<p><strong>Background:</strong> There is a rapid increase worldwide in the consumption of mineral waters which may contain different level of radioactive elements, especially <sup>226</sup>Ra, in addition to varying amounts of beneficial salts. Therefore, a comprehensive study was planned and carried out in order to determine concentration of <sup>226</sup>Ra natural radionuclide in bottled mineral waters that commercially available in Marmara Region of Turkey. <strong>Materials and Methods</strong>: The method used for <sup>226</sup>Ra concentration analysis bases on the measurement of Radon (<sup>222</sup>Rn) coming from <sup>226</sup>Ra dissolved in the water. The measurements were performed using RAD 7, a solid state α detector, with RAD H<sub>2</sub>O accessory manufactured by DURRIDGE COMPANY Inc. <strong> Results:</strong> The <sup>226</sup>Ra concentration in mineral waters was found to vary from <0.074 to 0.625 Bql<sup>-1</sup> with an average value of 0.267 Bql<sup>-1</sup>.The committed effective doses due to ingestion of 226Ra from the one year consumption of these waters were estimated to range from 10.8 to 90 µSvy<sup>-1</sup>, from 9 to 75 µSvy<sup>-1</sup> and from 3.15 to 26.25 µSvy<sup>-1</sup>, for infants, children and adults, respectively. <strong>Conclusion:</strong> The results obtained in this study indicate that the committed effective doses are below the WHO (World Health Organization) recommended reference level of 100 µSvy<sup>-1</sup>.</p>
