Radon Measurement

A cancer-inducing, radioactive gas, radon can't be seen and has no scent or taste. The U.S. Surgeon General cautions that radon is among the leading causes of lung cancer in the country today - and our region's levels are above average compared to the rest of the US.

Radon Measurement

A cancer-inducing, radioactive gas, radon can't be seen and has no scent or taste. The U.S. Surgeon General cautions that radon is among the leading causes of lung cancer in the country today - and our region's levels are above average compared to the rest of the US.

No Scent, No Taste, No Color Discovered by physicists in 1900, radon is a colorless, inert gas that can easily penetrate common materials - from paper, leather and plastic bags to most paints and building materials. It's a natural radioactive gas originating from the natural degradation of uranium, typically discovered in rock and soil, and sometimes naturally occurring in well water too. If you are a smoker and your home or workplace contains high radon levels, you're possibly at heightened risk. Because they tend to have a higher respiration rate, younger people may be more susceptible to health problems stemming from radon.

A Nationwide Health Issue

Radon is a nationwide environmental health issue, with elevated radon levels identified in all states. According to the Environmental Protection Agency, up to eight million homes throughout the country have increased levels of radon. In commercial locations and workplaces, people in confined air spaces are generally in contact with elevated levels of radon.

Radon in the Midwest

Radon levels within our geographical service area are classified as above average compared to the rest of the US. Most counties in our region are EPA Zone 1 - predicted to have potential elevated indoor radon levels above 4.0 pCi/L - with the remainder in Zone 2 (2–4 pCi/L). There are no Zone 3 counties within our region. These guidelines alone can't determine actual radon levels in an individual home - an actual radon test should be conducted - but we can conclude that our service region is an elevated potential area where testing is recommended.

The Importance of Radon Testing

Radon testing is the only reliable way to know radon levels in your home or commercial building. There aren't any sudden, obvious symptoms that may warn you of the presence of radon, and it may require years of exposure before complications surface. The Surgeon General, American Lung Association and American Medical Association all advise radon testing because it's the best and only method for accurate detection. We use professional continuous radon monitors over a minimum 48-hour test period, delivering a clear report of your home's levels.
