ABSTRACT:
A radon removal system includes a packed mass transfer material aeration column and is sized to fit within a single story of a residential building. A residential water supply that is naturally contaminated with radioactive radon gas is connected to the top of the column. The water is preferably distributed across the top of the mass transfer packing by a coarse mist spray nozzle. The water splashes down through the packing and collects in a holding tank at the bottom of the column. Air, blown up through the column packing, comes into contact with the radon-laden water, and evaporates the radon out of the water. The radon-laden air is then vented outside the home.
