“…As far as the measured radionuclides are concerned, the mean dose contribution Ra,232 Th, 137 Cs, 40 K, gross alpha and gross beta in mineral water samples were compared with different countries of the world in Table 4. For 226 Ra, the minimum value measured is higher than that of the other countries mentioned in the Table 4; again for 226 Ra, the maximum value measured in this study is higher than Brazil (Godoy et al 2001), Algeria (Amrani 2002), Iran (ShahbaziGahrouei and Saeb 2008) and Italy (Desideri et al 2007); however, it is lower than Poland (Chau and Michalec 2009), Hungary (Kovacs et al 2004) and Poland (Kozlowska et al 2007). While the maximum value found in this study for 232 Th is higher than that of Algeria, 40 K, gross alpha and gross beta concentrations are generally lower than the literature.…”

This study has evaluated the levels of natural radionuclides and chemical components of mineral waters in the Eastern Black Sea Region (Turkey). The mean activity concentrations of (226)Ra, (232)Th, (137)Cs, (40)K, gross alpha and gross beta were found as 129, 33, 28, 714, 125 and 170 mBq L(-1), respectively. Due to consumption of mineral waters, the radiological impact of them on the inhabitants was calculated by taking the annual intake into account through ingestion of aforementioned radionuclides. The estimated effective doses from mineral water were found to be 13.20 μSv year(-1) ((226)Ra), 2.74 μSv year(-1) ((232)Th), 0.13 μSv year(-1) ((137)Cs) and 1.62 μSv year(-1) ((40)K). The overall contribution of these radionuclides to the committed effective dose from a year's consumption of mineral water in the region is therefore estimated to be only 17.69%, which is in concordance with the recommended WHO value (100 μSv year(-1)). The chemical analysis results showed that these waters contain Na, Al, P, Cl, K, Ca, V, Mn, Fe, Ni, Cu and Zn elements. These values were evaluated and compared with the internationally verified values. This study provides important information for consumers and authorities because of their internal radiochemical exposure risk from mineral water intake.

“…Assuming that every adult drinks 1 L/day, the annual effective doses caused by intake of the 226 Ra, 232 Th, 137 Cs and 40 K isotopes were calculated (Chau and Michalec 2009;Kovacs et al 2004). E is the ingested dose conversion factor for the radionuclide (Sv Bq −1 ).…”

“…A number of studies have been carried out in different parts of the world to study the occurrence of U in waters (Chau and Michalec 2009;De Camargo and Mazzilli 1996;Killiari and Pashalidis 2010) and to evaluate its chemical and radioactive toxicities. In 2012, the World Health Organization (WHO) proposed a provisional guideline of 30 lg l -1 for U, which was based on its chemical toxicity.…”

Uranium is a radioactive element normally present in hexavalent form as U(VI) in solution and elevated levels in drinking water cause health hazards. Representative groundwater samples were collected from different litho-units in this region and were analyzed for total U and major and minor ions. Results indicate that the highest U concentration (113 µg l(-1)) was found in granitic terrains of this region and about 10 % of the samples exceed the permissible limit for drinking water. Among different species of U in aqueous media, carbonate complexes [UO2(CO3)(2)(2-)] are found to be dominant. Groundwater with higher U has higher pCO2 values, indicating weathering by bicarbonate ions resulting in preferential mobilization of U in groundwater. The major minerals uraninite and coffinite were found to be supersaturated and are likely to control the distribution of U in the study area. Nature of U in groundwater, the effects of lithology on hydrochemistry and factors controlling its distribution in hard rock aquifers of Madurai district are highlighted in this paper.
