Why Radon Testing Matters
Radon is a naturally occurring radioactive gas that can enter homes through cracks and openings in the foundation. You can't see it or smell it, but long-term exposure increases the risk of lung cancer.
In Pennsylvania, approximately 40% of homes tested have radon levels above the EPA's action level.
Radon levels can vary greatly between neighboring homes. The only way to know your home's radon level is to test.
