Description:
Radioactivity in underground waters from Mt. Etna was investigated on the basis of 13 samples. The
samples were collected from springs, wells and galleries around the volcano. Water from nine out of
thirteen intakes is used for consumption. Activity concentration of uranium isotopes 234,238U, radium
isotopes 226,228Ra and radon 222Rn were determined with the use different nuclear spectrometry techniques.
The measurements of radium and radon activity concentration were performed with the use of
a liquid scintillation counter. The determination of uranium isotopes was carried out with the use of
alpha spectrometry. All samples show uranium concentration above Minimum Detectable Activity
(MDA), with the highest total uranium (234U þ 238U) activity concentration equal to 130 mBq/l. For
radium isotopes, all samples except one showed the activity concentration below MDA. Radon activity
concentration was within the range from 1 to 13 Bq/l, hence these waters can be classified as low-radon
waters.
