Gamma-emitting radionuclide measurements at the US geological survey national water quality laboratory, Denver, Colorado
January 1, 1982
Like sediment samples from Scofield Resevior in Utah were analyzed for 210Pb by the gamma-ray spectrometric method. The top 10 cm of surface sediment yielded excess 210Pb activity (excluding in situ 226Ra supported 210Pb) of 1.05 pCi/g dry weight and decreased to 0.25 pCi/g at a depth of 25 cm. Based on these data, sedimentation rate was approximately 0.49 cm/y for a total of 30 cm of lake sediment and a lake history of approximately 60 y. An alternative method of 210Pb measurements using wet chemical procedures followed by beta counting gave equivalent results. ?? 1982.
