Embodiment 2

[0056] Embodiment 2: This embodiment provides a radiation source positioning system, which includes a processing unit, and two radiation source detectors are symmetrically arranged along a fixed point, which are a first radiation source detector and a second radiation source detector respectively. ; The third radioactive source detector in the third position. The first radiation source detector, the second radiation source detector and the third radiation source detector are all arranged on the detector movement mechanism that can move along a specified route; for example, the specified route can be centered on the fixed point The circular motion of the detector can also be other specified routes, such as square route, triangular route, straight line, specified radian curve; the first radiation source detector and the second radiation source detector can be set along the same detector motion mechanism. The specified route movement can also be set on different detector movement...

Abstract

The invention relates to the radioactive source positioning field, and especially relates to a radioactive source positioning method and system. Multiple radioactive source detectors in different relative positions are adopted to carry out more than two times of detection on radioactive sources, and comparison is conducted on the basis of different detection results, so false positions during detection of the radioactive sources are removed. The radioactive source positioning method and system are simple in realization way, low in calculation complexity, and high in calculation precision.

Description

technical field [0001] The invention relates to the field of radioactive source positioning, in particular to a radioactive source positioning method and a positioning system. Background technique [0002] With the development of science and technology, the safe application of radioactive sources has become more and more popular, but with the increase in the application of radioactive sources, the problem of loss of radioactive sources has gradually emerged. As we all know, radioactive sources are destructive and destructive in unshielded environments. Long cycle and so on. Once any radioactive source is lost, it will cause serious radiation damage to the people around the accident area, and even cause social panic. Therefore, it is particularly important to quickly search for lost radioactive sources. [0003] At present, after the radioactive source is lost, NaI(Tl) detectors are usually used to search and locate. When a single NaI(Tl) detector detects a radioactive sour...
