Estimation of Radon Concentrations in Groundwater along the Coast of Chennai A City and Estimation of Ingestion Dose
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 4
Abstract
Radon (Rn) is a carcinogenic gas and therefore it is hazardous to inhale since it emits alpha particles. It is radioactive, odourless, colourless, water soluble and the heaviest noble gas. The occurrence and the distribution of radioactivity in water depend on the local geological characteristics of the source, soil, rock and other factors. The underground water often moves through rock and soil containing radon and radon gets soluble in the water. In this study, the result of systematic measurement of activity concentration of 222Rn in drinking water from sources of public water supply along the coastal regions of Chennai City is discussed. The method used in the present study is Radon Emanometry method using alpha counter. From these measurements, the corresponding annual effective ingestion dose is determined. Quantification of 222Rn dose in drinking water of Chennai city will help to understand how safe it is to drink. The results obtained in this study indicate that the 222Rn concentration was in the range of 1.2 to 5.3Bq l−1 with the mean value of 4.3 Bq l−1 for closed well and 2.1 Bq l−1 for open well from the 98 samples collected from different areas of Chennai City. While the average values are within the maximum concentration limit of 11.1 Bq l−1 set by USEPA and world average value of 10 Bq l−1 set by WHO. The effective dose receive by the population of coastal Chennai was found to be varied from 0.004 to 0.019Sv y−1 with a mean value of 0.044 Sv y−1 for closed well and 0.022 Sv y-1 for open well.
