detection panel; a supporting member having a first surface and a second surface being opposite to the first surface, wherein the radiation detection panel is provided at a side of the first surface; first and second power supply units that supply operating electric power of the radiation detection panel; a housing that accommodates the radiation detection panel, the supporting member, and the first power supply unit; and a holder portion which is provided on the second surface of the supporting member and to which the second power supply unit is detachably attached, the holder portion includes a pair of frames that protrude toward a bottom of the housing which faces the second surface of the supporting member and a concave portion as defined herein, and the bottom of the housing has an opening portion through which the concave portion is exposed. ## Claims ### Claim 1 A radiation detection device comprising: a radiation detection panel; a supporting member having a first surface and a second surface being opposite to the first surface, wherein the radiation detection panel is provided at a side of the first surface; first and second power supply units that supply operating electric power of the radiation detection panel; a housing that accommodates the radiation detection panel, the supporting member, and the first power supply unit; and a holder portion which is provided on the second surface of the supporting member and to which the second power supply unit is detachably attached, wherein the holder portion comprises a pair of frames that protrude toward a bottom of the housing which faces the second surface of the supporting member and a concave portion that is provided between the pair of frames and is capable of accommodating the second power supply unit, and the bottom of the housing has an opening portion through which the concave portion is exposed to an outside of the housing. ### Claim 2 (depends on 1) The radiation detection device
