Radon is a well known radionuclide in the field of volcanology, being its emanation from soil and fumaroles largely studied. We report an attempt to measure radon concentrations in the main plume arising directly from the degassing magma body at the Mt. Etna volcano, without interactions with soil and/or hydrothermal systems, by means of both active and passive detectors. Short-lived radon daughters (218Po, 214Pb, 214Bi, 214Po) concentrations are also measured, together with the gamma noise arising from cosmic rays and ground emitters from the crater rim. The obtained results encourage us to improve and further validate our methodologies in the next future.
