Abstract

In this study the age and sediment accumulation rates of the lake sediment were calculated by using the Pb-210 concentrations through the sediment core. The specific activity of Pb-210 for each sediment section was determined by LSC with double energetic window method which relies on the direct determination of 210Pb without waiting for the in growth of Po-210 from Pb-210. For the successful determination of this radionuclide two counting windows were optimized to eliminate the overlapping of the beta spectra of (21) Pb and Bi-210. (C) 2014 Elsevier Ltd.
