As a continuation of previous work (Kmak et al. in J Radioanal Nucl Chem 314:985–989, 2017), an isotope generator column based on the 210Pb decay chain has been made to produce highly radiopure 210Po. Two replicate studies were performed on AG 50Wx8 columns with an average yield of 90.4 ± 1.9%. 210Pb breakthrough was seen at the 6 month elution for both generators.
