    摘要： In a radiation image recording and read-out system in which a radiation image is once recorded on a recording material comprising a stimulable phosphor layer, the recording material is then scanned with a laser beam, and light emitted from the recording material is photoelectrically read out to reproduce a visible image, a gas ion laser beam having a wavelength shorter than 600 nm is employed as the laser beam. The recording material is fixed on a supporting material, circulated and reused to record radiation images thereon. The apparatus comprises a mechanism for circulating the recording material with respect to the image read-out section by repeatedly moving the supporting material and the image read-out section with respect to each other, and an erasing apparatus for eliminating the radiation energy remaining in the recording material after the read-out step. The supporting material is an endless belt, a rotatable drum or a plate, and the recording material is a continuous phosphor layer or a phosphor sheet.

    摘要： A method of preparing barium fluoroiodide, an iodine-containing barium fluorohalide in which the barium fluoroiodide is used for at least one of materials thereof, and a radiation image conversion panel are provided. In the method of preparing barium fluoroiodide in a suspension preparing step, barium carbonate is added to and mixed with an aqueous solution of hydrogen iodide, such that a molar ratio of the hydrogen iodide to the barium carbonate is 0.5 to 2. A resultant solution is concentrated such that a concentration of barium iodide dissolved in the solution is at least 3.0 mol/l. Then, hydrogen fluoride is added and reacted to generate a precipitate, a rate of addition of the hydrogen fluoride being adjusted such that a molar ratio of the hydrogen fluoride to the barium carbonate added in the suspension preparing step is 0.4 to 0.8 and a theoretical amount of a precipitate of barium fluoroiodide produced during the addition of the hydrogen fluoride is 0.001 to 10 N/min wherein N is an amount of the precipitate of barium fluoroiodide which will finally be obtained. Then, the precipitate is separated.
