Claim:
1. A radiation image detecting device for carrying out imaging by using a scattered radiation removing grid having radiation absorbing portions for absorbing radiation and radiation transmitting portions for transmitting said radiation alternately and periodically arranged in a first direction, said radiation image detecting device comprising: a detection panel having an imaging surface provided with a plurality of pixels for converting said radiation into an electric signal, for detecting a radiographic image of an object; a plurality of dose detection sensors provided for performing exposure control of said radiographic image, said plurality of dose detection sensors being disposed in said imaging surface periodically with leaving space in said first direction, for detecting a dose of said radiation passed through said object and outputting a signal in accordance with said dose; and an arrangement period of said radiation absorbing portions being different from an arrangement period of said plurality of dose detection sensors in said first direction in said imaging surface, wherein an arrangement period of said dose detection sensors in a second direction orthogonal to said first direction is also different from said arrangement period of said radiation absorbing portions.
