A radiographic screen/film combination or system has been provided comprising a duplitized film sandwiched between a pair of supporting or self-supporting X-ray intensifying screens, characterized in that i) said pair of supported or self-supporting X-ray intensifying screens essentially consists of luminescent phosphor particles emitting at least 50% and more preferably at least 80% of their emitted radiation in the wavelength range shorter than 380 nm, as e.g. a niobium and gadolinium doped, monoclinic M, yttriumtantalate (MYT) phosphor corresponding to formula IYTaO.sub.4 :Gd:Nb (I),ii) said film comprises {111} tabular silver halide grains rich in silver chloride, spectrally sensitive to irradiation in the said wavelength range shorter than 380 nm by the presence of at least one azacyanine dye as a spectral sensitizer.
