AUTORADIOGRAM MEASURING METHOD

摘要

PURPOSE:To provide a method to obtain radiograms of a plurality of radiolabeled substances in which images are sufficiently separated from one another and of high accuracy using a stimulable phosphor sheet of a simple constitution by solving problems in autoradiography based on double labeling method employing a photosensitive silver salt film. CONSTITUTION:In an autoradiogram measuring method for obtaining information on the positions of radiolabeled substances labeled with radioisotopes of different average energies, distributed over an organism sample of a living body or a medium sample containing an organism or material derived from the living body, a stimulable phosphor sheet having a protection layer differing in thickness from the sheet or having no protection layer is used. Images corresponding to the distribution of each radiolabeled substance or image signals corresponding to the images are independently obtained by utilizing the difference in the energy transmitted through protection films in the radiolabeled substances.
