Vol. 55, No. 4

573-577

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 Bqźm–3 were found at three points close to the summit, at altitudes of about 3000 m above the sea level, and in the range of 3.0–19.6 Bqźm–3 elsewhere. An average radon concentration of 7.9 Bqźm–3 was obtained in the northern region, 4.8 Bqźm–3 in the eastern (oriented towards the sea), 9.6 Bqźm–3 in the western (the furthest inland), and 6.5 Bqźm–3 in the southern.
