Need a testing or mitigation company outside of Illinois? Try the National Radon Safety Board (NRSB) at our Links page.

Based on information contained in the National Academy of Sciences report, The Health Effects of Exposure to Indoor Radon, radon is estimated to cause between 15,000 and 22,000 lung cancer deaths per year.


Radon Is Easy To Detect And Reduce In A Home
The danger posed by radon can be detected rather easily through inexpensive do-it yourself testing, or through a trained radon contractor. Radon test kits can be purchased by mail order or in hardware stores and other retail outlets, your local health department may also supply test kits for a small fee.


Should the Company Performing Your Radon Test Also be Your Radon Reduction Contractor?
In Illinois it is illegal for the mitigation and testing company to do both the testing and repair of radon at the same home.  Ideally the company that performed the first test should do the retest after a mitigation system is installed, that way you have the same set of standard for both tests.

The EPA says: Be aware that there is potential conflict of interest if you use the same company to conduct both the test and the radon mitigation of the home. If the same radon testing professional also offers to do radon mitigation of the home, make sure that the testing is done according to the Testing Checklist.
