The scintillation detector forms the main part of the instrument used, the electronic unit presenting the results produced. After a brief description of the process of gamma photon absorption in the material, the particular case of NaI(Tl), the scintillator used, is examined. The intensity of the scintillation caused by gamma -ray absorption and the characteristics of the photomuliiplier play a determining part in the energy resolution of the instrument. For the gamma recording spectrograph, we show to what extent the technique for using the electronic unit can modify the results. A detailed description is given of the activity measurement of a gamma -emitting radioelement by the spectrographic method. (auth)
