ASSESSMENT OF AVERAGE ANNUAL EFFECTIVE DOSE AND STUDY OF RADON CONCENTRATION IN DIFFERENT TYPES OF WATER SAMPLES

Radon and its decay products are the main source of natural radiation exposure. Alpha particle emissions of radon in drinking water increase the absorbed dose by the respiratory and gastrointestinal systems, which can lead to cancer. In the present study, annual effective dose and radon concentration measurement has been carried out in four different types of water samples i.e. (mineral water, distilled water, tape water and surface water) in Shahjahanpur city of Uttar Pradesh by using sensitive plastic track detector (CR-39). It is observed that our results are less than the maximum contaminant level of 11Bq/L (300pCi/L) and 1-10mSv/y for annual effective dose for the US Environmental Protection Agency.
