Put simply, Radon is a naturally occurring radioactive gas that causes lung cancer. It is colorless, odorless, and tasteless. Undetectable by the human senses. It occurs due to a natural process called radioactive decay. Radon gives off tiny radioactive particles that can be breathed in. If the home isn’t adequately ventilated, you could experience prolonged exposure to Radon, which can cause lung cancer. Lung cancer caused by Radon has been reported to claim the lives of over 20,000 per year. Now just because your home has elevated levels of Radon, doesn’t mean you have to move, or that you shouldn’t buy that house. Although, those are decision best left up to you and your family. But it does mean there are some extra measures you should take to protect your family, if you do choose to stay or to buy the home.

We always recommend a Radon test, because it exists literally everywhere. But if you are looking at a home or are living in a county with a Radon Zone 1, we HIGHLY recommended that you get the Radon test. A level of 4 pCi/L or more would require a Radon Mitigation system to help protect your family.
