Response Functions of NaI(Tl) Detectors to Terrestrial gamma Radiation

摘要

Computer programs, serving for calculation of detector efficiency and energy deposition spectrum for scintillation crystals irradiated by isotropic or half-isotropic gamma-ray fields were elaborated. The Monte-Carlo models used in calculations are valid for gamma-ray energies <= 3.0 MeV (case of terrestrial gamma radiation). Results of computations for four different NaI(Tl) crystals are presented in form of tables and a comparison of a calculated spectrum of uranium, measured in exp 2 pi geometry by the 1.5'' x 2'' probe with experimental results is given.
