Radon in Illinois
According to the U.S. EPA, one in every 15 homes in the United States have radon levels that exceed the recommended radon action level. In Illinois between 2003 and 2007, 42% of homes tested for radon gas had levels above the EPA radon action level.
|The following data was compiled by the Illinois Emergency Management Agency (IEMA) Radon Program for homes tested between 2003 and 2007:|
| KEY: Blue – Zone 1 – High potential Yellow – Zone 2 – Moderate Green – Zone 3 – Low potential |
Note: This map is not intended to determine if a home in a given zone should be tested for radon. Homes with elevated radon have been found in all three zones. All homes should be tested regardless of geographic location. It is recommended that homes are tested every two years.
