What is radon, in one sentence?
A colorless, odorless radioactive gas from uranium in the ground that can build up inside houses.
Why should I care?
Wisconsin DHS calls radon the second leading cause of lung cancer in the U.S. and the leading cause among people who have never smoked.
Is River Falls a high-radon area?
Statewide, Wisconsin DHS says about 1 in 10 homes test high. Neighboring houses can differ a lot, so a local average doesn't tell you about yours.
What result means I should act?
Wisconsin DHS treats levels above 4 pCi/L as high. EPA also suggests considering a fix between 2 and 4.
Do I need a Minnesota-licensed contractor?
Not for a Wisconsin house. Wisconsin has no license requirement. DHS recommends NRPP or NRSB certification.
Does selling a house in River Falls require a radon test?
No. Wisconsin doesn't require radon testing or disclosure in a sale, but DHS highly recommends testing. Minnesota's disclosure rules don't apply to Wisconsin property.
My house has a radon pipe but no fan. Is that enough?
It's a passive system. Test the house. If the level is high, a contractor can usually add a fan.
