“…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 ).…”

“…The content of 226 Ra and 228 Ra isotopes, originating from the 238 U and 232 Th decay series, was quite low in the analyzed bottled mineral waters, compared to the values obtained for other bottled mineral waters 3,4 and the investigated spring waters (Crni Guber, Studenica and^ibutkovica).…”

“…[2][3][4] Knowledge of the concentrations of uranium and radium in drinking water is important because an appreciable fraction of the absorbed uranium and radium is deposited in bones, with a corresponding contribution to the internal dose. These are the waters from Serbia (Studenica,^ibutkovica) and one from Bosnia and Herzegovina (Crni Guber).…”

In this work, a study of the radioactive content of some spring and bottled mineral waters originating from metamorphic rock areas was carried out. A high content of radium isotopes ( 226 Ra, 228 Ra), was found by radiometric analysis in the spring waters: Studenica ( 226 Ra: 289 mBq/L),^ibutkovica ( 226 Ra: 92, 4 mBq/L, 228 Ra: 610 mBq/L), and Crni Guber ( 226 Ra: 120 mBq/L, 228 Ra: 1170 mBq/L). On the other hand, the radiochemical results showed a higher concentration of 238 U in the bottled mineral water samples (dissolved uranium concentrations were from 0.21 mBq/L, for "Kopaonik" to 71.5 mBq/L fo "Skadarska") than in the spring water samples (dissolved uranium concentrations were very low » 10 mBq/L). The concentrations of all the present naturally occuring radionuclides: 238 U, 234 U, 232 Th, 230 Th, 228 Th, 228 Ra and 226 Ra were determined by alpha/gamma spectrometric analysis. The activity ratios 234 U/ 238 U, 226 Ra/ 230 Th and 228 Th/ 232 Th, 228 Ra/ 228 Th were calculated and are discussed as an indication of the radioactive disequilibrium in bothe the 238 U and 232 Th radioactive series. The high contents of radium isotopes with respect to the equilibrium values expected from the respective parents 232 Th/( 232 Th series) and 230 Th ( 238 U series) found in the spring water samples is the main evidence for the existence of significant radioactive disequilibrium in both the radioactive series.
