These peaks, labeled Full-Energy Peak, Single-Escape Peak, and Double-Escape Peak, will be separated by 0.511 MeV increments. Fig. 7.4 shows a typical spectrum that would be obtained for an incident gamma energy of 2.511 MeV. Gamma-ray spectroscopy is the quantitative study of the energy spectra of gamma-ray sources, such as in the nuclear industry, geochemical investigation, and astrophysics.. Most radioactive sources produce gamma rays, which are of various energies and intensities. When these emissions are detected and analyzed with a spectroscopy system, a gamma-ray energy spectrum can be produced.
