Comparison of Effectiveness of Sub-Slab Ventilation Systems for Indoor Radon Mitigation: A Numerical Study; Comparaison a L`Aide D`Un Outil Numerique DE L`Efficacite Des Systemes DE Ventilation Active DU SOL Limitant La Penetration DU Radon Dans L`Habitat
Description:
The functioning of an active sub-slab ventilation system (SVS) has been studied successfully with the help of a previously evaluated numerical model. The parameters explored are the permeability of the sub-slab and the gravel placed beneath it, the amplitude of applied pressure at the installation point of the system and the functioning method: depressurization or pressurization. The mechanisms contributing to the success of the two systems are identified. This numerical study shows that the pr…
