Prevent Lung Cancer by Testing for Radon

Radon Leading Cause of Lung Cancer

Radon is the leading cause of lung cancer among non-smokers. When radon decays, the particles released are strong enough to pit plastic. More than 20,000 Americans die every year from radon.

Protect Yourself & Your Family

Simple steps can protect you and your family. Homes with high levels of radon can be fixed, and new homes can be built with radon-resistant new construction (RRNC) features.
