A vehicle radioactive substance detection and positioning device and method

Abstract

The present invention proposes a device and method for detecting and locating radioactive substances in vehicles. The device includes: a detector module, a monitoring module, an on-site control data acquisition module, a gate and an uninterrupted power supply module, wherein the uninterrupted power supply module is used to supply The detector module, the monitoring module, the on-site control data acquisition module and the gate power supply, the on-site control data acquisition module performs data analysis according to the background count from each of the detectors and the ray signal, and judges whether the vehicle is on Whether there is radioactive material, if there is no radioactive material, control the opening of the gate and release the vehicle; otherwise, close the gate and trigger an alarm. The invention realizes all-round detection of vehicle radioactive substances and reduces the rate of false positives.

Description

technical field [0001] The invention relates to the technical field of radioactive material detection, in particular to a vehicle radioactive material detection and positioning device and method. Background technique [0002] Radioactive substances refer to substances whose nuclides can decay and spontaneously emit particles or rays. The radiation released during the decay of radioactive substances is essentially a kind of photon energy, which interacts with the molecules and cells of biological organisms, which will lead to changes in their structure and function, causing damage to the cell membrane structure, chromosome distortion, delayed cell division and cell death , thus causing harm to the body, in severe cases, it may cause acute radiation sickness or even the death of the biological body. According to incomplete statistics, there have been more than 1,500 radiation accidents caused by various radioactive substances in my country since 1954. Radioactive substances ...

AI Technical Summary

Problems solved by technology

However, the location of radioactive substances in the motor vehicle and the direction of the beam have a great impact on the detection results. If there are shields such as lead and copper with high radiation attenuation coefficients around the radioactive source, it will greatly reduce the detector's detection rate. Direction detection sensitivity, in this case, using the existing detection technology, it is very easy to miss the detection

In addition, for suspicious large-scale cargo vehicles, the location of radioactive substances is generally carried out by manual inspection, which consumes a lot of manpower and material resources, and is likely to cause personal harm to the inspectors
