Abstract
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.
