Abstract: Space is a hazardous frontier for exploration. As astronauts embark on missions to Low Earth Orbit (LEO) and beyond, the risk associated with radiation exposure increases as compared to the terrestrial background radiation experienced on Earth. To quantify the radiation risk for future exploration of the Moon and Mars, it is important to characterize how the space radiation field is modified by interaction with materials and the human body. Additionally, knowledge of how space radiation damage differs from typical terrestrial radiation damage from a biological perspective also informs our understanding of risk. This talk will focus on different components of modeling space radiation, including space radiation environments, radiation transport through materials, and multiple aspects of the risk of space radiation carcinogenesis.
