A program of measurements in and outside the plume of Etna volcano has shown that radon daughters (as well as gaseous radon) are directly emitted from the magma. Enrichment factors have been observed : 4 for bismuth vs lead and 6 for polonium vs lead. The 210 Pb total output measured for the Etna plume is an insignificant source for this nuclide.
