Simulated radiation detection system

The invention provides a simulation radiation detection system. The system comprises a simulation radioactive source and a simulation detection device. The simulation radioactive source comprises a radio frequency tag and a shell, the radio frequency tag can generate a radio frequency signal under the action of an excitation signal generated by the simulation detection device, and the radio frequency signal comprises tag information of the radio frequency tag and a non-radiation physical signal; and the simulation detection device is used for receiving and identifying a radio frequency signal generated by the simulation radioactive source, and analyzing and processing the received radio frequency signal to obtain relative distance information and radioactive source parameter information of the simulation radioactive source. After label information and other non-nuclear radiation physical signals, received by the simulation detection device, of the simulation radioactive source are subjected to data analysis a
