ABSTRACT:
A mammographic silver halide photosensitive material has at least one photosensitive emulsion layer on either one surface of a support. The emulsion layer is formed of a silver halide emulsion having an iodide content of less than 0.9 mol % based on silver. The photosensitive material exhibits a contrast of 3.7-4.8 as determined by processing the material by specific Developing Process (1). The photosensitive material is combined with a radiographic intensifying screen of Gd.sub.2 O.sub.2 S:Tb phosphor having a CTF of 0.40-1.00 at a spatial frequency of 5 lp/mm to construct a photographic combination.
