Radon Information for Wisconsin

Radon is a naturally occurring, odorless radioactive gas that causes lung cancer. Between five and ten percent of the homes in Wisconsin have radon levels above the US EPA guideline of 4 pCi/L for the year average on the main floor. Every region of Wisconsin has some homes with elevated radon levels.
The only way to know the radon level in a house is to measure it. You can get Radon test kits in hardware stores or from local health agencies (see information centers, below) for around $20. Radon can be controlled in any house.
