Indoor radon monitoring in Zázrivá

Abstract

Indoor radon survey in Zázrivá was conducted within the framework of the project “Multidisciplinary research of geophysical and structural parameters, and environmental impacts of faults of the Western Carpathians”. Monitoring was carried out in selected houses and kindergarten using RamaRn detectors. Annual average of indoor radon varied between 45 and 260 Bq/m3, with median of 90 Bq/m3. Seasonal variation with minimum in summer was observed in the majority of monitored rooms. Radon concentration higher than 200 Bq/m3 was measured only in rooms with direct contact with the subsoil. A possible relation between the position of a monitored building close to an assumed fault line and elevated indoor radon levels was not proven.
