Problems solved by technology
[0004] Currently, the crystal detector including the scintillation crystal is moved by using a fixed radiation source, but the crystal detector itself generally has a large number of wiring, including control lines, data transmission lines and power lines, etc. The range measurement will drive the wiring, and the frequent movement of the tooling will easily cause the wiring to break or even fall off, causing damage to the measuring tooling, inaccurate test data, etc.
And when the operator replaces the scintillation crystal on the crystal detector, the actual radiation source is idle, which increases the verification time of the crystal detector

The invention belongs to the technical field of material testing, and particularly relates to a crystal detector detection device. The crystal detector detection device comprises a substrate, at least two installation parts arranged on the substrate, a radioactive source detection mechanism and a moving mechanism driving the radioactive source detection mechanism to move, wherein the installation parts are used for placing a crystal detector to be detected, and the moving mechanism drives the radioactive source detection mechanism to move in the length direction of the substrate. The installation parts are arranged in the moving direction of the moving mechanism, the radioactive source detection mechanism is arranged over the installation parts, and the radioactive source detection mechanism sequentially passes through the upper portion of the installation parts and detects the crystal detectors installed on the installation parts. Therefore, according to the crystal detector detection device, the detection efficiency of the crystal detector is improved, and the radiation dose of operators is reduced.
Description
technical field [0001] The invention belongs to the technical field of material testing, in particular to a crystal detector detection device. Background technique [0002] Scintillation crystals can be used for the detection of x-rays, gamma rays, neutrons and other high-energy particles. The detection and imaging technology based on scintillation crystals has been used in nuclear medicine, high-energy physics, safety inspection, industrial non-destructive testing, space physics and nuclear prospecting, etc. has been widely applied. [0003] When scintillation crystals are used on a large scale, it is necessary to detect and calibrate their luminous light yield, and this process requires the use of radioactive sources. When the number of scintillation crystals to be verified is large, the frequency of use of the radioactive source is high and the time is long, so that the operator is exposed to radiation hazards when they live with the radioactive source for a long time. ...
