摘　　要：G-M计数管广泛应用于特定区域的剂量率监测,具有结构简单、输出信号幅度大和高性价比、能适应恶劣的环境等优点。但在核设施环境监测、核事故监测等场所低能段时,存在过响应的现象。为了消除该影响,提高其灵敏度,本文采用在G-M计数管外层包裹金属锡,对计数管进行补偿,经比较分析,确定锡带的最佳宽度;并改进胶封固定的方式,从而在使用时更方便、性能稳定、且封装后的尺寸不会明显增大。G-M counter tube is widely used in-dose rate monitoring in specific areas.It has the advantages of simple structure,large output signal amplitude,high cost performance and adaptability to harsh environment.However,there has been a response phenomenon in the low-energy section of nuclear facility environmental monitoring and nuclear accident monitoring.In order to eliminate this effect and improve its sensitivity,tin is coated on the outer layer of G-M counter tube to compensate the counter tube.And improve the way of sealing fixing,so that it is more convenient to use,stable performance,and the size of the package will not increase significantly.
