Abstract:
In a stimulable phosphor sheet comprising a stimulable phosphor which is employed in a radiation image double-side reading system, radiation energy image erasability on a front side surface onto which stimulating rays are to be applied being lower than that on a back side surface in such manner that a ratio of a difference of an erasing value to a lower erasing value determined on the front side surface or on the back side surface is less than 10%; said erasing value being determined under the following conditions:each surface of the stimulable phosphor sheet is submitted to an erasing procedure in which a ratio of an energy of erasing light applied to the front side surface and an energy of erasing light applied to the back side surface is adjusted to 6:4, 7:3, or 8:2; and the erasing value is calculated on each surface by dividing a quantity of stimulated emission after the erasing procedure by a quantity of stimulated emission before the erasing procedure.
