Radiation detection apparatus
According to one embodiment, a radiation detection apparatus includes a radiation detection panel, a support member, a circuit board, a flexible circuit board, a housing, a connecting member, a thermally radiative member, and a thermally conductive member. The support member supports the radiation detection panel on one surface thereof. The circuit board is supported by other surface of the support member, and drives the radiation detection panel. The flexible circuit board electrically connects the radiation detection panel with the circuit board, and on which an integrated circuit is mounted. The housing has thermal insulation, and a part of which is provided with an opening. The connecting member is connected to the support member and the housing. The thermally radiative member is located outside the housing and extends through the opening. The thermally radiative member is opposed to the integrated circuit, and shields an electromagnetic field that leaks from the opening.
