WebWe investigated H2O molecule adsorption that had an effect on the luminescence properties of the CsI(Na) crystal using experiments and first-principle calculations. We measured the emission spectra of the CsI(Na) crystal at different exposure times under gamma ray excitation. The experimental results showed that the energy resolution of the CsI(Na) … WebCobalt-60 (60Co) and caesium-137 (137 Cs) are the most widely used sources of gamma radiation. 60 Co produces gamma rays with energies of 1.173 and 1.332 MeV and has a …
WebCobalt-60 (60Co) and caesium-137 ( 137 Cs) are the most widely used sources of gamma radiation. 60 Co produces gamma rays with energies of 1.173 and 1.332 MeV and has a half-life of 5.27 years, whereas 137 Cs produces gamma rays with an energy of 0.662 MeV and has a longer half-life of 30.1 years. 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 ...
