2011-02-04 · original gamma ray energy minus 511 keV. If this happens often eno gh a single escape (SE) peak Photons Come Directly from Source Pair Production – Double and Single Escape Peaks 25 • If this happens often enough, a single escape (SE) peak appears on the spectrum. • The single escape peak is 511 keV below the photopeak energy. Se hela listan på epa.gov I registrated the gamma spectra of a 1 µCi Co 60, a 1 µCi Cs 137 and a 0.9 µCi Am 241 source, using an Alpha Spectra NaI (Tl) scintillator connected to an N Gamma Energy (KeV) Nuclide.
