摘要
利用60Co和137Csγ放射源以及90Sr-90Yβ放射源对于几种常用闪烁探测器(溴化镧、碘化钠和塑料闪烁探测器)的信号特征、能量分辨率和时间分辨率等性质进行了测量,并对这些测量结果进行了对比分析。结果表明,塑料闪烁探测器适于进行时间信号的测量,碘化钠闪烁探测器适于进行能量测量;溴化镧闪烁探测器介于两者之间,既可以进行时间测量也可以进行能量测量,是一种新型的闪烁探测器。
To wholly recognize the characteristics of scintillator detectors, the signal characteristics, the energy resolution, the time resolution and the other properties of several common scintillator detectors （lanthanum bromide, sodium iodide and plastic scintillation detectors） are measured by using ^60Co and ^137Cs gamma sources as well as 90Sr-90Y beta source in this experiment, and the results are compared. It shows that the plastic scintillator detector is suitable for measuring time signal. Sodium iodide detector is suitable for energy measurement, lanthanum bromide detector which lies between the two detectors mentioned above, can be used for both time measurement and energy measurement. It is a new kind of scintillator detector and will be gradually used in the future scientific research.
