摘要
利用60Co和137Csγ辐射源测定了塑料闪烁探测器的γ灵敏度,给出了ST401、ST1422和含6Li(4%)塑料闪烁探测器的测定结果,获得了1.25和0.66MeV的γ灵敏度随闪烁体厚度的变化关系,实验结果与理论计算值在测量不确定度内一致。
60Co and 137Cs γ radiation sources were used to measure theγ sensitivity of plastic scintillator detector. It was obtained that the sensitivity of 1.25MeV and 0.66MeV γray for ST401,ST1422,6Li(4%) plastic scintillator detector with different scintillator thickness. The experiment data accord with theoretical sensitivity in the range of measuring uncertainty.
