Distribution of plutonium in Lake Michigan sediments
A study was conducted to obtain baseline information as to the present content of Pu in sediment from Lake Michigan, to determine the utility of Pu isotopes for estimating sedimentation rates, to assess the extent of additional radionuclide inputs to Lake Michigan from nuclear power plants and other sources, and to determine the vertical distribution in recent sediments. Tables are presented to show sedimentation rates and calculated mixing depths, flux normalization factors, and total activity of $sup 239$Pu, $sup 240$Pu, $sup 137$Cs, and $sup 210$Pb in sediment cores taken in 1972, 1973, and 1974. Graphs are presented to show measured $sup 137$Cs, $sup 239$Pb, and $sup 240$Pu profiles in sediment cores and sedimentary columns at various stations during 1972, 1973, and 1974. The significance of the results is discussed. (HLW)
