摘要

NaI （Tl）闪烁探测器用途广泛，广泛应用于辐射探测和测量研究领域。本文对4 × 4 NaI （Tl）闪烁探测器的效率和分辨率进行了基于参数（即校准和几何形状）的研究。用于能量校准研究的标准放射源对γ射线能量分别为660.37 keV、1175 keV、1333.99 keV和2502.77 keV的分辨率分别为8.1%、6.0%、5.5%和4.1%。NaI （Tl）探测器对上述能量的效率分别为3.51%、2.09%、0.67%和0.38%，且与探测器参数呈线性关系。

Standardization of gamma-ray spectrometry using the NaI (TI) scintillation detector

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.
