Based on Time - to - Count technology , a environmental Gamma - ray radicalization monitor is devel- oped using G - M tube and Single - chip microcontroller（MCU）. The Time Measuring is realized by using digital electric circuit and MCU, Impurities Time is overcame , time resolution is raised effectively and the appli- cation life of G - M tube is extended greatly. The environmental Gamma - ray radicalization monitor can be used in the hospitals , public places , and the relevant departments of nuclear industry ...
