Radiation shields and methods of making the same

摘要

Various non-limiting embodiments disclosed herein generally relate to metallurgically dense radiation shields (10,20,30,40) formed from bismuth alloys comprising from 10 weight percent to 60 weight percent tin that are essentially free of toxic heavy metals chosen from lead, cadmium, and uranium; and radiation attenuation devices comprising the same. Other non-limiting embodiments disclosed herein relate to methods of making metallurgically dense radiation shields comprising bismuth alloys comprising from 10 weight percent to 60 weight percent tin. Still other non-limiting embodiments herein generally relate to methods of shielding radiation-emitting devices using metallurgically dense radiation shields formed from bismuth alloys comprising from 10 weight percent to 60 weight percent tin that are essentially free of toxic heavy metals chosen from lead, cadmium, and uranium.
