Indoor air concentrations of radon and radon short-lived decay products, equilibrium factor, unattached fraction of radon short-lived decay products (fun), relative humidity and temperature have been measured in Slovenian schools, with an emphasis on fun as the crucial parameter in dose assessment. fun ranged from 0.03 to 0.21. Dose conversion factors, based on these values, exceeded 5 mSv/WLM, the value recommended by ICRP-65, in all schools.


Key words: radon unattached fraction, dose conversion factors
