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