    摘要： A silver halide photographic light-sensitive material comprising a specific silver halide grain is disclosed. The siliver halide grain contains a localized portion containing 20 mol % or more of silver iodide and average content of silver iodide of which grain is from 0.1 to 10.0 mol %, provided that the silver halide grain is prepared by mixing an aqueous solution containing a water soluble halide compound and an aqueous solution containing a water soluble silver salt under a condition that pAg of the mixture is raised at 9.7 or more during a period after a half amount of the silver salt to be used has been added to the mixture. The photographic light-sensitive material has improved photographic characteristics and is suitable for radiographic use.
