Problems solved by technology

[0008] In order to solve the problem that the traditional method of finding radioactive sources is extremely cumbersome and takes a lot of time, which is not conducive to further reducing the harm of radioactive sources to the environment, the present invention provides a positioning method for quickly and accurately locating radioactive sources in a three-dimensional space environment, through This method can quickly and accurately locate radioactive sources, improve the efficiency of handling radioactive source loss accidents, and reduce radiation damage to workers. It is theoretically applicable to all situations where radioactive sources need to be located.

Embodiment Construction

[0030] In order to make the purpose and technical solution of the present invention clearer and easier to understand. The present invention will be further described in detail below in conjunction with the drawings and embodiments. The specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] refer to Figure 1a , S is the radioactive source that needs to be found and located, and its location is unknown. Randomly select four locations in the area where the suspected lost radioactive source is located, and record them as point A, point B, point C, and point O. These four locations are not in the same plane, otherwise the calculation results will be inaccurate.

[0032] Record the dose rate measured at point A as D a , record the dose rate measured at point B as D b , record the dose rate measured at point C as D c , record the dose rate measured at point O as D o . And measure the distance between poin...

Abstract

The invention discloses a positioning method for quickly and accurately positioning a radioactive source in a three-dimensional space environment, which belongs to the technical field of radioactive source positioning. Four positions which are not in the same plane are randomly selected in an area where a suspected lost radioactive source is located, and the four positions are marked as a point A, a point B, a point C and a point O respectively; the coordinates of the radioactive source are calculated according to the relation of the dose rates of the four points, the accurate position of the radioactive source can be obtained by using the least measurement point positions, and the time generated by measurement at different point positions is reduced to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of radioactive source positioning, and in particular relates to a positioning method for quickly and accurately positioning radioactive sources in a three-dimensional space environment. Background technique [0002] With the increasing application of nuclear technology in recent years, there are more and more places where radioactive sources are used. Although the country has strict requirements on the use and storage of radioactive sources, the cases of loss and theft of various radioactive sources Still keeps happening. Lost or stolen radioactive sources will cause great harm to people, animals and plants exposed to the surrounding area, and the longer the time, the greater the harm, so it is necessary to use manpower or use smart devices such as robots with corresponding detectors to use the fastest find and dispose of the radioactive source as quickly as possible. [0003] Now commonly used radioactive...
