GAMMA SPECTROSCOPY - OVERVIEW
www.nrc.govJun 01, 2011 · • The gain determines the range of gamma ray energies that are seen on the spectrum. Components of a Gamma Spectroscopy System Amplifier 31 For example, a particular gain might result in a spectrum viewing gamma rays of 20 to 2000 keV. If higher energy gamma rays must be seen, the gain is lowered.

The higher and lower Gaussian tails are a consequence of compton scattering within the patient. D. The result of additional scattered photons generated in the collimator. E. A consequence of patient motion during scanning.
