Radon gas is a naturally occurring radioactive element that seeps up from the ground and can accumulate in your home, especially in basements and lower floors. It's the second leading cause of lung cancer after smoking, but it's invisible and odorless. Testing your home is the only way to know if you have a problem, and mitigation systems can effectively reduce high levels.
