po·lo·ni·um (Po),
(pō-lō'nē-ŭm),A radioactive element, atomic no. 84, isolated from pitchblende; the longest-lived isotope is 209Po (half-life 102 years); 210Po is radium F (half-life 138.38 days), the only readily accessible isotope.

polonium
A rare and highly radioactive chemical element (atomic number 84) discovered by Marie Curie, which has 33 distinct radioactive isotopes. It is an alpha particle emitter with a half-life of 138.4 days that decays directly to its stable daughter isotope, 206Pb, and has such a high energy of emission that it has been used to heat satellites and vehicles in outer space. 210Polonium is 250,000 times more toxic than hydrogen cyanide (HCN): the LD50 for an 80 kg person is 1µg of 210Po compared to 250 mg for HCN.Segen's Medical Dictionary. © 2012 Farlex, Inc.
