Abstract
The natural activity concentration levels of 226Ra, 228Ra and 210Pb were analyzed in 17 brands of bottled mineralwaters commercially available in the Southeast region of Brazil. Concentrationsup to 647 mBq . l —1 and 741 mBq . l —1were observed for 226 Ra and 228 Ra, whereas 210Pb concentrationsreached 85 mBq . l —1
