Spectrum
Typical spectrum from ISuS anti-Compton spectrometers (Compton suppression on/of) with unequalled highest suppression factor (97 at a 200 keV) starting from 2 MeV down to ~15 keV as an example for a multiple γ-transition radionuclide such as Br-82.
TIME IS MONEY!
Easy sample change by open and close the lead castle and annular crystal only.
