Abstract
A method of recording a radiation image having excellent sharpness which comprises PA0 image-wise exposing to radiation, in combination with the use of a fluorescent intensifying screen, a light-sensitive photographic element comprising a water-proof opaque support, which has an average degree of reflection of about 70 percent or greater, based on the degree of reflection of a magnesium oxide white plate being 100%, in the spectral wavelength region of from about 380 m.mu. to about 600 m.mu., and having on only one surface thereof a coating of a green sensitized silver halide photographic emulsion containing a phenolic color coupler or an .alpha.-naphtholic color coupler, each capable of forming a quinoneimine dye having a maximum absorption within a spectral wavelength region of about 550 m.mu. to about 700 m.mu. on color development, where the silver halide grains of the emulsion have a number average grain size of about 0.5.mu. to about 2.2.mu. and are present in an amount of from about 0.5 g to about 3 g of silver per m.sup.2, and PA0 then subjecting the image-wise exposed light-sensitive photographic element to a color development processing with a phenylene diamine color deve…
