Radon is a colorless, odorless and tasteless gas that is produced by the decay of uranium and radium in the soil.
This gas is naturally occurring and can be found at various levels throughout Illinois and Grundy County.
The red areas indicate higher levels (above 4 pCi/L) of radon.
According to testing results provided by IEMA (Illinois Emergency Management Agency), 72 homes have been tested in
Grundy County and 44% had results above 4 pCI/L.

Radon rises through the soil and can enter buildings through small cracks in the foundation, gaps around pipes,
or sump pits. Generally, there is a negative pressure inside our homes which can cause an upward suction on
the soil gases.

Radon is the second leading cause of lung cancer. Non-smokers can be at risk of lung cancer from radon
exposure.

Radon is the greatest source of radiation exposure to the general public.
Testing is the only way to determine the radon level of your home. The Grundy County Health Department has radon test kits available for purchase. We will soon be able to offer radon measurement services as well.
We can also help with interpreting radon test results. Call us at (815)941-3115 if you have any questions regarding radon.

Test kits are $10 which includes the kit, shipping to the lab, and for analysis. Stop by our office at
the Grundy County Administration Building to pick up your kit!
