Disponível em: http://repositorio.ipen.br/handle/123456789/14007.http://repositorio.ipen.br/handle/123456789/14007The natural activity concentration levels of 226Ra, 228Ra and 210Pb were analyzed in 17 brands of bottled mineral waters commercially available in the Southeast region of Brazil. Concentrations up to 647 mBq. l –1 and 741 mBq. l –1 were observed for 226Ra and 228Ra, whereas 210Pb concentrations reached 85 mBq. l –1. Average committed effective doses of 1.3. 10–2 mSv. y–1 for 226Ra, 3.4. 10–2 mSv. y–1 for 228Ra and 9.4. 10–3 mSv. 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.openAccessopenAccessradioactivitynatural radioactivitydrinking waterradium 226radium 228lead 210ingestiondose commitmentsradiation dosesbrazilTexto completo de evento10.1023/A:1013221922328https://orcid.org/0000-0001-7174-9703
