英文摘要	The interplanetary radiation environment is detrimental to space missions, giving rise to cumulative damage to both astronauts and payloads and enhanced background levels in detectors. Therefore, there is a pressing need for a reliable simulation of these harmful effects for risk assessment and shielding optimization in manned space missions. We have modeled the interaction processes of the two most abundant galactic cosmic ray particle fluxes (protons and helium nuclei) using the Geant4 toolkit for a given space vehicle model. The total energy deposited due to protons and helium nuclei is calculated in this work, and the energy deposited due to the secondary particles generated by this radiation is also estimated.
