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 ¹⁵²Eu,
¹³⁷Cs, and ⁶⁰Co 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.

Keywords
