The experimental conditions for separation of Ra from Ba with cation exchange technique by using 133Ba
224Ra and 212Pb as tracers
and 0.1 mol/L (NH4)2H2EDTA-0.3 mol/L NH4Ac solution as eluent are studied. A proce-dure suitable for separation of Ra from the ThO2 targets irradiated by 60 MeV/u 18O ions is developed. The results demon-strate that the decontamination effect for main reaction products
specially radioactive Ba isotopes
is satisfactory. The chemical yield of Ra is more than 70%.
