Abstract
Regarding to the radiation detector 10, which has the scintillator 16 placed on the light incidence plane plate member of the photomultiplier tube by use of the optical binder 14 interposed therebetween, and which includes a coated film FLM formed so as to cover the scintillator and at least part of the side tube portion 12b of the photomultiplier tube, since the scintillator and the photomultiplier tube are strongly fixed to each other by use of the coating film FLM, so that the size increase of the radiation detector can be suppressed.
Claims10
1--(amended)--. A radiation detector comprising:
- a scintillator placed on a light incidence plane plate member of a photomultiplier tube by use an optical binder interposed therebetween;
- and
- a coated film formed to cover the scintillator and at least part of a tube side portion of the photomultiplier tube,
- wherein an outermost layer of said coated film is an organic film formed through vapor deposition.
The radiation detector according to claim 1,
- wherein said coated film includes a first layer film, a first intermediate layer film, and a second layer film, which are sequentially formed on a base material.
Dependencies are inferred from the claim text.
