An $$alpha$$ radioactive nuclide $$^{211}$$At is a prospective candidate for utilization in targeted alpha radiotherapy. We have started nuclear and radiochemical study of production and utilization of radioactive astatine isotopes using lithium ion beams at the tandem accelerator of JAEA-Tokai. We determined the excitation functions of astatine isotopes in the reaction of 29-48 MeV $$^7$$Li+$$^{nat}$$Pb and studied a chemical behavior of carrier-free radioactive astatine isotopes with a dry-chemistry method. Details will be shown in the presentation.

Production of astatine radioisotopes in the $$^7$$Li+$$^{nat}$$Pb reaction and simple chemical separation of astatine

We have started to study production and utilization of an $$alpha$$ radioactive nuclide $$^{211}$$At which is a prospective candidate for targeted alpha radiotherapy. We determined production cross sections of astatine radioisotopes in the reaction of 29-48 MeV $$^7$$Li+$$^{nat}$$Pb by $$alpha$$-ray and $$gamma$$-ray spectrometry at the tandem accelerator of JAEA-Tokai. Besides, we developed a simple dry-chemical method for separation of astatine.
