Kegunaan isotop polonium
- 210Po (with a half-life of 138 days) is used as static eliminator to remove static electricity in machinery. This is useful in machinery that produces electricity easily, for example, via rolling paper, manufacturing sheet plastics, and spinning synthetic fibers, which all readily produce static,. 210Po can also make use of its static eliminating properties when used in brushes that function to clean camera lenses and photographic films (Fig. IUPAC.84.1). 210Po has been used to manufacture atomic weapons. When combined with beryllium, polonium can act as a neutron-producing initiator. However, because of its short half-life, 210Po is no longer used in this manner.
