鉴于放射源的使用在辐射监测系统定期试验中带来的辐射安全问题,需要对试验方案进行改进设计。本文通过对探测器输出信号特性及电子学线路对信号处理方法的研究,介绍一种利用电子学方法产生的信号代替探测器的输出信号,实现在无放射源操作的情况下完成定期试验的方法。 In view of the radiation safety issues associated with the use of radioactive sources in routine tests of radiation monitoring systems, improved design of test protocols is required. In this paper, the characteristics of the detector output signal and the electronic circuit on the signal processing methods, the introduction of a method using the signal generated by the electronics instead of the detector output signal to achieve the operation without radioactive sources in the case of regular completion of the test method .
