What is the minimum height or side distance for a radon mitigation system exhaust termination from an operable window?

For a radon mitigation system, the minimum distance from an operable window to the exhaust termination is set at 2 feet. This requirement helps ensure that any radon gas expelled from the system does not easily re-enter the building through open windows, where occupants could be exposed to potential radon exposure.

The 2-foot distance is based on understanding air movement and the dispersion of gases, ensuring that there is adequate separation between the exhaust and any potential points of re-entry into the living space. This distance also considers wind patterns and building design, as it helps mitigate the risk of recirculation of exhaust gases back into the home.

Maintaining this minimum height promotes safety in residential environments by aligning with recommended practices outlined in radon mitigation standards. It reflects a commitment to reducing indoor radon levels effectively while prioritizing occupant health and compliance with industry guidelines.
