Radioactivity (Gross-Α and Gross-Β) Studies of Surface Water Collected from Domiasiat Area, West Khasi Hills District, Meghalaya, India

摘要

In this study, the gross activity of the alpha and beta emitting radionuclides present in the naturally occurring water bodies in the Uranium mineralization zone of Domiasiat, West Khasi Hills District, Meghalaya, India was determined. In our study, the gross radioactivity indicates that the water sample under investigation has a low concentration of both alpha and beta emitters and the activity was less than 0.5Bq/l for alpha activity and 1.0Bq/L for beta activity which is lower compared to the WHO prescribed limit. We estimate that the additional equivalent effective dose derived from water consumption is less than 0.3mSv/yr provided the water consumption for the population is on average, 730litres per inhabitant per year. We estimate that the additional equivalent effective dose derived from water consumption is less than 0.3mSv/yr provided the water consumption for the population is on average, 730litres per inhabitant per year (2L per day)
