Radiographic imaging system and silver halide photographic material

A silver halide photographic light sensitive material which is combined with intensifying screens to form a photographic combination for use in a radiographic imaging system for making a radiograph by a radiography apparatus, 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 material is 0.9 to 3.0 m, a distance between the focal point of the X-ray tube and an object is 0.5 to 2.7 m and a distance between the object and the photographic combination is 0.3 to 1.5 m;

• the photographic material comprises a support having a light sensitive silver halide emulsion layer on each of both sides of the support, the photographic material exhibiting a crossover of not more than 15% and an average contrast of not less than 3.4 when the photographic combination is exposed to X-ray and subjected to processing (A), wherein the processing (A) is conducted using a roller transport type automatic processor and the following developer solution (D) and fixed solution (F) at a developing temperature of 35° C. for a developing time of 24 to 28 sec. and at a fixing temperature of 33° C. for a fixing time of 15 to 25 sec.:
