:最高和最低剂量点剂量水平之比在500km高度的轨道时为1.58,在300km高度的轨道时为1.23。本文还对近地空间的辐射危害及其防护问题进行了讨论。

| Abstract: | Several measured radiation doses on board our nation's recoverable satellites were presented. The effects of orbit altitude and shield mass thickness on dose were analysed. The complex shielding in the cabins of the satellites causes variations in the dose as a function of location. The measured results showed a dose maximum/dose minimum variation of 1. 58 at the - 500km, of 1.23 at the -300km. The radiation risk and protecticn during manned missions in low Earth orbit were discussed. |
