Description

Some important naturally occuring a and b radionuclides in seventeen brands of drinking water samples collected in Italy were determined. The mean activity concentrations (mBq L-1) of the radionuclides in the water samples were almost in the order: 26±36 (234U) > 21±30 (238U) > 8.9±15 (226Ra) > 4.8±6.3 (228Ra) > 4.0±4.1 (210Pb) > 3.2±3.7 (210Po) > 2.7±1.2 (212Pb) > 1.4±1.8 (224Ra) > 1.1±1.3 (235U) > 0.26±0.39 (228Th) > 0.0023±0.0009 (230Th) > 0.0013±0.0006 (232Th). Based on the HCO3- concentrations and the radionuclide concentrations in the analysed waters, correlation analyses were made, and statistical positive correlations were found among the pairs of 228Ra/226Ra, 226Ra/HCO3-, 228Ra/HCO3-, 210Po/238U, 210Po/226Ra, 228Th/232Th, 228Th/228Ra, 228Th/HCO3- and 210Po/210Pb in drinking water.
