Radiation shielding materials, manufacturing processes, and equipment

Abstract

To provide alternative radiation shielding materials to lead, which has adverse environmental impacts, causes pollution, and has harmful effects on human health. [Solution] An alloy comprising bismuth, tin, and antimony is described. In embodiments, the alloy may substantially contain Sn = 3.4 to 9.8 atomic% (2.0 wt% to 6.0 wt%), Sb = 4.3 to 4.8 atomic% (2.6 wt% to 2.9 wt%), and Bi = 85.6 to 92.4 atomic% (91.2 wt% to 95.5 wt%). Indium can replace the tin component. The alloy can be used as a radiation shielding material. Methods for preparing and forming the alloy are described.
