A passive radon mitigation system is a vent stack built into a new home that connects to a gravel bed below an airtight basement floor slab. This system depressurizes the gravel bed and vents to the outdoors. If severe radon problems are detected in the future, a ‘passive’ system can be converted to an ‘active’ system by adding an exhaust fan to the vent stack.
