Cs-137 gamma spectrum
WebExample of a NaI spectrum is the gamma spectrum of the 137caesium isotope Cs shown in the figure aside. 137Cs emits a single gamma line of 662 keV. It should be noted that the 662 keV line shown is actually produced by 137mBa, the decay product of 137Cs, which is in secular equilibrium 137with Cs. WebThe process of identification of radioactive isotopes using gamma ray spectrum produced by scintillation detectors is a fundamental problem in physics. Military applications also require fast and efficient methods, especially in field conditions, for.

WebAug 28, 2015 · The energy spectra of gamma-rays emitted from mixed radioactive isotopes of Cs-137 and Co-60 with an almost identical radioactivity of 0.93 μCi were measured by using the FORS and the HPGe detector. In Figure 6 , the solid line (a) indicates that Co-60 was located in front of Cs-137, and vice versa for the dotted line (b). WebCobalt-60 (60Co) and caesium-137 ( 137 Cs) are the most widely used sources of gamma radiation. 60 Co produces gamma rays with energies of 1.173 and 1.332 MeV and has a half-life of 5.27 years, whereas 137 Cs produces gamma rays with an energy of 0.662 MeV and has a longer half-life of 30.1 years.
