<p>A method for inspecting and positioning a radioactive substance comprises: providing an environmental background radioactive radiation intensity value; collecting, by using a detector at multiple sampling points on an inspection path, radioactive radiation intensity values of a detected area; calculating a radioactive radiation intensity distribution of the detected area according to the collected radioactive radiation intensity values and the background radioactive radiation intensity value; and determining the position of the radioactive substance according to the radioactive radiation intensity distribution. In addition, a device for inspecting and positioning a radioactive substance comprises: two or more detectors, used for collecting, at each of multiple sampling points on an inspection path, radioactive radiation intensity values of a detected area around the inspection path; and a mobile carrier, used for carrying the detectors to move along the inspection path and pass through the sampling points. With the method and the device, through multi-point observation on the inspection path by using the detectors, the position of the radioactive substance and the radioactive intensity distribution of the detected area can be obtained.</p> |
