THE OPTIMIZATION ANALYSIS OF THE MULTI-LAYER MATERIALS FOR SPACE RADIATION SHIELDING

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.
