We are developing the computational dosimetry system used for cosmic-ray exposure, based on the Particle and Heavy Ion Transport code System PHITS. In the system, cosmic-ray environments outside spacecraft are estimated from the JAXA's space-radiation environment model, while cosmic-ray environments inside spacecraft are determined from the PHITS simulation. The details of the system will be presented at the meeting.
