摘要：
The natural activity concentration levels of (226)Ra, (228)Ra and (210)Pb were analyzed in 17 brands of bottled mineral waters commercially available in the Southeast region of Brazil. Concentrations up to 647 m.Bq.l(-1) and 741 mBq.l(-1) were observed for (226)Ra and (228)Ra, whereas (210)Pb concentrations reached 85 mBq.l(-1). Average committed effective doses of 1.3.10(-2) mSv.y(-1) for (226)Ra, 3.4.10(-2) mSv.y(-1) for (228)Ra and 9.4.10(-3) mSv.y(-1) for (210)Pb were estimated for the ingestion of these waters. A collective dose of 90 manSv was evaluated, considering the annual production of the bottled mineral waters analyzed in this study.
