A radiation image capturing system includes a radiation source and a radiation image detecting device. The radiation image detecting device includes a solid-state detector and a wavelength conversion layer disposed in this order from a radiation incident side. The wavelength conversion layer has a first phosphor layer having first phosphor particles dispersed in a binder, and a second phosphor layer having second phosphor particles dispersed in a binder. The average particle diameter of the second phosphor particles is smaller than that of the first phosphor particles. The first phosphor layer is disposed on the side of the solid-state detector relative to the second phosphor layer, and joined to or pressed against the solid-state detector. The first and second phosphor particles are distributed in the first and second phosphor layers, respectively, such that the weight of the binder per unit thickness is gradually decreased to the side of the solid-state detector.

A method for preparing barium fluorohalide-based crystal, which includes at least a step in which a halide aqueous solution (B) and aqueous solutions of a fluoride and a barium salt are mixed into a halide aqueous solution (A). The halide aqueous solution (B) contains the same halogen as that contained in the halide aqueous solution (A). In this method, halide ions are used efficiently rather than remaining to form a waste residue.

The present invention provides an emulsion of high silver chloride content tabular silver halide grains with {100} planes as main planes having an excellent color sensitizability, gradation and preservability which can be quickly processed and a photographic light-sensitive material comprising such an emulsion. A novel silver halide emulsion is provided, comprising tabular silver halide grains having {100} planes as two main parallel planes, an aspect ratio of from not less than 2 to not more than 15, a silver chloride content of not less than 60 mol % and a silver salt present on the surface thereof more difficultly-soluble than silver chloride, in a proportion of not less than 50% of all the silver halide grains contained therein as calculated in terms of projected area.

Silver halide emulsion and silver halide photographic material

In a silver halide emulsion, tabular silver halide grains substantially consisting of silver bromoiodide, each having faces as two parallel major faces, an aspect ratio of 2 or more, and an average silver iodide content of 1 mol % or more, account for 50% or more of a total projected area of silver halide grains.
