    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 a barium fluorohalide phosphor including a mixing step in which phosphor materials are mixed, a firing step in which a resulting mixture of phosphor materials is fired, an annealing step, and a cooling step in which the mixture of phosphor materials is cooled to the ordinary temperature. In the firing step, after the mixture of phosphor materials has been fired at a constant temperature, an atmosphere at the time of the firing is removed while the constant temperature is maintained, and is replaced with an atmosphere different from the atmosphere at the time of the firing, and thereafter, annealing is carried out. In the cooling step, the atmosphere at the time of the firing is removed and replaced with a first different atmosphere, and then first cooling is carried out. Further, the first atmosphere is removed and replaced with a second atmosphere, and then second cooling is carried out. Alternatively, in the cooling step, the atmosphere at the time of the firing is removed and replaced with vacuum or a neutral gas atmosphere, and then cooling is carried out.

    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.
