Abstract

According to one embodiment, a radiation detector includes a photoelectric conversion substrate, the scintillator layer, a frame-like sealant adhered to the photoelectric conversion substrate, a moisture-proof cover, and a light reflective layer. The light reflective layer is provided between the scintillator layer and the moisture-proof cover, is fixed to the moisture-proof cover, and is positioned in at least a detection area of the photoelectric conversion substrate. The moisture-proof cover is adhered directly to the sealant and covers the scintillator layer together with the photoelectric conversion substrate and the sealant.

Claims7

Dependent claims

A radiation detector comprising:

a photo-electric conversion substrate including a detection area and a non-detection area outside the detection area;
a scintillator layer provided on the photo-electric conversion substrate and located in at least the detection area;
a frame-shaped sealant located in the non-detection area, surrounding the scintillator layer, and adhered to the photo-electric conversion substrate;
a moisture-proof cover provided above the scintillator layer and located in the detection area and the non-detection area;
and
a light reflective layer provided between the scintillator layer and the moisture-proof cover, fixed to the moisture-proof cover, and located in at least the detection area,
wherein
the moisture-proof cover is directly adhered to the sealant, and covers the scintillator layer together with the photo-electric conversion substrate and the sealant.
