The use of suitable shielding materials can protect astronauts and electronic equipment from the hazardous effects of space radiation. In the present work, metal–organic frameworks (MOFs) and metal hydrides (MHs) materials are proposed with hydrogen loading to attenuate and reduce the effect of space radiation. The dose equivalent and fluence are simulated using High Charge and Energy TRaNsport (HZETRN) 2015 code with the 2010 solar minimum galactic cosmic ray (GCR) radiation environment. This analysis demonstrates that MOF and MH shielding materials exhibit a significantly improvement in shielding effectiveness after gradual increase in hydrogen concentration. It is also observed that C48H85Sc3NO15, B4O32C56H220, Be18O54H144C72 MOF, and MgFe5H48 MH shielding materials can improve the shielding efficiency more than polyethylene. The fluence analysis reveals that B4O32C56H220 MOF and LaNi5H24 MH materials significantly reduce secondary neutron production. In addition, the dose equivalent is compared between a deterministic code, the latest version of HZETRN 2020, and a Monte Carlo-based Particle and Heavy Ion Transport Code System (PHITS) transport code. For the first time, the PHITS code was used to simulate the advanced material configuration, and the results are compared with those obtained from the latest version of the HZETRN 2020 code.
