137 Cs gamma spectrum. 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. 1 Decay Scheme Cs-137 disintegrates by beta minus emission to the ground state of Ba-137 (5,6 %) and via the 661 keV isomeric level of Ba-137 (94,4 %) which has a half-life of 2,55 min.

Activity. (Ci/g). Decay. Cesium-137 is a radioactive element with a half-life of thirty years. Its decay results in the formation of Ba-137 with a very short half-life. Both elements have the Mar 20, 2012 Cesium-137 is an especially dangerous fission product because of its high yield during fission, moderate half-life, high-energy decay pathway, Cs-137 Radionuclide Fact Sheet · Related to these Topics · Relevant For These Roles · Program Areas · Roles · Topics · Quick Links.

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, relatively long half life (30 years), and its potential effects on human health.
