| 摘 要： | 我国在某航天任务中,将首次应用238Pu放射源.本文从该放射源所用的原料、放射源的结构、产生的射线种类以及包壳活化等方面分析了238Pu放射源在航天应用过程中的辐射特性.通过分析实验表明,距单个放射源1m处的中子辐射剂量率约为60 u Sv·h-1,在采取适当措施后,238Pu放射源将不会对人员和环境产生明显的辐射影响.

| Abstract: | The 238pu radioactive sources will be firstly applied to space mission in China. The materials used in the sources, the construction of the sources, radioactive species from the sources and neutron activation of the source＇ s cladding and etc are described in detail. The radiation protection for the sources is also discussed. Through the analysis results show that a single source＇ s neutron radiation dose rate is about 60 μSv·h-1 from 1 m. So after taking appropriate measures, the 238pu radioactive sources will not obvious effect on workers and the environment. |
