DHS Encourages Homeowners, Property Owners, and Schools to Test for Radon

Radon, a colorless, odorless gas, can seep into homes through their foundation and be deadly at high levels. In Wisconsin, 1 in 10 homes has elevated levels. Radon is the second leading cause of lung cancer, and approximately 962 Wisconsinites have radon-induced lung cancer. Fortunately, radon is easy to test for and leaks can be fixed. This National Radon Action Month, the Wisconsin Department of Health Services (DHS) is encouraging home and building owners, and schools, to understand their risk and test their buildings for radon.

"Knowing about radon and testing radon levels in your home can save lives," said DHS State Health Officer Paula Tran. "In Wisconsin, we have 17 Radon Information Centers around the state where experts are available to answer your questions and offer low-cost test kits. Indoor radon levels tend to increase during the colder months, so now is the perfect time to test your home or building for radon if you haven't before."

While radon can affect anyone, children are generally considered to be more sensitive compared to adults due to their smaller lung sizes and faster breathing rates. Along with encouraging testing at home, Wisconsin continues to take steps to improve testing in spaces where children spend significant amounts of time. In March 2023, the Wisconsin Department of Children and Families (DCF) enacted rule changes which require licensed child care providers to test for radon and install a mitigation system if radon levels exceed the EPA action level. In addition, DHS recommends that all schools test for radon at least once every five years or upon completion of any major renovations.

"Since the DCF rule went into effect, 41 child care centers across Wisconsin have mitigated high radon, protecting over 820 children enrolled in care from exposure to high radon levels," said DHS State Health Officer Paula Tran. "Preventing exposure to high radon in places where kids spend a lot of time is a significant way to reduce their overall exposure to radon."

Reduced-cost test kits are available to child care providers and all Wisconsin residents through their regional Radon Information Center and test kit promotions are happening throughout January. The cost of mitigation can be a barrier for some families and businesses; Wisconsin residents can visit their Radon Information Center or speak with local public health department radon experts by calling 888 LOW-RADON to discuss available options.

Any house or building can be at risk for high radon levels, including apartments and commercial buildings. Landlords have a responsibility to provide safe living and working conditions to their tenants and should work with a certified radon testing or mitigation contractor to get started on addressing the issue for their tenants. DHS encourages homeowners and property owners to use a certified contractor and to locate one using resources available on the DHS How to Find a Contractor webpage.
