Abstract: A scintillator includes a plurality of columnar crystals. A surface protection film is made of poly-para-xylyene and covers a surface of the scintillator, and the front ends of the columnar crystals penetrate thereinto. A photoelectric conversion panel includes a glass substrate and an element unit formed on the glass substrate. The element unit includes a plurality of pixels, is disposed opposite to the front ends of the columnar crystals, and detects visible light which is emitted from the front ends and is transmitted through the surface protection film in a light receiving region of each pixel so as to be converted into electric charge. To improve an SN ratio, a penetration amount P of the front end into the surface protection film and an area A of the light receiving region of each pixel are set to satisfy a relationship of 0 m?1<P/A?1.4×103 m?1.

Abstract: Generation of dark current due to emission of back lighting to radiation image detectors is sufficiently suppressed. A radiation image detecting apparatus includes a radiation image detector and a light emitting section. A biasing electrode to which a biasing voltage is applied, a photoconductive layer for generating electric charges when irradiated with recording electromagnetic waves bearing a radiation image, a substrate side charge transport layer for transporting the electric charges which are generated in the photoconductive layer, and an active matrix substrate provided with a plurality of charge collecting electrodes for collecting the electric charges which are generated in the photoconductive layer, are laminated in this order to form the radiation image detector. The light emitting section emits light onto the radiation image detector at least during irradiation of the recording electromagnetic waves. The average composition of the substrate side charge transport layer is SbxS100-x (41?x?60).

Abstract: A radiation image conversion panel includes a substrate and a phosphor layer formed on the substrate by a vapor-phase deposition method. The phosphor layer has a columnar crystal structure and the columnar crystal structure accounts for 50 to 65% of the phosphor layer in terms of relative density. The panel requires a smaller quantity of erasing light and hence is suitable for application in a small type of radiation image information recording and reading apparatus.

Abstract: The step of erasing radiation energy remaining in a radiation image storage panel having an energy-storing phosphor layer composed of a phosphor in the form of columnar crystals and having been subjected to the step for reading a radiation image recorded in the storage panel according to a radiation image recording and reproducing method can be performed using an erasing light in an amount which is determined from an amount of the radiation having been applied to the storage panel.

Abstract: A process for reading a radiation image out of a radiation image storage panel which has a phosphor layer comprising columnar crystals of europium activated cesium halide stimulable phosphor in which a radiation image is recorded, is performed by the steps of: exposing the storage panel to stimulating light in a stimulating energy of 2 to 10 J/m2; photoelectrically collecting a stimulated emission given off from the storage panel; and converting the collected emission into a radiation image in the form of a series of electric image signals.

Abstract: The process for producing a radiation image conversion panel forms a phosphor layer on a substrate by vapor-phase deposition in a vacuum chamber and subjects the formed phosphor layer to a thermal treatment to obtain the radiation image conversion panel. The phosphor layer is protected by a selectively permeable cover after completion of the vapor-phase deposition until completion of the thermal treatment. Or the foreign matter on a surface of the phosphor layer is removed prior to the thermal treatment performed on the phosphor layer.
