This application discloses methods and apparatus for producing isotopes for use in nuclear medicine, including Actinium-225, Lead-212, Terbium-161, Gold-199, Scandium-47, Copper-64, Copper-67, Bromine-77, and Yttrium-90. A target composition containing a target isotope is irradiated with neutron radiation, where at least 50% of the neutrons come from deuterium-tritium fusion (with no more than 40% from deuterium-deuterium fusion), such as deuterium-tritium fusion generated by lattice confinement fusion in a nuclear fusion reactor. The product isotopes are produced via a nuclear reaction, such as a transmutation reaction.
