摘　　要：介绍了Time-to-Count测量方法 GM辐射探测系统设计。设计中,根据GM计数管Time-toCount方法测量辐射场强度的基本原理,完成了辐射探测系统设计,包括硬件设计和Time-to-Count方法的微控制器软件的编制。测试结果表明:Time-to-Count法较传统的脉冲法线性度更高,线性量程上限扩展了2个数量级。The design of a new type of GM Tube radiation detector was introduced. The detector was designed according to the principle of Time-to-Count method. The hardware structure and program flow design of the radiation detector were presented. The test results showed that the linearity of Time-to-Count method is better than pulse counting method. Besides,the range upper limit based on Time-to-Count method extended two orders of magnitudes compared with the traditional pulse counting method.
