Abstract In radiation physics and dosimetry it is important to obtain an accurate analytical result for the measurements. This could be possible by controlling of some parameters of the experimental system. The detection efficiency is one of the most important parameter and it should be known in radiation measurements. In this study, the detection efficiency of a 3″ × 3″ NaI(Tl) scintillation detector has been simulated by FLUKA code for 6 different gamma ray energies at 1, 1.5, 2, 3, 5, 9, 15 cm source to detector distance. The simulated results were compared with the measurements done at 511, 662, 835, 1173, 1275, and 1332 keV gamma energies.

NaI(Tl) 检测器效率的 Monte Carlo 模拟

摘要 在辐射物理学和剂量学中，获得准确的测量分析结果非常重要。这可以通过控制实验系统的一些参数来实现。检测效率是最重要的参数之一，在辐射测量中应该知道。在这项研究中，3″ × 3″ NaI(Tl) 闪烁探测器的探测效率已经通过 FLUKA 代码模拟在 1、1.5、2、3、5、9、15 cm 源到探测器的 6 种不同伽马射线能量距离。将模拟结果与在 511、662、835、1173、1275 和 1332 keV 伽马能量下进行的测量进行比较。
