Abstract |
|
|
| The natural radionuclide 210Po is widely existing in the terrestrial environments and also presenting in the Earth’s crust because of the decay of 238U. The presence of the above mentioned radionuclide in the atmosphere is due to the decay of 222Rn, diffusing from the Earth ground. In the present study, the concentration of natural 210Po in the sediment samples from Periyakalapattu to Parangipettai of East Coast of Tamilnadu, India was measured using Radiation Counting System with an alpha counter of ZnS (Ag) detector. The distribution ranges of 210Po activity in the sediment samples were determined as 2.38±0.33 - 6.62 ± 0.52 Bq kg-1 with a mean value of 3.97 ± 0.3 Bq kg-1. The annual committed effective dose of 210Po consumed by the public was estimated. The results obtained from this study were compared with the values of earlier studies carried out in India and other countries and thus the final conclusion was reported. |
