Cs-137 gamma spectrum
Web241Am (Americium) Americium is a man made radioactive isotope, and is commonly found in smoke detectors. The source is an alpha emitter, and in the decay process it also kicks out a gamma at 59.6KeV. This is a typical gamma spectrum from Americium, as you can see, the tall peak at 59.6 KeV is very obvious and over powers everything else, it ...

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. grapevine chicken n pickleWebThe Cs-137 spectrum obtained after 50,000 counts using long and short filter shaping times of 10 µs and 7 µs, respectively, is shown Figure 4.
