摘　　要：这里介绍了一种新型伽玛辐射检测仪的研制和应用情况,并详细讨论了该仪器在研制中的特色电路。在探测器与操作台连接部分,使用一根同轴屏蔽线达到了电脉冲信号和核辐射探测器工作高压同时传送的目的。在电源电路中,设计了电池欠压保护电路,即当电池充电时,可以实时指示充电进行、充电完成等状态,并能够及时得到充电饱和保护。This paper introduces the study and application of a new type of γ-radioactivity detector. The features of the detector's circuit are discussed in detail. In the circuit of linking to explorer, there is only one transmission line used for transmitting electricity impulse and the high-voltage for explorer simultaneously. At the moment of saturation in charging, the apparatus can supply protection for super saturation. A protective circuit is also designed for excessively low battery voltage for long running time.
