WebCaesium-137 is one such radionuclide. It has a half-life of 30 years, and decays by beta decay without gamma ray emission to a metastable state of barium-137 (137m Ba). Barium-137m has a half-life of a 2.6 minutes and is responsible for all of the gamma ray emission in this decay sequence. The ground state of barium-137 is stable. Webextracted from the resin by this eluting solution. The cesium atoms have a half-life of 30 years and is always decaying and building up an equilibrium amount of Ba-137m. Ba-137m has a half-life of only 2.55 minutes (153 seconds) and quickly decays down to its stable ground state by the emission of a 0.662 MeV gamma ray. Ba Ba Cs 56 55 137m 137 ...
