Geant4 Simulations And Modeling For Space Radiation Environment
Abstract
The space radiation environment consisting of charged particles (electron and proton) and heavy ions gives a significant challenge to future space travels. Future space missions will rely more on accurate simulations of radiation transport in space through spacecraft to predict astronaut dose and energy deposition within spacecraft electronics. In order to accurately understand the space radiation environment, mostly Galactic Cosmic Radiations, Solar particle events and Trapped particles, fast simulations based on Monte Carlo methods are required. In this work, a systematic simulation study of modeling the space radiation environment is carried out. The radiation flux and radiation dose are measured using Geant4 simulations.
