  • Patent number: 10705227
    Abstract: [Problem] Provided is a layered structure in which a non-scintillator layer is utilized as a light transmission path to a sensor so as to transmit light in a vertical direction through the non-scintillator layer without allowing the light to re-enter a scintillator layer. [Means for Solution] Provided is a scintillator panel having a structure in which a scintillator layer and a non-scintillator layer are repeatedly arranged in a direction substantially parallel to a radiation incident direction. In this scintillator panel, the scintillator layer contains at least a phosphor, a binder resin, and voids; the non-scintillator layer is radiolucent; the scintillator layer and the non-scintillator layer have an irregular structure at their interface; and an arithmetic surface roughness Ra attributed to irregularities is 1/400 to 1/10 of the width of the non-scintillator layer.
