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. WebApr 6, 2024 · To calibrate the channel vs energy, the experimentalists use a gamma source which has known energies (Eu-152, Co-60, Na-22, 133-Ba, 137-Cs) and matches the histogram centroids (channels of known energy peaks) with the known energies using least-squares fit to either a straight line or a quadratic.
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 spectrum for 137 Cs shows that if the gamma ray scatters and escapes the crystal then the energy deposited will be less than the full-energy peak (see Figure 1-3). The actual energy deposited depends upon the angle of scatter as described in the equations above. The spectrum shows that many pulses have energies in a range below the Compton ...
