Cs-137 gamma spectrum
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. The spectrum shows that many pulses have energies in a range below the Compton ... Web133Ba (Barium) There are 33 known isotopes of Barium, of which 133Ba is the most stable, it has a half life of 10.5 years, and emits a whole range of gammas, some which can be readily identified with a sodium iodide detector, and many that require higher resolution to see. This first spectrum is taken from a 133Ba sealed check source, using a ...

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. high school search peopleWebWe investigated H2O molecule adsorption that had an effect on the luminescence properties of the CsI(Na) crystal using experiments and first-principle calculations.
