Radon Testing for Daycare Facilities

Beginning Jan. 1, 2014, All day care centers will need to show proof the facility has been tested for radon within the last three years as part of the initial application or license renewal process. 

Radon is a colorless, odorless, tasteless radioactive gas that comes from the radioactive decay of naturally occurring   uranium in the soil.  It’s estimated that nearly 1,200 radon-related lung cancer deaths occur each year in Illinois.

Cottages to Castles can help daycares meet this new requirement


We hold the necessary Professional License credentials required by the State of Illinois to conduct radon testing for Commercial buildings including Daycare centers. Radon testers must hold a Professional License with the State of Illinois, Those licensed to test radon in residential real estate transactions may not be licensed to test daycare centers.

 Is it required to be tested for radon?

 Yes, all daycares licensed by the State of Illinois are required to be tested for radon, although home daycares have an option of doing the testing themselves. All other state-licensed daycares are required to hire licensed professionals.

How long is required to setup and conduct the test?

A few minutes are required to set up each testing device, and the layout of the building will determine how many devices are needed. The test in normally 48hrs if closed building condition are met 12 hours prior to test. Arrangements can be made to set up and pickup the devices before or after normal business hours.

How much will the radon testing cost?

The costs can vary depending on the number of rooms required to be tested with the size of the facility. Home Daycare centers start as low as $225 which varies on the size of the home and what areas are being used as the Daycare.

What if I find out the radon levels are high in my daycare?

 The law does not require day care facilities to reduce radon levels if they exceed the U.S. Environmental Protection Agency’s action level of 4.0 pCi/L.  IEMA recommends radon reduction actions be taken if radon levels are above 4.0 pCi/L and licenses contractors who install radon mitigation systems. We can provide a list of state-licensed radon mitigators in the event you would consider mitigating.
