​Radon is a colorless, odorless, radioactive gas that occurs naturally from the breakdown of uranium. Rocks and soil can contain uranium. Radon gas can enter through cracks in homes/buildings/schools and expose people to radiation.

Radon is the second leading cause of lung cancer in the United States. The United States Environmental Protection Agency (US EPA) estimates that 21,000 yearly lung cancer U.S. deaths are associated with radon.​​

The only way to know that radon is in your home is to test for it.

Radon Data in Kane County:

According to the 2006 Status Report for Radon in Illinois, 36% of the homes in Illinois are above the US EPA Action Level. If a home/building/school tests at 4 pCi/L or higher, action needs to be taken to remove the radon.

The average indoor radon levels of Kane County, as determined by radon test results from Air Check, Inc, is 5 pCi/L.

Radon-Resistant New Construction Policies (RRNC):

RRNC policies are relatively minor, low-cost, construction techniques that help reduce the radon levels in new homes that are built.

Effective June 1, 2013 all new residential construction in this State shall include passive radon resistant construction. Read the law.

Many Kane County builders have been educated about radon and have already adopted these policies. Since 1994 more than 1/3 of new homes built in Kane County have been built using Radon-resistant techniques.

Steps on the Best Practices for Child Care Centers & Parents
​The state legislature enacted a law requiring all licensed day care centers and homes to be tested for radon during license renewal: Public Act 097-0981 Radon Testing.

The Kane County Healthy Places Coalition has created a tool kit to make it easy for child care centers and homes to encourage parents to test their homes. The Child Care Radon Testing Photo Journal Tool Kit provides a quick guide to the various action items that child care centers and homes can choose from the tool kit to promote radon awareness among parents. We hope this tool kit helps many families with children in child care settings in Kane County.

The EPA Indoor Air Quality Tools for Schools provides schools with guidance, strategies, a list of frequently asked questions, and improvement plans to improve school air quality at little or no cost.


Secondhand smoke causes approximately 3,000 lung cancer deaths annually;​ radon causes 21,000. Doctors are in a position to educate their patients about testing procedures and methods for correcting elevated indoor radon levels. Most doctors ask their patients if they are a smoker or are exposed to second hand smoke but do not ask their patients if they have tested their homes for radon. Doctor involvement is crucial in reducing the incidence of lung cancer.
