Radiation dose due to uranium in groundwater to the population of Chamarajanagar district, Karnataka, India.

This paper presents the concentration of uranium in 67 groundwater samples of Chamarajanagar district, Karnataka, India, estimated using an LED fluorimeter. The age-dependent ingestion dose to the population of the district is also studied. The concentration of uranium in groundwater varied from 0.20 to 57.50 μg L⁻¹ with an average of 4.40 μg L⁻¹. The annual ingestion dose due to uranium varies from 0.18 to 142.68 μSv y⁻¹, with an average of 7.11 μSv y⁻¹. The ingestion dose received by the population in the study area is less than the recommended level of 100 μSv y⁻¹ by the World Health Organization (2011). [ABSTRACT FROM AUTHOR]
