Bismuth radiation
WebBismuth is without doubt a heavy metal; It occurs so low in the periodic table many were puzzled by the fact that it didn't seem radioactive. In fact its major isotope bismuth-219 was predicted to be so back in 1949. But it wasn't until 55 years later, when the French physicists finally observed its decay.

WebSep 8, 2024 · Radiation, Tumors, X-rays Abstract The level of tumor killing by bismuth nanoparticles (BiNPs) as radiosensitizers depends strongly on the powerful particle–matter interaction. However, this same radiation leads to the structural damage in BiNPs, consequently weakening their specific physicochemical properties for radiosensitization.
