“…Mean gross alpha and beta activities in the main course were found to be 0.095 and 0.21 Bq L −1 , respectively, being the main natural radionuclide contributions uranium, radium, and their alpha daughters for gross alpha activity, and 40 K and 226 Ra beta daughters for gross beta activity (Sanchez-Cabeza and Pujol 1998;Pujol and Sanchez-Cabeza 2000). The notable number of worldwide studies aimed at analyzing the levels of radioactivity in natural water bodies show a high variability of results, with gross alpha and beta activities ranging <0.008-0.782 and 0.021-0.816 Bq L −1 , respectively (i.e., Bozkurt et al 2007;Dueñas et al 2007;Forte et al 2007;Kücükömeroglu et al 2008;Popovic et al 2008;Selçuk Zorer et al 2009). The concentrations here reported for tap water from the Ebro River are generally in the lower range than those reported in the scientific literature.…”

This study was aimed at assessing the levels of 210Pb and 210Po concentrations as well as gross alpha and beta activities in environmental monitors from the Catalan stretch of the Ebro River (Spain), potentially influenced by the presence of sediments with high concentrations of 238U and its decay chain daughters in the Flix reservoir. The chronic daily intake of 210Pb and 210Po through ingestion and inhalation of soils was evaluated, and the derived non-carcinogenic and carcinogenic risks were characterized. The low concentration of radioisotopes in soils resulted in a negligible annual effective dose. The levels of 210Pb and 210Po were determined in various groups of highly consumed food (fish and seafood, vegetables, fruits, and rice), and their dietary intake was calculated. The annual effective dose for the adult people from food intake was estimated in 3.3×10(-2) mSv, mostly due to 210Po. Overall, the current radioactivity levels in the Catalan stretch of the Ebro River should not mean any additional health risk for the population living nearby. However, an integral assessment of the risks derived from exposure to other pollutants (e.g., metals and organochlorine compounds) jointly with radionuclides could be of great interest.
