Concentrations up to 647 mBq·1-1 and 741 mBq·1-1 were observed for 226Ra and 228Ra, whereas 210Pb concentrations reached 85 mBq·1-1. Average committed effective doses of 1.3·10-2mSv·y-1 for 226Ra, 3.4·10-2mSv·y-1 for 228Ra and 9.4·10-3mSv·y-1 for 210Pb 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.173-176openAccessradioactivitynatural radioactivitydrinking waterradium 226radium 228lead 210ingestiondose commitmentsradiation dosesbrazilArtigo de periódico124910.1023/A:1013221922328https://orcid.org/0000-0001-7174-9703
