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. [4] The energies of both the beta decay of cesium-137 and the subsequent gamma decay of the excited barium 137 are 512 keV and 662 keV, respectively. [4]

Both the electron and gamma emissions are highly ionizing radiation . The gamma radiation is very penetrating, and the beta radiation, though very short range, is very dangerous when ingested because it deposits all that energy in a very short distance in tissue. Caesium-134 is not produced via beta decay of other fission product nuclides of mass 134 since beta decay stops at stable 134 Xe. It is also not produced by nuclear weapons because 133 Cs is created by beta decay of original fission products only long after the nuclear explosion is over. 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. [4] The energies of both the beta decay of cesium-137 and the subsequent gamma decay of the excited barium 137 are 512 keV and 662 keV, respectively. [4] This is a supplemental video I am doing for a case presentation regarding the class (Bio statistics & Epidemiology) I am taking over the summer of 2013. For emergency assistance, call 911 For EH&S emergencies, including after hours, call (650) 725-9999 beta decay of caesium-137.

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. The time required for a radioactive substance to lose 50 percent of its radioactivity by decay is known as the half-life. Cesium-137 In the case of caesium-137, conversion electrons carries on average 5% of the decay energy.
