One in four Michigan Homes has high levels of radon - graphicSome counties are known to have a higher likelihood of having homes with elevated radon.  Check out the map below to see if homes in your county typically have elevated radon levels. Keep in mind that homes in counties with a lower likelihood of having high radon levels should still be tested. 

While your neighbor's test results may give you an idea of the potential for a problem in your home, radon levels can vary significantly from lot to lot and home to home.  Do not rely on your neighbor's test results to determine your risk.  Test your own home and be certain!  Find additional details on county radon levels on-line at http://mi-radon.info/MI_counties.html
