摘　　要：针对强辐射环境监测容易损坏仪器中电子元件的特点,提出基于宽量程探测技术的强辐射长距离探测方法。该方法将GM计数管置于被测环境中,并采用长电缆与外界电路相连。理论分析和实验结果表明,该方法利用宽量程探测技术能提高计数管的测量范围、延长使用寿命,同时还能避免后端电路受照射而损坏。因此,该方法能应用于强辐射环境的远距离监测。Aiming at the characteristics that the electronic components are easy damaged in strong radiation environment,a long distance detection method for strong radiation based on wide range detection technology is proposed.In this method,the GM counter is placed in the strong radiation environment,the measuring circuit is placed outside of the strong radiation environment, and a long cable is applied to connect the counter and the circuit.Theoretical analysis and experimental results show that it can improve the measuring range and service life of the counter, and can avoid the damage of circuit due to radiation.Therefore the method can be applied to the long distance monitoring in strong radiation environment.
