Overview of Radon and its Health Implications

Radon is a radioactive gas occurring naturally in the ground beneath us and can enter indoor spaces. It is a silent killer since it has no odor and can be dangerous. It is necessary to take measures to prevent radon exposure to ensure the safety of ourselves and our loved ones.

The Wisconsin Department of Health Services estimates in some areas of Waukesha County, Washington County, and Dodge County, the number of homes with radon levels above EPA guidelines on the main floor could be as high as 60%!

Radon is a harmful gas that can take years to manifest its effects, but once it does, it can lead to serious health problems. Prioritizing testing in residential and commercial spaces is crucial to detect high radon levels. Ensuring the safety of individuals in these spaces should be a top concern.


Average Radon Levels in Wisconsin

Did you know Wisconsin has an estimated mean radon level of 5.7 pCi/L, slightly higher than the national average of 1.3 pCi/L? That's right, almost 1 out of every 9 homes in Wisconsin may have higher radon levels than the Environmental Protection Agency's recommended level!

And get this - nearly two-thirds of the state's counties fall under zone 1, which means there's a more significant potential for elevated indoor radon levels.

The radon zone map was created in 1993 to provide information on the potential level of radon gas in a given area. It's important to understand that the level of exposure and risk to your health may vary depending on your zone. Unfortunately, there is no way to determine the radon level in your indoor space without testing, so it's wise to consider professional testing to minimize potential risks.


Zone 3

Radon zone 3 has a low potential for elevated radon levels, with average indoor levels typically measuring less than 2 pCi/L. However, it's important to note that Wisconsin has higher radon levels and therefore does not have a zone 3 designation. This means that residents of Wisconsin should take extra precautions to test their homes for radon and implement mitigation strategies if necessary.


Zone 2

If the radon level in Zone 2 is detected, it signifies a moderate potential for radon exposure. The average indoor radon levels may range between 2 and 4 pCi/L during testing. It is crucial to take necessary precautions and measures to reduce radon levels to ensure a safe indoor environment.


Here are the areas in Wisconsin that come under Zone 2-


Douglas Bayfield Ashland Iron Vilas

Zone 1

Regarding radon levels in indoor spaces, Zone 1 indicates the region with the highest potential for elevated levels of radon gas. It means that the average indoor radon levels in this area may be greater than 4 pCi/L (picocuries per liter), which is a level that requires action to be taken to reduce the risk of health effects associated with prolonged exposure to radon gas.
