Progress in 14C dating of ice at Utrecht
For 14C dating of ice, only a limitad amount of CO2 is available (20-100 mg C/kg ice). To avoid contamination, a special miling device has been constructed to chip the ice at -20°C. The background of 7.0 +/- 2.0 percent modern carbon (pmC) for a sample of 50 mgC, including extraction and conversion,...
