Preliminary study on radiation shielding properties of sulfur concrete on Mars

Abstract The hypothetical human exploration and inhabitation on Mars would certainly be difficult as the planet itself is vulnerable to outer space radiation. radiation consists of solar particle events (SPEs) that could easily penetrate very thin atmospheric layers Mars. Since sulfur concrete identified feasible in situ building material Mars, its shielding capability yet clarified. Here we report preliminary properties Martian composed elemental silica with latter incorporated by previous related studies upon irradiation gamma rays generated from Iridium-192. It found demonstrated an approximately 50% efficiency irradiation. a high potential well structural integrity post
