Radon in The Upper Midwest: What You Need to Know

Radon naturally occurs from the breakdown of uranium in the soil. It’s colorless and odorless and can seep into homes undetected, increasing the risk of lung cancer for those who are regularly exposed to it.

The EPA estimates that nearly one in every 15 homes in the United States has elevated radon levels. However, the prevalence of radon gas in the Upper Midwest is considerably higher than the rest of the country. This is due to the region’s unique geological makeup, which has higher concentrations of uranium in the soil.

In Minnesota, which is part of the Upper Midwest, over 40% of homes have elevated radon levels. Wisconsin also has a high prevalence of radon gas, with around 42% of homes exceeding the EPA’s recommended action level of 4 pCi/L (picocuries per liter). However, it’s worth noting that there’s no specific threshold for safe radon exposure, and even low levels of exposure may pose a health risk.

It’s important to note that radon levels can vary widely from home to home, even within the same neighborhood. Factors that may affect radon levels include the home’s construction, the local geology, and seasonal changes in soil moisture. Therefore, it’s critical that homes be tested for radon so that appropriate remediation measures can be taken.
