THE EFFECT OF RADON MITIGATION SYSTEMS ON VENTILATION IN BUILDINGS.

Author(s) : HARRJE D. T.

Summary

RADON MITIGATION CAN BE ACCOMPLISHED BY SOURCE REMOVAL AND EXCLUSION BY SEALING, LOCAL VENTILATION, AND DILUTION OF THE RADON GAS. AIR INFILTRATION RATES AND INTERZONE FLOWS HAVE BEEN MEASURED USING PERFLUOROCARBON TRACER TECHNIQUES IN RESEARCH HOUSES WITH RADON PROBLEMS IN WEST CENTRAL NEW JERSEY. USING A TYPICAL BASEMENT SUBSLAB DEPRESSURIZATION SYSTEM EMPLOYING A FAN TO LOWER THE PRESSURE IN THE GRAVEL AGGREGATE UNDER THE SLAB, SIGNIFICANT FLOW OF CONDITIONED SPACE AIR IS ENTRAINED INTO THE SYSTEM FROM THE BASEMENT. SINCE SUBSLAB DEPRESSURIZATION DEPENDS ON LOWERING SUBSLAB PRESSURES AT LEAST A FEW PASCALS, HVAC OPERATION IN THE BUILDING THAT LOWERS BASEMENT PRESSURES CAN INTERFERE WITH MITIGAE THESE VARIOUS PHENOMENA ARE DISCUSSED.
