Title: | Radioactivity content in volcanic rocks and radionuclides transfer from rocks to groundwater at Mt. Etna volcano | Journal: | Annals of Geophysics | Series/Report no.: | 5/62 (2019) | Issue Date: | 2019 | DOI: | 10.4401/ag-7549 | Keywords: | Mt. Etna volcano Natural radioactivity Volcanic rocks Groundwater Radiological risk |
Subject Classification: | 05.09. Miscellaneous | Abstract: | The paper presents the results of a radiometric survey carried out on the eastern flank of Mt. Etna over an area of approximately 120 km2. Activity concentrations of 238,234U, 232,230,228Th, 226,228Ra, from 238U and 232Th decay chains, and potassium 40K were determined using α- and γ- spectrometry techniques. All rock samples presented activity concentrations of U, Th and Ra isotopes ranging from 20 Bq kg-1 to about 90 Bq kg-1, and they showed no particular compositional variations over the investigated area. Based on their respective elemental concentrations, the isotopic ratios of different elements were studied to check the presence of radioactive equilibrium, or disequilibrium, in the decay chains. Moreover, an attempt to calculate radionuclide transfer factors from soil to water was made, and the radiological risk resulting from ingestion of these isotopes contained in drinking water was calculated. The results were compared with current regulations on the quality of drinking water. |
