碲锌镉(CZT)半导体探测器具有较好的能量分辨率,可在常温下使用,而且探测效率高,体积小,可满足低、中能γ/X探测要求。半球形CZT探测器由于具有好的角响应,适合进行γ辐射场周围剂量当量的测量。一般探测器对低能区γ射线剂量的能量响应偏低,通过脉冲幅度积分法可从软件角度调整探测器在低能区的能量响应,实现γ射线能谱与剂量的同时测量。本文研究了CZT
Zinc-cadmium telluride (CZT) semiconductor detector with better energy resolution, can be used at room temperature, and detection efficiency, small size, to meet the low, medium energy γ / X detection requirements. The hemispherical CZT detector is suitable for the measurement of dose equivalent around the gamma radiation field due to its good angular response. In general, the energy response of γ-ray dose of low-energy region is generally low, and the energy response of the detector in the low-energy region can be adjusted from the point of view of software by pulse amplitude integration method to realize the simultaneous measurement of γ-ray energy spectrum and dose.
