Embodiment Construction

[0035] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0036] In the presence of multiple radionuclides such as β-rays and radionuclides other than β-rays, current radiation detectors cannot distinguish other radionuclides, which has certain limitations in practical applications.

[0037] In view of this, in the embodiment of the present invention, at least one first detector and at least two second detectors located on different layers are arranged in the radiation detector, the first detector is used to detect β-rays, and the second detector is used to detect γ-rays ray, even in the case of a variety of radionuclides, it can also distinguish the nuclear elements of β rays from other radionuclides, so it is suitable for various appli...

Abstract

The invention discloses a radiation detector, a radiation detection method and a computer storage medium, which are capable of distinguishing beta rays and other rays, wherein the radiation detector comprises a shielding cover, at least one first detector, at least two second detectors and a processor. A metal shielding material is arranged outside or inside the shielding cover; the at least one first detector is arranged in the shielding cover for detecting radiation of the beta rays; the at least two second detectors are arranged in the shielding cover for detecting radiation of other rays except the beta rays, wherein the at least one first detector is located on the first layer; the at least two second detectors are located on the second layer; the processor is in communication connection with the at least one first detector and the at least two second detectors for receiving first data coming from each first detector, receiving second data coming from each second detector and determining a nuclear element corresponding to the detected beta rays and a nuclear element corresponding to the gamma rays based on the first data and the second data.

Description

technical field [0001] The invention relates to the technical field of nuclear radiation monitoring, in particular to a radiation detector, a radiation detection method and a computer storage medium. Background technique [0002] Radiation detectors are used to identify one or more radionuclides in radiation sources, and usually detect the dose rate levels in radiation sources such as α-rays, β-rays or γ-rays to determine whether they are harmful to the human body. [0003] For β-rays, end-window multiplier tubes are usually used for measurement, but if there are multiple radioactive nuclei in the radiation source, such as β-rays and radionuclides other than β-rays, end-window multiplier tubes cannot Distinguishing other radionuclides has certain limitations in practical applications. Contents of the invention [0004] Embodiments of the present invention provide a radiation detector, a radiation detection method, and a computer storage medium, capable of distinguishing b...
