Abstract (en)
A radiographic screen/film combination has been described comprising a duplitized film sandwiched between a pair of supported or self-supporting X-ray intensifying screens, characterized in that i) said pair of supported or self-supporting X-ray intensifying screens comprises luminescent phosphor particles emitting at least 50 % of their emitted radiation in the wavelength range between 540 and 555 nm, ii) said film comprises, in a light-sensitive silver halide emulsion layer, cubic, ä100ü or ä111ü tabular silver halide grains rich in silver chloride, spectrally sensitized to irradiation in the said wavelength range between 540 and 555 nm by a combination of green sensitizing dyes, being -a benzimidacarbocyanine dye according to the formula (I), given in the description and in the claims and a benzoxacarbocyanine dye corresponding to the general formula (II) given in the description and in the claims. Said radiographic screen/film combination has luminescent phosphor particles, preferably gadolinium oxisulphide phosphor particles, emitting at least 80 % of their emitted radiation in the wavelength range between 540 and 555 nm.
