Rezumat:

In the Harghita volcanic range (Romania) there are many occurrences of dry CO2 emanations, called mofettes. The emanating gas with high carbon dioxide content has a proved curative effect. The gas also contains important quantities of radon. Since the mofettes are used in curative purposes in several illnesses, in most of the cases without medical supervising, has been proposed to determine the radon activity concentration in some of the most frequented mofettes from Romania. The seasonal variations have also been monitored and were calculated the effective doses received by the patients during a cure. The radon activity concentrations’ levels above the mofettes indoor air range between 548 and 10 717 Bq/m3 while within the gas pools’ values between 3210 and 32 781 Bq/m3 have been measured. The effective dose received by the patients during a cure is between 0.0086 and 0.16 mSv. No major seasonal variations of the radon activity concentrations levels have been pointed out so far in the studied mofettes.
