Nuclear radiation field imaging device based on CdZnTe array

Abstract

The invention discloses a nuclear radiation field imaging device based on a CdZnTe array, which comprises a CdZnTe detector, a rotary telescopic system and a processing system, wherein the processingsystem comprises a signal processing module, a nuclear radiation dose module, a mechanical control module and an imaging system; the mechanical control module controls the rotary telescopic system toenable the rotary telescopic system to perform rotation at a certain angle, and the detector can be telescopic in a certain distance; the CdZnTe detector is arranged on the rotary telescopic system for detecting nuclear radiation rays and converting the rays to charge signals; and the processing system is arranged on the rotary system for processing the output signals of the detector, and a nuclear radiation intensity distribution map for the radiation field is finally drawn. In the method of enabling the CdZnTe detector to be rotary and telescopic, the radiation dose values in different directions and positions in the radiation field can be detected, and according to the relationship between the nuclear radiation dose values and the directions and the positions, the radiation distributionmap for the radiation field can be displayed in the imaging system.

Description

technical field [0001] The invention relates to a nuclear radiation detection dose device, in particular to a cadmium zinc telluride nuclear radiation detection dose device, and a nuclear radiation field imaging device, which is applied in the technical field of nuclear radiation detection. Background technique [0002] Existing nuclear radiation dosimeters are mostly nuclear radiation dosimeters, which have the following deficiencies: [0003] Most of them use scintillator detectors, but the range of nuclear radiation that scintillation detectors can detect is small and the energy resolution of scintillator detectors is relatively low, which is not suitable for occasions where the nuclear radiation intensity is relatively high like nuclear power plants; nuclear radiation dose Most of the meters are non-automated handheld devices, which require the staff to hold them in hand, which greatly increases the danger of the staff; most of the current mainstream nuclear radiation do...

Problems solved by technology

[0003] Most of them use scintillator detectors, but the range of nuclear radiation that scintillation detectors can detect is small and the energy resolution of scintillator detectors is relatively low, which is not suitable for occasions where the nuclear radiation intensity is relatively high like nuclear power plants; nuclear radiation dose Most of the meters are non-automated handheld devices, which require the staff to hold them in hand, which greatly increases the danger of the staff; most of the current mainstream nuclear radiation dosimeters can only realize the alarm function, and can only detect the radiation intensity qualitatively. not intuitive enough

[0004] In short, the existing nuclear radiation dosimeters need to further improve the detection and analysis output of the nuclear radiation environment, which has become a technical problem to be solved urgently
