radioisotope. a radioactive form of an element, consisting of atoms with unstable nuclei, which undergo radioactive decay to stable forms, emitting characteristic alpha, beta, or gamma radiation. These may occur naturally, as in the cases of radium and uranium, or may be created artificially.
The radioisotope most widely used in medicine is technetium-99m, employed in some 80% of all nuclear medicine procedures â hence some 30 million per year, of which 6-7 million are in Europe, 15 million in North America, 6-8 million in Asia/Pacific (particularly Japan), and 0.5 million in other regions.
