PROBLEM TO BE SOLVED: To provide a radiation blocking unit, a radiographic imaging apparatus and a radiographic imaging method, capable of improving the coincidence precision between an incidence region of radiation and an incidence region of visible light on an imaging surface.SOLUTION: An radiation blocking unit 60 is attachable to a radiographic imaging apparatus. The radiation blocking unit 60 includes an attachment member 62 which are provided with a radiation blocking part 66 and a visible light blocking part 68. The radiation blocking part 66 transmits the visible light L illuminating an overlapping incidence region 180 in which the incidence region of the radiation R and an incidence region of the visible light L overlap, and blocks the radiation R irradiating regions outside the overlapping incidence region 180. The visible light blocking part 68 transmits the radiation R irradiating the overlapping incidence region 180, and blocks the visible light L illuminating regions outside the overlapping incidence region 180. |
