A radiological image detection apparatus includes a first grating, a second grating, a scanning unit, a radiological image detector, a radiation detection unit, and a control unit. The scanning unit relatively displaces at least one of the radiological image and the second grating to a plurality of relative positions at which phase differences of the radiological image and the second grating are different from each other. The radiation detection unit is provided on a path of the radiation and detects the radiation irradiated to the radiological image detector. The control unit allows the scanning unit to perform a relative displacement operation of the first grating and the second grating in a time period in which a radiation dose detection value of the radiation detected by the radiation detection unit is attenuated to a given level.
