Radon testing & tips
 Radon is an odorless and colorless gas that naturally occurs in rock and soil. It can seep into homes from the soil through cracks in the basement floors and foundations, crawl spaces, poorly sealed sump pumps, porous cinder block walls and other foundation floor and wall penetrations. You can take immediate steps to reduce the amount of radon in your home:

• Fill or seal any cracks, crevices or holes in the foundation
• Provide a gas-tight cap for the sump pit
• Maintain a water level in trapped floor drains

The Illinois Emergency Management Agency has conducted a statewide screening for indoor radon, and has published annual data on radon levels by county and zip code since 2003.  Click here to view the IEMA data.

The Lake County Health Department encourages Lake County residents to check the radon levels of their homes or apartments. The Department sells short-term test kits, and many area hardware and building supply stores also have test kits available.  For more information on purchasing a kit, call 847.377.8020.
