Other AbstractTotal ionizing dose effects caused by space radiation environment will be hazards for satellite electronic devices, and radiation shielding with appropriate materials is needed. Different shielding schemes for electron have been simulated with Monte-Carlo method. Three different shielding options, i.e., pure aluminum, pure tantalum and double-layer structure constituted by these two materials, have been compared. The results indicated that, when the shielding thickness is large enough, composite shielding for electron is better than single material shielding. And through experiments using the ~(90)Sr-~(90)Y source for irradiation test, pure material shielding and composite shielding are compared. The results were consistent with those of the simulation. The research conclusions can provide valuable references to optimization design for radiation shielding.
