Abstract

The invention provides a method and device for conducting real-time dynamic tracking positioning on radioactive substances. The device mainly comprises a gamma camera, a visible light video camera and a data processing device. The method includes the steps that the gamma camera receives gamma light quanta which are incident in all the directions of a target angle plane and are defined from the radioactive substances in real time, projection data of the radioactive substances are generated, and the visible light video camera acquires a visible light scene image in the field of view in real time; the data processing device reestablishes the projection data to obtain a gamma radiation image, the gamma radiation image and the visible light image are fused to obtain a dynamic image with radioactive substance quantitative information, and real-time tracking positioning can be conducted on the radioactive substances according to the dynamic image. The method and device for conducting real-time dynamic tracking on the radioactive substances can be applied to a large-scale public place for the stream of people to come and go, tracking positioning can be conducted on the goods with the radioactive substances or radioactive pedestrians, and therefore the safety of the pedestrians at the public places can be improved.

Description

technical field [0001] The invention relates to the technical field of radiation detection, in particular to a method and equipment for real-time dynamic tracking and positioning of radioactive substances. Background technique [0002] The location of radioactive substances, radiation dose measurement, nuclide type identification and activity measurement have a wide range of applications in the fields of nuclear industry, nuclear safety, environmental protection, industrial and medical radioactive source management, and public safety. [0003] Traditional methods used to detect radioactive substances mainly include: dosimeters, gamma spectrometers and gamma cameras. Among them, the gamma camera realizes the two-dimensional plane distribution imaging of radioactive substances by detecting and receiving the gamma photons coded and collimated by the collimator. Moreover, the gamma camera also has the function of measuring the gamma radiation dose rate or particle fluence rate ...
