A timing device of a radiation detection, measurement, identification and imaging system comprises high-energy photon detectors, a light pulse generator, and an optical fiber. Each high-energy photon detector comprises a scintillation crystal and a photoelectric conversion multiplying device. The high-energy photon detectors are respectively provided with a light hole. A light pulse signal is transmitted to the scintillation crystals through the light holes and then transmitted to the surfaces of the photoelectric conversion multiplying devices through the scintillation crystals, converted and multiplied by the photoelectric conversion multiplying devices, and read and processed by an electronic circuit. The mutually-independent high-energy photon detectors acquire absolute time from the light pulse signal generated by the light pulse generator, and timing and calibration are carried out between the mutually-independent high-energy photon detectors. According to the invention, the global clock is cancelled, timing is completed based on the time when the photoelectric conversion multiplying devices receive the light pulse signal, decoupling of the high-energy photon detectors is realized, the independence of the high-energy photon detectors is ensured, and the system can use or add/subtract the high-energy photon detectors more conveniently.
