WebThe Co 60 spectrum is 1.17 and 1.33 Mev, the Cs 137 is 0.66 Mev. In contrast, Cs 134 has 8 gamma components, which can be divided into three main groups: a high-energy, above 1 Mev; middle energy, about 0.8 Mev; and a low-energy, 0.6 Mev and below. Relative output of the three isotopes per curie is given in the third column of the table. 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.
