The MN Department of Health recommends that all Minnesota homeowners test their homes for radon because it is widely believed to be the second leading cause of lung cancer. A radon test is the only way to find out how much radon is in your home. Hiring a licensed radon measurement professional is recommended when an unbiased, third party is needed, such as in a real estate transaction. The result from a properly performed radon test will help you decide if you need to reduce your home’s radon level.
The MN Department of Health estimates that 2 in 5 homes exceed the 4.0 pCi/L action level. The best way to know if you have a dangerous radon level in your home is to have a licensed professional test for it.
