Radon is an odorless, invisible radioactive gas. It’s naturally released from rocks, soil and water — and it can enter your home. Breathing high levels over time can lead to lung cancer. In fact, radon is a Class A carcinogen. It’s the No. 1 cause of lung cancer in nonsmokers and the second-leading cause of lung cancer overall. Radon can be found in any home — old or new — and typically enters through cracks in the foundation caused by natural settling. Radon levels often are higher in lower levels and basements. Testing is the only way to determine the radon level in your home.
The EPA recommends four picocuries per liter of air (4 (pCi/L) or less.
If your home tests higher than 4 pCi/L, then you’ll need to have a professional address the radon issue, which includes installing venting equipment. Once the mitigation system has been installed, your home should be tested again to make sure the issue has been resolved.
