摘要

The paper presents the results of a radiometric survey carried out on the eastern ank of Mt. Etna over an area of approximately 120 km 2 . Activity concentrations of 238,234 U, 232,230,228 Th, 226,228 Ra, from 238 U and 232 Th decay chains, and potassium 40 K 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 concen- trations, 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
