Radon (222Rn) activity concentration in outdoor air was measured, using AlphaGuard radon monitors, at 25 points in the Mt. Etna area, at different distances and in different directions from the summit. Values of up to 93 Bqm3 were found at three points close to the summit, at altitudes of about 3000 m above the sea level, and in the range of 3.019.6 Bqm3 elsewhere. An average radon concentration of 7.9 Bqm3 was obtained in the northern region, 4.8 Bqm3 in the eastern (oriented towards the sea), 9.6 Bqm3 in the western (the furthest inland), and 6.5 Bqm3 in the southern.
