WebNov 24, 2008 · an alternative chemical form of cesium could prove to be a suitable replacement, and would be preferable to other nuclides (Cobalt-60) or technologies (x-ray), primarily because of the energy spectrum. However, there is no apparent economic incentive for private industry to develop alternative chemical forms of large (>20 curies) … WebJun 15, 2015 · The energy spectrum of I-131 was modeled as a superposition of the spectra of Cr-51 (320 keV) and Cs-137 (662 keV). Images were acquired with three adjacent 15% energy windows--photopeak(PP), upper scatter(US), and lower scatter(LS)--for small sources of these radionuclides. 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. diamond shaped emerald
