Abstract: A radiation detector includes a scintillator that has a first surface on which radiation is incident and a second surface disposed on a side opposite to the first surface, and that converts the radiation into fluorescence; a sensor unit provided on a side of the second surface of the scintillator and having a light receiving surface that receives the fluorescence converted by the scintillator; and a plurality of members that reflect or absorb the fluorescence converted by the scintillator. Each of the plurality of members has an elongated shape having a longitudinal direction in a direction intersecting the light receiving surface of the sensor unit, and is provided in the scintillator at a position closer to the second surface than to the first surface.

Abstract: Provided is a radiography apparatus capable of changing the shape and size at an imaging site. A radiography apparatus (1) includes a scintillator (12), and a substrate (11) that is laminated on the scintillator (12) and has a plurality of photoelectric conversion elements (17) converting light emitted from the scintillator (12) into electric charges, in which a laminate including the scintillator (12) and the substrate (11) is partitioned into a plurality of blocks (10A) to (10I), and the blocks are separable from each other.

Abstract: An IP cover having a light-shielding property is detachably mounted on an IP. The IP includes a stimulable phosphor layer on one surface thereof. The IP cover is mounted on the stimulable phosphor layer so as to be closely attached to the stimulable phosphor layer. The IP and the IP cover include notches, and a part of an inspection target is inserted into the notches at the time of inspection. An IP unit is mounted on a blade welded portion of an impeller. Radiation is applied from a radiation irradiation device and a radiation image of the blade welded portion is recorded on the IP as a latent image. The IP cover is detached from the IP unit and the IP is set on a template. The IP is set at an image reading position of a radiation image reading device by the template, and the radiation image is read.
