Description:
The report gives results of a study of eight houses throughout their construction in. orth Central Florida. ach house was built in compliance with the proposed radon resistant construction standard being developed by the Florida Department of Community Affairs. ach house was monitored for at least 6 days after construction, operating in three different heating, ventilation, and air-conditioning (HVAC) system configurations. ontinuous measurements of indoor radon concentrations, house ventilation rates, across-slab differential pressures, and interzone differential pressures provided time-resolved radon entry rates and a performance index for passive radon barriers. adon entry rates were found to be relatively constant throughout the measurement periods and for the different house operating conditions, implying that the passive radon barrier eliminates most convective entry. he passive barriers maintained radon entry fluxes at < 1.2 pCi /sq m/ sec for subslab radon concentrations as high as 9,500 pCi/L. he study results show that the operation of well designed and constructed HVAC systems does not significantly affect indoor radon concentrations, regardless of the pressures induced between interior air zones.
