Abstract
Study of radon concentration in drinking water from different sources (groundwater and surface water) used across the Hanumangarh district of Rajasthan, India, was done using scintillation-based detector. The concentration of radon in surface water varied from 0.12 to 2.07 Bq/l with an average value of 0.62 Bq/l and a standard deviation of 0.55 Bq/l and in groundwater samples varied from 1.61 to 8.73 Bq/l with an average value of 4.8 Bq/l and a standard deviation of 2.24 Bq/l. The ingestion and inhalation dose were calculated to assess the health risk for infants, children and adults. The resulting average annual effective dose has been found to be considerably lower than the recommended safe limit of 0.1 msv/y (WHO, In: Incorporating first and second addenda, third ed. WHO Press, Geneva. 3rd ed. World Health Organisation, Geneva, Switzerland, 2008). It can be concluded that radon in water does not pose a significant radiological health risk to the population of the studied area.
