| 摘 要： | 使用新型YAP：Ce无机晶体配大线性电流光电倍增管组成闪烁探测系统，采用散射法将60Co源（约2.2×1014 Bq）散射为单能γ射线，实验测量探测器系统的γ射线灵敏度，并结合计算机数值模拟计算对数据进行分析处理。新型YAP：Ce无机晶体对γ射线的灵敏度相对较高，是同体积CeF3晶体的10倍多。采用YAP：Ce无机晶体比CeF3晶体更有利于γ射线测量。

| Abstract: | The γ-rays from 60Co radioactive source(about 2.2×1014 Bq) are transferred into a series of single-energy γ-rays by a Cu scattering target. With these single-energy γ-rays the sensitivitiy of YAP: Ce scintillator detector was studied. The results indicate that the γ-ray sensitivity of YAP: Ce scintillator is more than 10 times of that of CeF3 scintillator with the same volume, and YAP: Ce scintillator could be regarded as an alternative solution for γ-ray detecting. |

| Keywords: | YAP: Ce inorganic scintillator γ-ray sensitivity Compton scattering |
