Abstract
According to one embodiment, a radiation detector includes a photoelectric conversion substrate having a detection area and a non-detection area, a scintillator layer, a frame-shaped sealant, a cover, and a moisture absorbing layer. A light transmittance of the moisture absorbing layer is changed by changing an amount of moisture in the moisture absorbing layer. The moisture absorbing layer covers the entire scintillator layer in planar view.
