WebCesium-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] Webthus exists more or less as a component in the radioactive cesium material. This component has a much higher gamma radiation emission per curie than Cs1S7, but a correspondingly much shorter half-life, about 2.3 years, and is therefore usually considered as a contamination in the radioactive ma- terial.
