Abstract:
The problem to be solved by the present invention is to provide a technique that allows producing a novel radiolabeled compound. The invention is a method for producing a radiolabeled compound, the method including the steps of: irradiating an alloy of a target substance with a radiation beam, to generate two or more radioisotopes from the alloy, and allowing the two or more radioisotopes to migrate into a gas; a step of generating an intermediate label by allowing a first radioisotope, from among the two or more radioisotopes having migrated into the gas, to react with a label precursor; and a step of generating a final label by allowing a second radioisotope different from the first radioisotope, from among the two or more radioisotopes having migrated into the gas, to react with the intermediate label.
