De Pere, WI - February 12th, 2026 - Brown County officials launched a crucial public health initiative Tuesday, aiming to safeguard residents from the dangers of radon gas exposure. The program, offering free radon test kits, comes as mounting evidence reveals elevated radon levels not just in Brown County, but across the state of Wisconsin. While often overlooked, radon represents a significant - and preventable - health risk, being the second leading cause of lung cancer in the United States.

Radon is a naturally occurring, radioactive gas produced by the breakdown of uranium in soil, rock, and water. It's a colorless, odorless, and tasteless gas, making it impossible to detect without specialized testing. This insidious nature is precisely why the Brown County Health Department is emphasizing the importance of proactive testing.

"We're seeing elevated levels of radon in Brown County and throughout Wisconsin," explained Susan Weber, Director of the Brown County Health Department. "This program is about providing residents with an easy and affordable way to test their homes and take action if necessary. It's not something to be ignored; it's a serious public health concern."

Why is Radon a Concern?

Radon enters homes through cracks and other pathways in foundations. Its radioactive particles can become trapped in the lungs when inhaled, increasing the risk of lung cancer over time. The EPA estimates that approximately 21,000 lung cancer deaths each year are radon-related. Smokers are at an even higher risk, as radon exposure significantly amplifies the dangers associated with cigarette smoking. The U.S. Environmental Protection Agency (EPA) recommends that action be taken to reduce radon levels if a home tests at or above 4 picocuries per liter (pCi/L).

Wisconsin and Radon: A Particularly High-Risk State

Wisconsin, due to its glacial history and geological composition, is unfortunately considered a high-radon state. The state's unique soil composition and prevalence of bedrock containing uranium contribute to higher than average radon levels. This means a larger percentage of homes in Wisconsin are likely to have elevated radon levels compared to many other states.

The Wisconsin Department of Health Services (DHS) has long been at the forefront of radon awareness and mitigation efforts. The current funding for Brown County's program originates from a grant awarded by the DHS, demonstrating the state's commitment to addressing this public health challenge. More information on statewide radon levels and resources can be found on the DHS website.

How the Brown County Program Works

The Brown County Health Department is currently distributing free radon test kits to residents while supplies last. Kits can be picked up at the Health Department itself, as well as at various community locations throughout the county, including local libraries and select community centers. The kits are simple to use, requiring residents to place the testing device in their basement or lowest level for a specified period - typically a few days - before mailing it to a certified laboratory for analysis.

"It's really important for everyone to test their homes, even if they think they're safe," Weber added. "Radon is odorless and colorless, so you can't see or smell it. The only way to know if you have a problem is to test."

What if Elevated Levels are Detected?

If a home tests at or above 4 pCi/L, the EPA recommends taking steps to reduce radon levels. Radon mitigation systems, installed by certified professionals, can effectively reduce radon concentrations by venting the gas from beneath the foundation and safely releasing it outdoors. While the cost of mitigation can vary, it's a relatively affordable investment considering the potential health benefits. Numerous resources are available to help homeowners find qualified mitigation contractors.

Beyond Testing: Long-Term Radon Awareness

The Brown County Health Department hopes this program will not only address current radon levels but also foster a culture of long-term radon awareness. They encourage residents to retest their homes every few years, as radon levels can fluctuate due to changes in weather patterns, construction, or landscaping. The department also plans to conduct public awareness campaigns to educate residents about radon risks and mitigation strategies.
