摘要

The NaI (Tl) scintillation detector is versatile and widely used in the field of radiation detection and measurement studies. In the present paper, a 4 × 4 NaI (Tl) scintillation detector’s efficiency and resolution are based on parameters viz., calibration, and geometries studied. The standard radioactive sources used for energy calibration studies found resolutions of 8.1%, 6.0%, 5.5%, and 4.1% for gamma-ray energies of 660.37 keV, 1175 keV, 1333.99 keV, and 2502.77 keV, respectively. The NaI (Tl) detector shows an efficiency of 3.51%, 2.09%, 0.67%, and 0.38%, respectively, for the above energies, which is in linearity with detector parameters.
