Description

technical field [0001] The invention relates to the technical field of radiation detectors, in particular to a gamma radiation detector. Background technique [0002] In the prior art, gamma radiation detectors cannot effectively measure gamma rays, so that the measurement accuracy is not high enough, which affects the later judgment process. [0003] Therefore, there is a technical problem that the detection accuracy of the gamma radiation detector is not high in the prior art. Contents of the invention [0004] The invention provides a gamma radiation detector, which solves the technical problem of low detection accuracy of the gamma radiation detector in the prior art. [0005] In order to solve the problems of the technologies described above, a technical solution adopted in the present invention is: [0006] A gamma radiation detector includes a crystal system, a gamma probe and a processing system, the gamma probe includes a gamma detection element, a photoconducto...
