WebPolonium-210 (Po-210) is a radioactive material that occurs naturally and at very low levels in the earth's crust and can be found throughout our environment. It is a product of the radioactive decay of natural uranium (U-238). Po-210 emits alpha radiation. WebProduction Astatine is formed by bombarding bismuth isotopes with alpha-particles. The resulting astatine is short-lived, with a half-life of just over 7 hours and hence it is necessary to prevent it from being evaporated by cooling the bismuth target during irradiation. 20983Bi + 42He → 11185At + 2 10n
