Why Is Radon Vented Above My Roof?

Radon is about 7.5 times heavier than air. It’s easily influenced by air movements and pressure. In a house with forced air heating and cooling, radon can easily be distributed throughout the entire structure. When radon gas is discharged via a radon mitigation system above the roof, the radon concentration falls off dramatically with distance from the point of discharge. In fact, the radon gas concentration approaches background levels at 3-4 feet from the discharge point. The Environmental Protection Agency disallowed ground level discharge of radon primarily because of the potential for re-entrainment of the gas into the house and because of the possibility of children being exposed to high radon levels. The concentration of radon gas at the discharge point can be tens of thousands of picocuries per minute.
