The Environmental Protection Agency has designated January as National Radon Action Month. Radon is the second-leading cause of lung cancer in the United States, which results in 20,000 deaths annually. Risk for lung cancer is especially high for smokers exposed to high radon levels.
Radon is a radioactive gas that comes from the natural decay of uranium found in most soils. It typically moves up through the ground to the air and enters your home through cracks and other holes in the foundation. Your home traps radon inside, where it can build up. Any home—new or old—may have a radon problem. High radon levels have been found in every state.
Testing is the only way to know if you and your family are at risk. You can perform a test on your own or hire a radon test company. For homes or facilities found to have high radon levels, a qualified contractor should be consulted.
