Verification of seasonal correction factor for indoor radon concentration in Slovakia.

The results of a pilot study performed on data from selected dwellings in Slovakia suggested that the best agreement between measured and calculated annual mean indoor radon activity concentration (RAC) were obtained by using seasonal correction factors (SCF) determined for winter season. In this paper, SCF was applied on results obtained during a new, independent radon survey conducted in homes during years 2022–2023. In this study, 79 rooms were monitored throughout the year in four cycles based on 3 month indoor radon measurements. The preliminary results show a good agreement between measured and calculated annual mean RAC. [ABSTRACT FROM AUTHOR]
