Radon is found throughout Wisconsin.
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.
Soil and geology impacts how radon moves
The soil under and around a house is usually the source of indoor radon. Uranium naturally exists in soil and bedrock, and radon is created when uranium decays. Radon can travel through air pockets in the soil and into your house.
House construction impacts radon's ability to enter homes
House construction (openings to soil) is another variable factor of indoor radon. Radon can enter the home through cracks in the foundation. Learn how to reduce the level of radon in your home and get your home tested!
