WebJan 26, 2012 · The gamma counting efficiency depends on the detector size and source-detector geometry, but a 137 Cs counting efficiency on the order of 3% would be reasonable. The background on the GC may be higher than that of the LSC and this, combined with the lower efficiency, makes for lower sensitivity. With a 3% photopeak detection efficiency, … WebThe basic principle of operation involves the radiation reacting with a scintillator, which produces a series of flashes of varying intensity. The intensity of the flashes is proportional to the energy of the radiation, and this feature is very important. i promised i would tell by sonia weitzWeband gamma rays (γ). α particles are the least energetic, most massive of these decay products. An α particle contains two protons and two neutrons, and thus comprises a stable helium nucleus. α particles only weakly penetrate whatever matter they encounter.
