As noted above, cesium-137 decays to a short lived decay product, barium-137m. The latter isotope emits gamma radiation of moderate energy, which further decays to a stable form of barium. Cesium-137 is significant because of its prevalence, particularly dangerous fission product. Cesium-137 undergoes high-energy beta decay, primarily to an excited nuclear isomer of Barium 137, which in turn undergoes gamma decay with a half-life of about 150 seconds.

2009-03-16 · Cesium 137 is a beta negative emitter. In other words, it undergoes a beta-decay. When that happens, one of its neutrons changes to a proton, causing its atomic number to increase by one, and its atomic mass to remain the same.

Radioisotopes Radioactive Decay Ionizing Radiation

Cesium-137 decays in the environment by emitting beta particles. As noted above, cesium-137 decays to a short lived decay product, barium-137m. The latter isotope emits gamma radiation of moderate energy, which further decays to a stable form of barium. Cesium-137 is significant because of its prevalence, The characteristic 662 keV peak does not originate directly from 137 Cs, but from the decay of 137m Ba to its stable state. Caesium-137 has a half-life of about 30.17 years. About 94.6% decays by beta emission to a metastable nuclear isomer of barium: barium-137m (137m Ba, Ba-137m). Cesium-137 has a radioactive half-life of about 30 years and decays by beta decay either to stable barium-137 or a meta-stable form of barium (barium-137m).
