[Solution] A scintillator array 1 is composed of a plurality of scintillator pixels 2 that convert X-rays into light, wherein the plurality of scintillator pixels 2 are arranged in a straight line by partition walls 3 at equal intervals, and the widths of the first side walls 4 and the second side walls 5 at both ends are different, and when two scintillator arrays 1 are placed on top of each other in opposite directions, the scintillator pixels 2 of one scintillator array 1 and the scintillator pixels 2 of the other scintillator array 1 are offset by half a pixel.

The present invention addresses the problem of providing a scintillator panel having high brightness and high sharpness, and a method for producing a scintillator panel. Proposed is a scintillator panel comprising a substrate, a partition wall that is formed on the substrate, and a phosphor that is filled into a space which is partitioned by the partition wall, wherein: an organic protective layer and a metal reflecting layer are laminated, in this order as viewed from the partition wall body side, on at least a surface of the partition wall with which the phosphor comes into contact; the organic protective layer is formed of a resin composition containing a polysiloxane; and condition (A) and condition (B) are satisfied. Condition (A) is that, relative to 100 mol% of the total repeating units, the polysiloxane contains 0.01-65 mol% of a structural unit that is derived from R'Si(OR")3 (where R' and R'' are each a monovalent hydrocarbon group and may be the same or different) and has, in the main chain thereof, an organosilane unit represented by R2SiO2 / 2 (where R is a monovalent hydrocarbon group). Condition (B) is that the organic protective layer does not include a compound having a polymerization initiation capability with respect to the polysiloxane.

Scintillator materials based on mixed garnet compositions, as well as corresponding methods and systems, are described.

A high-brightness scintillator panel is provided that suppresses brightness degradation caused by radiation irradiation. The scintillator panel comprises a substrate and a scintillator layer containing a phosphor, wherein the scintillator layer includes an adhesive resin having a π-conjugated structure consisting of 7 or more atoms, the glass transition temperature of the adhesive resin is 30–430°C, and the film thickness of the scintillator layer is 50–800 μm.

The present invention relates to a scintillator unit and a radiation detector. When the scintillator unit includes a plurality of scintillators and a radiation detector, the scintillator unit can reduce cross talk. More specifically, the scintillator unit includes a reflection layer between the plurality of scintillators and the plurality of scintillators, wherein a low-refractive layer having a lower refractive index than an adhesive layer is sequentially provided on the scintillator between the scintillator and the reflection layer.

This invention provides a radiation image conversion panel that can suppress the degradation of the brightness of a scintillator due to radiation irradiation by controlling the chromaticity of the scintillator's surface, etc. [Solution] The radiation image conversion panel 1A comprises a scintillator layer 40 that converts irradiated X-rays into visible light and emits light, and an element substrate 10 that includes a photoelectric conversion element that receives the visible light emitted by the scintillator layer 40 and converts the received visible light into an electrical signal. On at least one side of the scintillator layer 40, either the side facing the element substrate 10 or the opposite side, the chromaticity b in the CIELab color space is * A colored layer 400 is provided, in which the ratio is 30 or more.
