| Summary: | This study presents the results of 226Ra content in 104 Bulgarian mineral
waters as well as the investigated correlations between the physicochemical
parameters, geological structure, and specific activity of 226Ra. The results
show that the 226Ra activities range from <30 mBqL-1 to 4900 mBqL-1 with a
mean value of 156 mBqL-1. The highest concentrations of 226Ra were measured
in mineral waters originating from the carbonate strata, as the dominant
geological structure. Thus it is well connected with the estimated moderate
positive correlation between Ca2+, Mg2+, and Ra2+ cations in the water. The
estimated annual dose shows large dispersion of values ranging from 6 µSv to
1000 µSv with a mean value of 32 ± 9 µSv. The results demonstrate the need
for further investigation of every mineral water, but greater attention
should be given to the mineral waters with low pH and high content of Ca2+
and Mg2+. |
