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. For more information check online at www.epa.gov/radon and other sources.

Radon is a odorless, colorless, tasteless radioactive gas derived from the naturally-occurring decay of other radioactive materials found under the earth's surface.  Some estimates put 1 out of every 15 homes have some sort of "elevated" radon levels. EPA and others in the scientific community haven't agreed upon a safe-level or threshold for radon levels--latest guideline that I know of suggest that if radon level is 4+ pCi/L, you may want to take action/investigate. Mitigation systems are available. If you suspect radon or have concerns regarding a property and potential for overexposure, radon testing services and kits are available.

Luckily I am in an area free of the worry of radon. In the last 12 years here I have not done or had a radon test. Being oceanfront on a sand bar has some good things I guess and since we have no basements there is little to no worry about radon.
