Based on the measured activity concentrations of 226Ra, 232Th and 40K, radiological hazard indices, annual effective doses, as well as indoor radon concentration were determined. Calculated indoor radon concentration caused by investigated granite samples in 25% of cases exceeds the upper limit of 300 Bq m−3 recommended by the World Health Organization.
