NE Illinois Radon Testing performs Professional Level Radon Testing for Concerned Homeowners and for those in Real Estate Transactions, through our license with the State of Illinois' IEMA/Division of Nuclear Safety.

Our service area includes Lake, McHenry, northern Cook and northern Kane counties in Northeastern Illinois.

Radon measurements are performed utilizing electronic monitoring devices, reporting in 1 hour intervals, for a minimum of 48 hours.  These short term tests may go longer than 48 hours, but not shorter than 48 hours. 

Education and understanding of radon is an important feature to our service.  We are always available for radon questions and referrals to information resources.

All homes have some level of Radon.   Radon can be an issue in all types of homes, including old and new homes, drafty homes, well insulated homes, homes with basements as well as those with crawlspaces and/or slabs.

The only way to know whether radon exists in elevated levels in the home you own, the home you rent or the home that you are purchasing is to TEST the home!


Everyone should test their home every two years, per the USEPA and IEMA/DNS.  Homes are dynamic, changing over time. Knowing your home's radon level is an important part of healthy indoor air quality for you and your family.

What is Radon?

Radon (Rn222) is a radioactive element that is part of the decay chain of naturally occuring uranium in soil.  Radon is a Class A known human carcinogen that causes lung cancer. 

Radon decay products attach to particles in the air which are inhaled and become lodged in lung tissue.  There they radiate and penetrate lung tissue which can initiate the process of carcinogenesis.


Smoking increases the risk of exposure to radon.

Radon emanates from soil, rock and water into the air we breathe.  Outdoors, the level of radon is diluted to a low (0.4 pCi/l) level.  However, indoors it can accumulate to higher levels.  The Action Level set by the US EPA is 4.0 pCi/l.  At this level or higher, it is recommended by the EPA and IEMA/DNS that the level be reduced with a radon mitigation system.

The EPA and other scientific organizations estimate that 21,000 lung cancer deaths per year are attributable to radon.

Because you cannot see, smell or taste radon, the only way to know your home's radon level is to perform a radon test.

The radon exposure compared to other radiation exposures is shown in this graphic provided by the US EPA.

Radon and thoron account for the singlemost form of radiation dose.
