Radon Testing
Radon is a radioactive, odorless, colorless gas formed by the decay of radium that occurs in soil, water and natural gas. The U.S. Surgeon General has listed radon as the number two cause of lung cancer, and it accounts for about 20,000 deaths annually.
Radon usually enters the house through a crawl space or slab on grade floor or cracks and joints in foundations. Home centers sell home radon testing kits to find out if you have a problem. But a professional analysis of radon levels can better pinpoint your problem.
Radon levels can be reduced by sealing cracks in basement walls or floors, or by properly ventilating a crawl space. If that doesn't work, a Service Professional can install a venting system that pulls radon out of the basement or crawl space and discharges it into the air.
