A control unit of a radiation imaging apparatus performs control of moving a radiation source, and emitting radiation from the radiation source at a plurality of positions at which incidence angles of the radiation to a breast of a subject are different from each other. The control unit performs control of causing a radiation detector to detect the radiation emitted from the radiation source at the plurality of positions. The control unit performs control of moving the radiation source at a movement speed corresponding to a position of the radiation source for a subject face proximate position.
