Problems solved by technology

Radiation detection equipment judges whether there are radiation sources and nuclear materials by detecting whether there are gamma and neutron radiation, but cannot locate the existence of radiation sources and nuclear materials
Locating sources of radiation generally requires additional equipment and methods, thereby extending the response time of frontline law enforcement personnel

Abstract

The invention discloses a radiation monitoring device, and the device comprises a plurality of detectors arranged in the moving direction of a radiation source, wherein the visual field range of the detectors is divided into two-dimensional plane grids at the position of the radiation source, and rays emitted by the radiation source are detected by at least one of the plurality of detectors in a unit time interval; a data acquisition module which is used for acquiring a signal detected by at least one of the plurality of detectors; and a data processing module which is used for converting thesignals acquired by the data acquisition module into digital signals with position information so as to determine the position of the radiation source. The device can locate the orientation of the radiation source through the change of the dynamic data of the detector, gives a two-dimensional image in combination with the optical camera, identifies and determines a carrier, and realizes early warning.

Description

technical field [0001] The invention relates to the field of nuclear security, in particular to a radiation monitoring device and method. Background technique [0002] With the application of nuclear and other radiation sources and the distribution of nuclear facilities more and more widely, radiation detection equipment has been widely used in land, railway border ports, airports and seaport inspection sites. Radiation detection equipment judges whether there are radiation sources and nuclear materials by detecting gamma and neutron radiation, but cannot locate the existence of radiation sources and nuclear materials. Locating radiation sources generally requires additional equipment and methods, thereby extending the response time of frontline law enforcement personnel. Contents of the invention [0003] A brief overview of the application is given below in order to provide a basic understanding of certain aspects of the application. It should be understood that this s...
