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.
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.
