“…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.

Abstract. Introduction. Drinking waters usually contain several natural radionuclides: tritium, radon, radium, uranium isotopes, etc. Their concentrations vary widely since they depend on the nature of the aquifer, namely, the prevailing lithology and whether there is air in it or not. Aims. In this work a broad overview of the radioactivity in drinking water is presented: national and international regulations, for limiting the presence of radioactivity in waters intended for human consumption; results of extensive campaigns for monitoring radioactivity in drinking waters, including mineral bottled waters, carried out throughout the world in recent years; a draft of guidelines for the planning of campaigns to measure radioactivity in drinking water proposed by the Environmental Protection Agency (ARPA) of Lombardia.Key words: radioactivity, drinking water, water quality, public health. Riassunto (Radioattività nell'acqua potabile: le normative, i risultati dei monitoraggi e i problemi di radioprotezione).Introduzione. L'acqua potabile contiene normalmente molti radionuclidi naturali: trizio, radon, isotopi del radio e dell'uranio, ecc. La loro concentrazione è molto variabile perché dipende dalla natura dell'acquifero, dalla presenza di aria in esso e dalla litologia prevalente. Scopi. In questo lavoro è presentata un'ampia rassegna sul tema della radioattività nelle acque potabili: le norme nazionali e internazionali per limitare la presenza di radioattività nell'acqua destinata al consumo umano; i risultati di estese campagne di monitoraggio nelle acque potabili, comprese le acque minerali imbottigliate, condotte nel mondo negli ultimi anni; una proposta di linea guida per la pianificazione di campagne di misura della radioattività nell'acqua potabile elaborata dall'Agenzia Regionale di Protezione Ambientale (ARPA) della Lombardia.Parole chiave: radioattività, acqua potabile, qualità dell'acqua, sanità pubblica.

“…226 Ra and 222 Rn are the main radionuclides generally observed in natural waters, occurring in highly variable concentrations constrained mainly by geological factors [75]. Moreover, it is well known that 222 Rn has a strong affinity to Non-Aqueous Phase Liquids (NAPLs) and can be used as a tracer to detect these substances (e.g., [76,77]).…”

Environmental Groundwater Vulnerability Assessment in Urban Water Mines (Porto, NW Portugal)

A multidisciplinary approach was developed to estimate urban groundwater vulnerability to contamination combining hydrogeology, hydrogeochemistry, subterranean hydrogeotechnics, groundwater ecotoxicology and isotope tracers. Paranhos and Salgueiros spring waters in Porto City were used as a case study. Historical and current vulnerability scenarios were compared using hydrogeological GIS-based modelling. Potential contamination sources were mapped around the spring galleries. Most of these were point sources and their potential contamination load was moderate. The ecotoxicological assessment indicated a low acute toxicity potential. Groundwater radionuclides appeared to be mainly controlled by geological factors and biomineralisation. Vulnerability maps suggest that most of the area has a moderate to low vulnerability to contamination. However, some surface sources such as sewage systems cause contamination and contribute to increased vulnerability. This integrated approach was demonstrated to be adequate for a better knowledge of urban hydrogeological processes and their dynamics, and highlighted the importance of a vulnerability assessment in urban areas.
