Radon is a naturally occurring radioactive gas that seeps from degrading uranium in bedrock, soil and water. It enters our homes through basements and crawl spaces and accumulates. The only way to know whether or not you have radon in your home is to test for it.
Western North Carolina is a Zone 1 area, which indicates the highest potential for dangerous radon exposure, according to the EPA.
