An radiographic imaging system for making a radiograph by a radiography apparatus using a photographic combination of a silver halide photographic material having light sensitive layers on both sides of the support and an intensifying screen is disclosed, wherein the photographic material exhibits a cross-over of not more than 15%, a specified point gamma value within the specified density range on the characteristic curve when the photographic combination is exposed to X-ray, and wherein the radiography apparatus conducts making a radiograph under the condition that a distance between a focal point of an X-ray tube and the photographic combination is 1.0 to 3.0 m and a distance between an object and the photographic combination is 0.2 to 1.5 m.
