Abstract

The invention provides a locator for monitoring a radioactive source. The locator comprises a detector used for detecting the radioactive source and generating a detector image of the radioactive source, a camera parallel and level to the detector in the vertical direction, and used for shooting a visible light image of the radioactive source, and a phase difference adjusting device used for adjusting a shooting region of the camera to enable the detector and a camera head of the camera to be in the same axial direction, so as to eliminate a phase difference between the radioactive source on the detector image and the radioactive source on the visible light image. By the adoption of the locator, the phase difference between the radioactive source on the detector image and the radioactive source on the visible light image can be eliminated. The invention further provides a method for monitoring the radioactive source.

Description

technical field [0001] The invention relates to the technical field of radioactive source monitoring, in particular to a locator for monitoring radioactive sources and a method for monitoring radioactive sources. Background technique [0002] In some radioactive material monitoring equipment, in order to calibrate the position of the radioactive source, the monitoring screen mainly consists of two parts: a detector image and a visible light image. The detector image is obtained by the detector using radiation detection technology, and the visible light image is obtained by the camera through video surveillance technology. However, in the monitoring screen, there is a certain deviation between the radioactive source position calibrated by radiation detection and the radioactive source position in the video surveillance screen. . Contents of the invention [0003] This application is based on the inventor's discovery of the following facts and problems: the inventor found t...
