GM tube radiation detector based on Time-to-Count method

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. (authors)
