Cook County Illinois Radon Inspections
A common misconception is that the presence of high levels of radon gases found in homes only occurs in rural areas. This is not exactly true, but it is help supported by the fact that radon gasses are unlikely to reach unsafe levels in the majority of homes in midrise and highrise buildings common throughout urban areas of Illinois such as Chicago.
Breaches, cracks and gaps in the foundation of homes make ground-floor level homes (including houses, townhouses, garden level condos and homes with basements) more susceptible to higher levels of radon exposure that may warrant a radon inspection to ensure safety.
The EPA has identified Cook County Illinois as a Zone 2 county with expected levels of radon gas in an average home to be between 2.0 -4.0 pCi/L, which is considerate a moderate risk to health. Several cities in Cook County have been identified with high levels of radon expected in the average home to exceed 4.0 pCi/L on average – particularly in the southwest and northwest suburbs.
If you are concerned that a home that you may be buying, selling or living in Cook County or the surrounding area may have high levels of radon exposure, call Chicago Home Inspection Services at 773-510-7138 to schedule a radon inspection.
