Table 3: Average annual effective doses of \({}^{\text{226}}\)Ra uptake in drinking water in the tested mineral water samples. Annual effective doses for children aged 1 to 10 ranged from 3.70 \(\pm\) 0.27 to 12.43 \(\pm\) 2.94 \(\mu\)Sv/a. The mean value for all waters was 6.60 \(\pm\) 1.89 \(\mu\)Sv/a. The annual effective doses for children from 1 to 10 years of age after consumption of individual mineral waters are presented in Figure 4. The mean value is marked with the brown line. Annual effective doses for adolescents aged 10 to 17 ranged from 1.55 \(\pm\) 0.11 to 27.84 \(\pm\) 7.72 \(\mu\)Sv/a. The mean value for all waters was 10.51 \(\pm\) 4.86 \(\mu\)Sv/a. The values of annual effective doses for adolescents aged 10 to 17 years after the consumption of individual mineral waters are presented in Figure 5. The average value is marked with the navy blue line.
