Radiation detector

According to one embodiment, a radiation detector includes, a substrate, a scintillator layer, a moistureproof body, and an adhesion layer. The substrate comprises a photoelectric conversion element. The scintillator layer is formed on the substrate and converts radiation into fluorescence. The moistureproof body comprises a flange portion in a periphery thereof, the moistureproof body being deep enough to contain at least the scintillator layer. The adhesion layer causes the substrate and the flange portion of the moistureproof body to adhere to each other in a sealed manner.

Radiation detector and method for producing the same

In a radiation detector in which scintillator layers are directly formed on all the light receiving parts of a plurality of photoelectric conversion substrates, space and level difference between the adjacent photoelectric conversion substrates are determined so that the effects of these space and level difference fall within a range corresponding to the effect of one photoelectric conversion element. Specifically, the space between the adjacent photoelectric conversion substrates is equal to or less than 133 &#x3bc;m and the level difference between the adjacent photoelectric conversion substrates is equal to or less than 100 &#x3bc;m. Accordingly, the scintillator layers can be directly formed on all the light receiving parts of the plurality of photoelectric conversion substrates. This prevents degradation in MTF and sensitivity and reduces manufacturing costs.

A radiation detection apparatus includes a radiation detection panel having a fluorescent film and photoelectric conversion elements, a support board for supporting the radiation detection panel, and a gel member displaced between the radiation detection panel and support board.
