Radon is the leading cause of lung cancer among non-smokers and the second leading cause of lung cancer overall.
Radon is an invisible, odorless radioactive gas that occurs naturally in soil and rock. It can enter buildings through cracks or gaps in the foundation. The only way to know if your home or business has radon is to test for it.
Each year approximately 21,000 lung cancer deaths are caused by radon.
Radon exposure can cause lung cancer in smokers and non-smokers.
Up to 40% of Pennsylvania homes have dangerous radon levels.
Radon levels of 4 pCi/L or higher require remediation.
