Natural radionuclides monitoring in drinking water of Homs city

Radon concentrations, total alpha/beta and radium-226 content in drinking water of Horns city were measured at the sources and in some homes. Results showed that radon concentrations ranged from 2.8 to 153 Bq/L in homes and from 75 to 28.4 Bq/L in sources. In addition, the averages of total alpha, total beta, and radium-226 activity concentration were found for sources 260 +/- 70 mBq\L, 220 +/- 70 mBq\L and 45 +/- 2 mBq\L and for homes 110 +/- 30 mBq\L, 280 +/- 180 mBq\L and 15 +/- 1 mBq\L respectively. Significant differences in concentration were found between the sources and the homes. In general, all results showed that concentrations are within the international allowed limits.
