Abstract: A mammography apparatus includes: an arm; a first cooling fan that is disposed on a stand side with respect to the radiation source in the arm, sucks air from an outside of the arm, and discharges air that has cooled the radiation source from a first exhaust port provided on the stand side with respect to the radiation source; a projector that is disposed in the arm; a second cooling fan that is disposed between the projector and the first exhaust port in the arm, sucks a part of air directed from the first cooling fan to the first exhaust port, blows the sucked air toward the projector to cool the projector, and has a flow rate smaller than that of the first cooling fan; and a second exhaust port that is provided separately from the first exhaust port and through which air that has cooled the projector is discharged.

Abstract: A radiography apparatus includes a substrate on which a pixel region in which a plurality of pixels that accumulate charges generated in response to incident radiations are arranged is formed on one surface of a flexible base material, a housing which accommodates the substrate and includes a front portion having an incident surface through which the radiations are incident on the substrate, a first buffer layer which is disposed between the front portion and the substrate in a thickness direction of the housing, the first buffer layer having an outer circumference provided inside the pixel region of the substrate in a plan view, and a structure which is disposed between the front portion and the substrate in the thickness direction at a position overlapping with the first buffer layer.
