1. A technique in which a radioactive substance is used to produce an image of an object or biological sample by recording the radiation it emits on a photographic plate or detector.
Usage: technical; scientific

Examples

• Autoradiography was used to track the movement of radioactive isotopes through the plant's tissues.
• The researcher employed autoradiography to visualize where the labeled protein accumulated in the cell.
• Autoradiography helped scientists understand the distribution of radioactive compounds in living organisms.
• The autoradiography results showed clear bands corresponding to different molecular weights.
• Modern autoradiography techniques have largely been supplemented by digital imaging methods.
• Autoradiography remains a valuable tool in molecular biology for detecting radioactive markers.
