Abstract

This article focuses on the simulation study of absorbed radiation dose rates in various polymers exposed to lunar cosmic radiation, using the SRIM (Stopping and Range of Ions in Matter) software. It evaluates the interaction of ions from hydrogen (H) to iron (Fe) with five polymers—polystyrene, Zylon, polytetrafluoroethylene (PTFE), Mylar, and polyvinyl chloride (PVC)—to assess their suitability for space applications. The results indicate that polystyrene exhibits the highest absorbed dose rates among the polymers studied, with dose rates increasing alongside ion mass and energy up to certain maxima. These findings contribute to understanding polymer degradation under space radiation and support the selection of materials for spacecraft shielding and equipment in environments lacking atmospheric protection, such as the lunar surface.
