A radiation image acquisition device includes: a radiation source which emits radiation; a wavelength conversion member of a flat plate shape which generates scintillation light according to incidence of the radiation emitted from the radiation source and transmitted by an object; first imaging means which condenses and images the scintillation light emitted from an entrance surface for the radiation in the wavelength conversion member; and second imaging means which condenses and images the scintillation light emitted from a surface opposite to the entrance surface in the wavelength conversion member, wherein one of the first imaging means and the second imaging means condenses the scintillation light emitted from the entrance surface or the opposite surface in a direction of a normal thereto, and wherein the other of the first imaging means and the second imaging means condenses the scintillation light emitted from the entrance surface or the opposite surface in a direction inclined with respect to a direction of a normal thereto. |
