Uranium and Thorium Series Radionuclides in Drinking Water from Drilled Bedrock Wells: Correlation to Geology and Bedrock Radioactivity and Dose Estimation
Natural radioactivity in drinking water from 328 drilled wells was studied in correlation to source parameters. Poor correlation to both aquifer geology and bedrock radioactivity was observed. Concentrations of 238U, 226Ra, 222Ra, 222Rn and 210Po in groundwater samples was in the ranges <0.027-5.3, <0.016-4.9, <0.014-1.24, 5-8105 and <0.05-0.947 Bq.l-1 respectively. In about 80% of the sites the radon concentration exceeds the Nordic recommended exemption level for radon in drinking water and 15% of the sites exceed the action limit. The effective doses from ingestion were calculated and presented in association with geology. Doses due to ingestion ranged between 0.05 and 20.4 mSv.y-1, where the average contribution from 222Rn amounted to 75%. In comparison, the effective doses from inhalation of indoor 222Rn ranged between 0.2 and 20 mSv.y-1. The average contribution from inhalation of 222Rn in air to the total effective dose (ingestion+inhalation) was 58 ± 22%, 73 ± 18% and 77 ± 16% (1 SD) for the age categories 1 y, 10 y and adults respectively.
