摘　　要：设计研制了测量范围由环境级到核事故级的宽量程γ辐射探测器。设计采用双GM计数管，利用脉冲计数技术，使探测器的量程达到9个量级，从环境级到事故级，高压电源、前置放大器、放大器和信号处理器设计在探测器内，做成一通用型、智能化的宽量程探测器。利用辐射源室中的^60Co源，在测试室内产生剂量率规则变化的γ辐射场，在不同剂量的标准点上进行测试，剂量率的测量误差小于士10％，好于一般计数管探测器士30％的测量误差。Wide range γ radiation detector monitioring range from environment level to accident level was designed and made. Double GM tubes were used and pulse counting technique was utilized. The HV power, head amplifier, amplifier and signal processing system were integrated in the detector. So it was a universal and intelligent wide range detector. The detector was tested in regularization γ radiation field of ^60Co, and its performance was very good.
