  schema:description "A metal that fires off very powerful, very short-range radioactive particles as it decays through a chain of daughter atoms. Because the particles barely travel beyond the cell they hit, it can kill a cancer cell while leaving neighbouring healthy cells mostly untouched. Supply is scarce, so it is still mostly used in research studies."@en ;
