Abstract

The invention discloses a detector device rapidly and accurately locating a radioactive source as well as a location method. By virtue of the device, the radioactive source can be rapidly and accurately located, and the device is mainly used for finding a lost radioactive source. By virtue of the device, the aims of improving efficiency of handling a radioactive source loss accident and reducing damage of radiation on workers are achieved. The device comprises a circuit electronic module, a fixed bolt, a circular ring provided with a threaded hole, an end cover shielding structure, a radioactive detector, a fixed seat for the radioactive detector, a main body shielding structure and a base shielding structure. The device performs accurate measurement on dosage rates in different directionsby virtue of reasonable combination of multiple detectors and shielding structures, a circuit electronic system is adopted for calculating the dosage rates in different directions, and finally a location of the radioactive source is accurately obtained. By virtue of the device, the aims of improving the efficiency of handling the radioactive source loss accident and reducing the damage of the radiation on the workers are achieved.

Description

technical field [0001] The invention belongs to the technical field of radioactive source positioning, and in particular relates to a detector device and a positioning method for rapidly and accurately locating radioactive sources. 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] The commonly used radioactive source detectors are ...
