January is National Radon Action Month

If you’re not familiar with radon, the Wisconsin Department of Health Services (DHS) states that radon is the second leading cause of lung cancer in the United States, and describes it as, “a naturally occurring gas that is radioactive and can cause lung cancer.”

What is Radon?

“Radon is a radioactive gas that is found across the state of Wisconsin and travels only a meter or two through soil from where it was created. Radon comes naturally from uranium through a long series of radioactive transformations, meaning it undergoes radium decay before it is transformed into a chemically reactive atom.

Radon enters basements as the air tends to be at lower pressure than the soil gases under the slab. Cracks and openings in basements allow the radon to enter the home.” – Wisconsin DHS Radon website.

The DHS notes that about one out of 10 homes in Wisconsin have high radon levels.  You can’t see or smell radon. Testing is the only way to know your level of exposure, and can have a big impact on your indoor air quality.

You can buy a radon test kit from a hardware store or a Radon Information Center for approximately $20.  More information on testing your home for radon may be found here.
