Abstract:
1. A method for exposing a stimulable phosphor sheet comprising the steps of superposing a biochemical analysis unit including a substrate capable of attenuating radiation energy and formed with a plurality of absorptive regions spaced apart from each other and selectively containing a radioactive labeling substance and a stimulable phosphor sheet including a support formed with a plurality of stimulable phosphor layer regions to be space apart from each other in substantially the same pattern as that of the plurality of absorptive regions formed in the substrate of the biochemical analysis unit and exposing the plurality of stimulable phosphor layer regions of the stimulable phosphor sheet to a radioactive labeling substance selectively contained in the plurality of absorptive regions of the biochemical analysis unit, the plurality of absorptive regions of the biochemical analysis unit and the plurality of stimulable phosphor layer regions of the stimulable phosphor sheet being formed so that an average area Sm of the plurality of absorptive regions of the biochemical analysis unit and an average area Sp of the plurality of stimulable phosphor layer regions of the stimulable phosphor sheet meet a requirement that Sp is equal to or larger than a quarter of Sm.
