Web8 okt. 2024 · How is polonium used in everyday life? In commercial applications, polonium is occasionally used to remove static electricity in machinery or dust from photographic film. … WebWhat is polonium used for? Polonium is an alpha-emitter, and is used as an alpha-particle source in the form of a thin film on a stainless steel disc. These are used in antistatic devices and for research purposes. A single gram of polonium will reach a temperature of 500°C as a result of the alpha radiation emitted.
