    What You Need to Know About Radon

    Radon is a colorless, odorless, tasteless radioactive gas formed by the natural decay of uranium in soil. You cannot see or smell it, but it is a serious health risk.

    #1 Cause of Lung Cancer

    Among non-smokers, radon exposure is the leading cause of lung cancer, causing approximately 21,000 deaths annually in the US according to the EPA.

    1 in 15 US Homes

    Have radon levels at or above the EPA action level of 4 pCi/L. In Northern NJ (Zone 2), many individual homes test significantly higher.

    Completely Fixable

    High radon is a fixable problem. Professional mitigation systems can reduce radon levels by up to 99%, making your home safe again.
