Detector and detection method for searching nuclear radioactive source in air

Abstract

The invention discloses a detector for searching nuclear radioactive sources in the air and a detection method, the detector is fixed on an unmanned aerial vehicle, and the detector comprises a detector shell, the peripheral wall of the detector shell is provided with a radioactive source detection probe a according to the eight directions of east, south, west, north, northeast, southeast, northwest and southwest; a radioactive source detection probe b facing the vertical direction of the ground is installed in the middle of the bottom end face of the detector shell, and a wireless data transmission module and a GPS positioning module are installed on the detector shell. One end of each detector hanging rack is fixedly or hinged to the top end face of the detector shell, and the other end of each detector hanging rack is connected with the unmanned aerial vehicle; and the main control board is arranged in the detector shell. The detector is carried on the unmanned aerial vehicle, the nine probes in different directions are used for all-directional detection of the nuclear radioactive source, and the detector has the advantages of being high in maneuvering performance, small in environmental factor influence, capable of being remotely controlled and wide in detection range and has the effect of rapidly and accurately searching for the nuclear radioactive source.

Description

technical field [0001] The invention relates to the technical field of nuclear emergency radiation environment monitoring, and more specifically relates to a detector and a detection method for searching nuclear radioactive sources in the air. Background technique [0002] Nuclear safety is the prerequisite for the sustainable development of the nuclear technology application industry. Nuclear emergency monitoring is one of the important tasks to ensure nuclear safety. Especially in the event of a nuclear accident, in order to search for lost radioactive sources or investigate radiation leakage points, the radiation environment monitoring data can be used to fully grasp the situation of the accident site, and provide auxiliary decision-making support for further emergency response to nuclear accidents. [0003] However, traditional fixed or handheld radioactive monitoring equipment has poor mobility and cannot be quickly deployed to some critical and dangerous areas, especi...

AI Technical Summary

Problems solved by technology

[0003] However, traditional fixed or handheld radioactive monitoring equipment has poor mobility and cannot be quickly deployed to some critical and dangerous areas, especially in the extremely complex internal environments of large nuclear facilities such as nuclear reactors or nuclear power plants, and there are high levels of radiation Dose area, difficult to monitor at close range

If workers enter these areas to carry out monitoring work, they may be exposed to high doses of radiation damage; and ground radiation environmental monitoring robots are mostly limited by terrain and environmental factors, and cannot guarantee to reach all designated monitoring locations
