During mission all of the telecommunication and electronic components in satellites expose to ionizing radiation. This factor can cause damage to the structure and function of the satellite. This paper examines the different structures that make radiation shielding satellites in GEO orbit. In this work, the amount of ionizing radiation is calculated using the MCNPX code. The simulation results indicate the importance of each factor in designing shielding.
