Background
In the nuclear accident emergency handling exercise process, in order to meet the training requirements of actual combat, a real radiation source is often required to be used for constructing a nuclear accident radiation scene. However, the rays emitted by the real radioactive source have a certain harm to human bodies. Therefore, the use of real radioactive sources during nuclear accident emergency handling exercises should be reduced or avoided as much as possible, thereby avoiding irradiation injuries to emergency handling personnel. The radioactive source simulation equipment based on the nuclear pulse signal generator is adopted, so that the training requirement can be met to a certain extent. However, the simulation equipment has the defects of large volume, inconvenience in carrying, complex structural design, poor field adaptability and the like, and is difficult to meet the actual requirements of nuclear accident emergency treatment training.

Because the response conditions such as the instantaneous dose rate value or the buzzing alarm frequency of the nuclear radiation detector are directly related to the distance between the detector and the radioactive source, the response conditions of the detector are generally utilized to search and position the radioactive source in the actual searching process of the radioactive source. Thus, it should be realized that the response of the detector varies with the distance of the radiation source when training with an analog radiation source.
