Abstract

The concentrations of 210Po and 210Pb have been measured in soil, sediment and rock samples collected from major rivers of coastal Karnataka, viz. Kali, Sharavathi and Netravathi. The activity of 210Po and 210Pb in the samples were separated by radiochemical methods and the activity was counted using ZnS(Ag) alpha-counter. The activity ratio of 210Po and 210Pb and the dependence of organic matter content on the activity of these radionuclides were studied.
