We have started to study production and utilization of an 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 Li+ $^{nat}$ Pb by -ray and -ray spectrometry at the tandem accelerator of JAEA-Tokai. Besides, we developed a simple dry-chemical method for separation of astatine.
