Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a silver halide photographic emulsion and a silver halide photographic sensitive material having improved sensitivity and graininess and improved in lowering of sensitivity and deterioration of image quality due to radiation. SOLUTION: In the silver halide photographic emulsion, 70-100% of the total projected area of all silver halide grains is occupied by plate-like silver halide grains, the average aspect ratio of the plate-like silver halide grains is 20 to 500 and the plate-like silver halide grains include 80 to 100% by number of hexagonal plate-like grains having a ratio of 1.0 to
