Abstract: In recent decades, 2D materials have garnered significant interest for electronic and optical applications, particularly in the aerospace sector. Understanding the potential damage to electronic devices and sensors based on 2D materials is crucial, especially given the critical need for effective yet lightweight radiation shielding to maintain the health of satellite sensors. This study simulates the effects of cosmic radiation on 2D materials, focusing on damage mechanisms like displacements and sputtering. We employ the Geant4 simulation toolkit to analyze the energy spectrum of gamma, proton, and electron radiation passing through shields of various thicknesses, then estimate the consequent damage levels on the 2D material. Following the radiation exposure simulations, we use Density Functional Theory (DFT) calculations to evaluate any changes in the electronic and optical properties of the 2D materials. The goal of this research is to provide a comprehensive understanding of how shield thickness and weight impact the integrity of 2D materials under cosmic radiation exposure. This understanding is vital for guiding the development of more effective and lightweight shielding solutions, a crucial factor for electronic devices in satellites where every gram of weight counts
