The leading cause of lung cancer in non-smokers.

Lung cancer is not immediately noticeable. You may be exposed to radon for years without ever suspecting its presence.



Radon is a colorless, odorless radioactive gas.

The IEMA recommends measuring your indoor radon concentrations every two years. Schedule an appointment today.

Home – About Us

DuPage Radon Testing, Inc. is a Warrenville based radon measurement company servicing the Chicago suburbs. Established in 1998, we provide short-term residential radon screenings using femto-TECH continuous radon monitors and Rad Elec E-PERM® chambers. Both devices allow us to generate a formal result report the same day the test is completed, making us ideally suited for use in real estate transactions where time is of the essence. A hard copy of the report is mailed to the client. Electronic copies are available to be faxed or e-mailed for faster distribution.

 There is NO safe level of Radon Gas. Any reading that is NOT below 4.0 pCi/L needs to be remidated.

If you are considering buying a house in Illinois, you should have the home tested to determine the level of radon gas in the home.  In addition to when you first buy a home, it is highly recommended  you have your home re-tested every two years to make sure the levels have not changed.  Radon levels change all the time – your home could pass a test at purchase and fail a year or two later.  Just like your home could have radon, and your neighbor’s home may not.  Help keep your family safe  - get your home tested today.
