What is Radon Gas?Almost every week we as Realtors deal with a particular inspection issue - Radon. A radioactive gas, radon comes from the natural decay of uranium that is found in the soil, rock & water. Radon typically moves up through the ground to the air above & into your home through cracks in solid floors & walls, gaps around service pipes & in suspended floors, construction joints & cavities inside walls. Your home's water supply can be a source of radon, but this usually is not a problem if your water source is from surface water not ground water. Your home traps radon inside, where it can build up. Radon is a health risk, and like other enviromental pollutants, there is some uncertainty about its magnitude.Buyers should test for Radon, and Sellers should understand that a repair request to install a radon mitigation system is valid.
