2. Description of the Related Art Radiation images using X-rays and the like are widely used as medical images for diagnosing diseases. In order to obtain this radiographic image, a fluorescent layer (fluorescent screen) is irradiated with X-rays transmitted through the subject, thereby generating visible light, and using the visible light as a normal photograph using a silver salt film. So-called radiographs, which have been developed by irradiating, have been widely used.

In recent years, a method of directly taking out an image from a phosphor layer without using a film coated with a silver salt has been devised. As this method, the radiation transmitted through the subject is absorbed by the phosphor, and then the phosphor is excited by, for example, light or heat energy, so that the radiation energy accumulated by the absorption by the phosphor is converted into fluorescence. There is a method of emitting an image and photoelectrically converting the fluorescence to obtain an image signal.
