Radionuclide production system and radionuclide production method

Abstract

A radionuclide production system comprises: an electron accelerator that irradiates an electron beam; a metal target portion that generates Bremsstrahlung radiation by using the irradiated electron beam; an Ra-226 solution target portion that is irradiated by the generated Bremsstrahlung radiation, contains an Ra-226 raw material, can accommodate two or more types of solvents that phase separate, and produces Ac-225 from the Ra-226 raw material when irradiated by the Bremsstrahlung radiation; a solvent extraction part that extracts, from among the two or more types of solvents that phase separate, a first solvent containing a large amount of the Ac-225; a solvent addition part that adds the solvent of the reduced amount that was consumed to the Ra-226 solution target portion; and a radon treatment unit that treats gaseous radon generated by the Ra-226 solution target portion.
