Emission and enrichments of radon daughters from Etna volcano magma

Résumé

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 210pb total output measured for the Etna plume is an insignificant source for this nuclide. Procedures During June 1976 aerosol was collected on filters at various locations near the Etna volalso ß Universit• de Picardie, also ß Terres Australes et Antarctiques Fran•aises.
