PURPOSE:To obtain the positional information of the radioactive marker substance in a specimen in a desired form for every radioactive marker substance, by using a storing type fluorescent sheet laminate having a plurality of fluorescent layers containing an stimulable phosphor as a photosensitive material. CONSTITUTION:A storing type fluorescent sheet laminate consists of a first storing type fluorescent sheet (a) and a second storing type fluorescent sheet (b). Further, the first storing type fluorescent sheet (a) consists of a protective layer 1a, a phosphor layer 2a and a support 3a while the second storing type fluorescent sheet (b) consists of a protective layer 1b, a phosphor layer 2b and a support 3b. The thickness of at least one sheet is made almost equal to or slightly larger than the max. range of radioactive rays emitted from one radioactive isotope selected from a group consisting of <3>H, <125>I, <14>C and <35>S.
