Sedimentation Rates, Residence Times and Radionuclide Inventories in Lake Baikal from (137)Cs and (210)Pb in Sediment Cores

Radionuclides in lake sediments may act as indicators of the sedimentation rate of particles on which they are adsorbed. These rates in turn provide an indication of the residence times of particles in the water column. Measurements of the amount of the radionuclide 137Cs (cesium-137) and the natura...

Description
Summary:	Radionuclides in lake sediments may act as indicators of the sedimentation rate of particles on which they are adsorbed. These rates in turn provide an indication of the residence times of particles in the water column. Measurements of the amount of the radionuclide 137Cs (cesium-137) and the natural radionuclide 210Pb (lead-210) in cores from several stations throughout the three basins of Lake Baikal are reported.
