    摘要: In a radiographic image conversion method in which a stimulating light is irradiated to a panel storing a radiation energy in the form of an image to reproduce and then to read out the image, the response speed of a stimulation and the reading speed of a radiographic image area increased by making use of (1) a phosphate type phosphor having the composition, xM.sub.3 (PO.sub.4).sub.2.NX.sub.2 :yA or M.sub.3 (PO.sub.4).sub.2 :yA, which is a highly sensitive phosphor capable of readily releasing the stored energy when a stimulating light is irradiated to the phosphor, and (2) the stimulating light having the range of the wavelengths from a visible ray of not shorter that 500 nm to an infrared ray.
