Autoradiographic process

An autoradiographic process for obtaining information on one or two dimensional location of radioactively labeled substances originating from an organism and resolved on a support medium, which comprises:

• (1) placing said support medium and a stimulable phosphor sheet comprising a stimulable phosphor together in layers for a certain period of time to cause said phosphor sheet to absorb at least a portion of radiation energy emitted by the radioactively labeled substances in the support medium;
• and
• (2) separating said stimulable phosphor sheet from the support medium, placing the phosphor sheet and a photosensitive material together in layers, and then irradiating the phosphor sheet with stimulating rays to release at least a portion of the radiation energy stored in the phosphor sheet as stimulated emission, to a portion of which the photosensitive material is exposed to obtain locational information on the radioactively labeled substances as an image thereon, and another portion of which is detected to obtain the locational information as electric signals.

An autoradiographic process for obtaining information on one or two dimensional location of radioactively labeled substances originating from an organism and resolved on a support medium, which comprises:

• (1) causing a stimulable phosphor sheet comprising a stimulable phosphor, which is combined with said support medium in layers or has been integrated together with said support medium, to absorb at least a portion of radiation energy emitted by the radioactively labeled substances in the support medium;
• and
• (2) placing a photosensitive material on the surface of said stimulable phosphor sheet, being opposite to the surface facing the support medium, and irradiating the phosphor sheet with stimulating rays to release at least a portion of the radiation energy stored in the phosphor sheet as stimulated emission, to a portion of which the photosensitive material is exposed to obtain locational information on the radioactively labeled substances as an image thereon, and another portion of which is detected to obtain the locational information as electric signals.
