Problems solved by technology

In order to avoid blocking α and β rays, the middle detection area of ​​the fixed piece is generally designed to be hollowed out, so that the aluminized polyester film of the light-shielding layer and the film fixed piece can only be bonded through the periphery, but this will lead to: The bonding area is not enough, the flatness of the film in the detection area of ​​the light-shielding layer is poor, and the middle part is prone to wrinkles, which seriously affects the appearance of the detection instrument; in addition, the strength of the light-shielding layer is poor and it is easy to deform; when the light-shielding layer When the area is large, because the material is too soft, the installation process is poor. Once wrinkles or scratches occur during the installation process, the light-shielding layer may be scrapped as a whole

Abstract

The invention discloses an αβ measuring instrument. The αβ measuring instrument comprises: a protective piece, including a first grid and a first positioning element; a light-shielding piece, arranged adjacent to the protective piece, including a fixing piece and mounted on the fixing piece At least one film layer, the fixing member includes a second grid and a second positioning element, and the orthographic projection of the first grid and the second grid overlaps in the direction of ray incidence; and the sealing positioning member includes A fixing member engaged with the first positioning element and the second positioning element, the fixing member being arranged to fix the light shield and the shield in the alpha beta meter.

Description

technical field [0001] The present disclosure relates to the technical field of nuclear radiation detection, and more specifically, relates to an αβ measuring instrument. Background technique [0002] The background description provided herein is for the purpose of generally presenting the context of the disclosure. To the extent described in this Background section, the work of the presently named inventors, and aspects of the description that may not constitute prior art at the time of filing, are neither expressly nor impliedly admitted to be prior art with respect to the present disclosure. technology. [0003] The αβ measuring instrument is a common nuclear radiation detection instrument, which can measure the α and β surface activities of personnel equipment and various object surfaces. The detection instrument generally adopts double-scintillation technology, which mainly includes a casing, a protective layer, a silicone sealing sleeve, a light-shielding layer, a pl...
