Abstract
Naturally occurring radionuclide 210Po which is an element of 238U decay series, contribute to the radiation that normally people are exposed. Drinking water samples collected from Cauvery river basin of south interior Karnataka State, India were analysed for the activity of 210Po using radiochemical analysis technique. The estimated concentration of 210Po in river water ranges from 0.86 to 4.49 mBq lâ1, and its mean value is 2.67 ± 1.09 mBq lâ1. The concentration of 210Po in bore well water ranges from 1.89 to 4.18 mBq lâ1 and its mean value is 3.22 ± 0.67 mBq lâ1. The dissolved radium concentration in river water varies from 9.09 mBq lâ1 to 55.07 mBq lâ1 with an average of 32.33 ± 14.16 mBq lâ1. Total ingestion dose rate due to 226Ra and 210Po varies from 2.61 to 15.00 μSv yâ1 with a mean value of 8.95 ± 3.74 μSv yâ1, which is less than the recommended value by ICRP (International commission on radiological protection).
