Appropriate shielding design of spacecraft is essential in order to reduce the risk of space radiation exposure to a minimum. And also in making the future of manned planetary exploration will become more important. We evaluation of the optimal shielding materials and thickness in the spacecraft by PHITS simulation data and irradiation experiment data.
