Phosphorus-32 (P-32) is used in nuclear medicine as therapeutic
agent in the treatment of several diseases. P-32 has a half life of
14.3 days and decays directly to its ground state by emitting a
beta-minus particle. The decay table for P-32 is given. There are
no excited energy states or other radiation emitted during this
decay; therefore, P-32 is referred to as a "pure beta emitter.
