Abstract :In this study, the energy dependence of efficiency and resolution of NaI(Tl) detector were investigated using gamma ray spectrometry system. The full energy peak efficiency and energy resolution of NaI(Tl) detector were experimentally measured using 152 Eu, 137 Cs, and 60 Co radioactive sources at the energy range of 204 keV to 1408 keV. It was found that that the efficiency and resolution of NaI(Tl) detector decreases with the increasing gamma ray energy .
