FAQ’s for Radon Mitigation in Peoria, Illinois and throughout Illinois.Kit Wilcox, Knoxville

What is Radon?

Radon is a naturally occurring colorless, tasteless, odorless gas that is produced from the decay of Uranium and Radium.
Where does Radon come from?
In central Illinois most of the Radon gas is produced from rocks deposited from glaciers. When the glaciers moved over Canada, rocks with high amounts of Uranium where transported in the glaciers. When the glaciers melted those rocks became part of our soil structure. (Radon Potential Map) [1]
Why is Radon gas harmful?
Radon gas breaks down very rapidly and produces radioactive particles. These radioactive particles can become trapped in the lungs and cause DNA damage which over a period of time can increase the chances of lung cancer.

How does radon enter a home?
Radon gas enters through cracks in the floor, cracks in relief cuts, open earth areas like crawlspaces and open sump pits. The reason radon gas enters, through the cracks and open earth areas, is ground gas pressure is greater than the pressure inside of the home due to air being removed by: clothes driers, furnaces, central vac systems, range hoods and whole house fans.   When the radon system installation is finished, radon levels will be dramatically reduced.
How can I determine if radon is a problem?
Radon testing in Illinois is the only way to determine if a home has high radon levels. A licensed radon measurement professional can test for these levels. For initial testing a home test kit can also be used.


What does a radon mitigation system cost?
In Illinois the state radon regulations requires a signed contract that includes the total cost of the radon system.
1)  For most homes the cost of a radon system can range between $850 – $2,200 depending on the foundation type, the number of different types of foundations, and the design of the home.
2) For commercial buildings and schools the cost is based on the scope of the project.
