Problems solved by technology

Such light-shielding films are formed by vapor-depositing aluminum on a very thin plastic film, but they are easily damaged. In addition, each light-shielding film is a structure held in the air, so from the structural point of view, the strength of its external force very weak

Embodiment Construction

[0033] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0034] figure 1 A method for manufacturing the scintillator member 10 is shown. In the radiation measuring apparatus, the scintillator unit 10 is used as a radiation detector. The scintillator unit 10 is composed of a scintillator plate 16 and a film 14 .

[0035] figure 1 This is an embodiment in which one film is formed on the surface (radiation incident surface) of the scintillator plate 16 , but a plurality of films may be formed on the surface of the scintillator plate 16 .

[0036] The scintillator plate 16 is constructed of a plastic scintillator material. As is well known, when radiation enters the scintillator member 16, light is emitted, and the inner surface side of the scintillator plate detects the emitted light. Several types of radiation include X-rays (γ-rays), β-rays, and α-rays, and the scintillator member 10 in th...

Abstract

When a heating process is performed in a state where a thermal transfer sheet is superimposed on a scintillator plate, a film of the thermal transfer sheet is separated from the thermal transfer sheet and adhered onto the scintillator plate. The film includes a protective layer, an aluminum layer, and an adhesive layer. The aluminum layer is protected by the protective layer. Because the scintillator plate by itself functions as a rear surface support substrate with respect to the protective layer and the aluminum layer, a film which is highly resistive against an external effect can be formed. A plurality of films can be layered on the scintillator plate. A pressure transfer method can also be used for formation of the film. A scintillator member in which the film has been formed is disposed in a radiation measuring device.

Description

technical field [0001] The invention relates to a scintillator component, its manufacturing method, and a radiation measurement device, in particular to the light-shielding technology related to the scintillator component. Background technique [0002] Scintillator parts are used in various radiation measurement devices such as surface contamination detectors and body surface controllers. When radiation enters the scintillator unit, the generated light is guided to the light-receiving surface of the photomultiplier tube (PMT). In order to detect light generated on the scintillator member with high sensitivity, a light-shielding structure (dark room) is provided on the back side of the scintillator member to block external light, and a light-shielding structure may also be provided on the front side of the scintillator. [0003] When the front (radiation incident surface) side of the scintillator member is shielded from light, radiation passes through the front side of the s...
