A simple generator using AG 50Wx8 cation exchange resin has been developed for continual elution of 212Pb and 212Bi from the parent radionuclide 228Th, derived from 232U. Using 0.4 M HCl as an eluent will elute 212Bi while 212Pb is eluted with 2 M HCl. The generator has shown good reproducibility of elution bands. A generator set-up in 2013 has been in continual use over 4 years demonstrating that this generator system has a long and stable lifetime. Furthermore, the generator system presented here has served as a long-term method for attaining no-carrier-added 212Pb and 212Bi radionuclides for homolog studies of flerovium and moscovium.
