多层材料空间辐射屏蔽优化分析

摘要

设计了4种多层屏蔽结构.利用基于GEANT4的MULYSSIS软件包,分别计算了4种典型轨道辐射环境中,几种屏蔽结构对电子、质子的屏蔽效果和对二者贡献的总剂量的屏蔽效果；计算结果表明,在不同轨道辐射环境下,存在最优的屏蔽结构方式.%Four different structures of multi-layer materials have been supposed. And the shielding effectiveness against of total ioning dose arousing of the electron and proton trapped in four different orbital environments, has been calculated and analyzed by using the MULYSSIS software which based on GEANT4 software package. It is shown that there is an optimization structure of multi-layer materials for different orbital radiation environments.
