نبذة شخصية:	In a house with forced air heating and cooling, radon gas can conveniently be distributed throughout the entire home. When radon gas is released via a radon reduction system over the roofing, the radon focus falls off significantly with distance from the point of discharge. In fact, the radon gas concentration approaches background degrees at 3-4 feet from the discharge point. EPA refused ground degree discharge of radon primarily as a result of the potential for re-entrainment of the gas right into your home and because of the opportunity of kids being revealed to high radon levels. The focus of radon gas at the discharge point can be 10s of thousands of picocuries per minute.
