METHOD FOR PRODUCING Ac-225 SOLUTION AND METHOD FOR PRODUCING MEDICINE USING Ac-225 SOLUTION

A method for producing an 225Ac solution includes a step (I) of irradiating a 226Ra target with particles to generate two or more actinium radioisotopes (Ac) including at least 225Ac, a step (II) of dissolving the 226Ra target after the aforementioned step to obtain a solution (1), a step (III) of separating 226Ra and Ac contained in the solution (1) to obtain a solution (2), a step (IV) of allowing Ac contained in the solution (2) other than 225Ac to decay to obtain a solution (3), and a step (V) of separating Ra and Ac contained in the solution (3) to obtain a solution (4). The solution (4) is used to produce a medicine that contains, as an active ingredient, a conjugate between a chelating agent that has formed a complex with 225Ac, and a targeting agent..
