A signal detecting method in autoradiography, which is applied to an autoradiography having locational information on radioactively labeled substances such as radioactively labeled biopolymers distributed one-dimensionally, being recorded on a stimulable phosphor sheet as a radiation energy-stored image, which comprises steps of: (1) preliminarily scanning a part of the stimulable phosphor sheet with an electromagnetic wave to release a portion of the radiation energy as stimulated emission and detecting the stimulated emission to give an electric signal, to which a signal processing is applied, to determine one-dimensional distribution direction of the radioactively labeled substances; and (2) finally scanning the stimulable phosphor sheet with an electromagnetic wave along said one-dimensional distribution direction to release the radiation energy as stimulated emission and detecting the stimulated emission, to obtain the locational information on the radioactively labeled substances as a digital signal. |
