摘要：
In this work we present a study devoted to the evaluation of the efficiency of a radiation shield, made out of the Nomex material doped with boron, in reducing the absorbed dose after bombardment with a 1 GeV proton beam. This study is relevant to the definition of optimal conditions for the shielding of astronauts from Solar Particle Events and Galactic Cosmic Radiation in space. Nomex shield is treated with boron at different concentrations. The production and transport of radiation produced after proton interaction is treated with a simulation tool based on Geant4. The added boron acts as an effective neutron mitigating material. The main preliminary result is that the average dose changes effectively despite the additional production of alpha particles from the reaction B-10(n, alpha).
