Radon Gas

Radon is a known carcinogen. The lower the level of radon inside your home, the lower your family’s risk of developing lung cancer from it. Radon gas is everywhere, even in the fresh air we breathe outdoors.


In 1988, Congress enacted the Indoor Radon Abatement Act. With the natural outdoor level of radon being established in the act at 0.4 pCi/L, the target radon level for indoor air should be the same or lower.
