Abstract
A time efficient method has been developed for separation and measurem ent of Pb-210 and Pb-212 and its progenies in aerosol samples. After l eaching, transferring to a sulphate system and adding a certain amount of HCl, Po and Pi isotopes are extracted into a liquid scintillation cocktail and measured simultaneously using pulse shape analysis. Pb-21 0 is measured from the ingrown Bi-210 after ca 2 weeks or measured dir ectly in the aqueous phase. The lower limits of detection are 0.2 mBq for Po-210 and Bi-212, and 0.5 mBq for Bi-210.
