The radiation dose and distribution coefficient of 210 Po and 210 Pb concentrations in aquatic environs of major rivers of coastal Karnataka

AbstractThe activity of210Po and210Pb was measured in different matrices of aquatic ecosystem of the major rivers of Coastal Karnataka viz, Kali, Sharavathi and Netravathi. The environmental samples such as surface water, suspended particulate matter and sediment have been subjected to analyses. The activity of these two radionuclides were determined by radiochemical separation of210Po and counting the activity using a ZnS(Ag) alpha counter. The activity ratio of210Po and210Pb and correlation between the activity of these radionuclides were studied. From the measured concentration of210Po and210Pb, the internal Committed Effective Dose to the population for the study area was calculated. The distribution coefficient Kd between water, suspended particulate matter and sediments have been calculated to understand the distribution and accumulation of these radionuclides in different matrices of the aquatic environment.
