Gamma emitting radionuclides and age model of sediment core SIS11-3 from Silbersee, North Germany

The chronology of the top part of the core SIS11-3 is based on excess 210Pb and anthropogenic gamma emitting radionuclides. The analyses of samples down to 66 cm depth were conducted by gamma spectrometry with a reverse electrode coaxial HPGe detector. The efficiencies for the factory characterized detector were calculated using LabSOCS (Laboratory SOurceless Calibration System), a Genie 2000 software calibration tool, based on defined sample to detector geometry and sample density and composition.
