摘　　要：在进行中子/γ粒子测量时,一般采用致电离辐射探测器进行测量。闪烁体作为致电离辐射探测器的重要组成部分,需对闪烁体的特性进行实验测量。本文总结了在СГС 67型三通道γ加速器和DPF中子源上进行的NaI(Tl)、CeF3、PbWO4晶体的灵敏度、时间响应等特性的标定实验,分析了实验现象,合理地处理数据,给出了实验结果。During the radiative measurements of n/γ particles,the detectors ioning radiation are generally used.As the main part of the detectors ioning radiation,it is necessary to measure the characteristics of the scintillation crystals.In this paper,it is gained that the relative sensitivity and time characteristic of NaI(Tl)、CeF_3、PbWO_4 crystals calibrated by the type CΓC-67 γ generator and the DPF neutron generator. The results of the experiments were analyzed and the experimental data were processed reasonably.
