Free Home Radon Test Kit 

We've had such a great response, we are currently out of free test kits. We hope to have more kits available in the near future. Please check back.  We apologize for any inconvenience.  If you are interested in testing now, test kits are available for purchase at your local hardware store. If you have any questions about radon, please don't hesitate to call us at 937-642-2053.


If you are unable to complete the online form for any reason, please email us at contact@uchd.net or call us at (937) 642-2053 and we will ensure a test kit is ordered on your behalf. 


The FREE test kit is easy to use.
1. Place the test kit in the lowest living level of your home. That means a finished basement if your family spends time there or it may mean your first floor if you only use the basement for storage.

2. Leave the kit in place for three to seven days. 

3. Remove and discard the sponge from the kit. Seal the bag and mail to the testing company.

4. Your results will be mailed to you in about two weeks. The Ohio Department of Health also receives the results so that radon levels throughout the state can be tracked.

 If your home has radon levels over 4 picocuries per liter, mitigation is recommended. Mitigation costs can be several hundred dollars or more, but is important for the health of your family as exposure to Radon is the second leading cause of lung cancer. The Ohio Department of Health has a list of all licensed Radon contractors which you can find by following this link.  If you have any questions, please call the Union County Health Department at (937) 642-2053 for more information on radon testing and mitigation.

What you need to know about Radon

Due to naturally occurring high levels of Radon in the soils of Central Ohio, the EPA recommends all Union County homeowners test their home for radon.  Radon is a naturally occurring odorless/colorless gas that enters into a building that is in contact with the ground, like basements. Because it is a gas it can enter through many different avenues including cracks in the foundation of a home, construction joints and gaps around service piping. High levels of Radon are very dangerous and can cause serious health complications. The EPA states that Radon is the second leading cause of cancer in the general population and the leading cause among non-smokers. 


The average national indoor radon level is 1.3 pCi/L (picocurie per liter).
The average indoor radon levels of Union County, as determined by radon test results from Air Chek, Inc, is 4.9 pCi/L

    Results under 2 pCi/L

    Results between 2 and 3.9 pCi/L

    Results 4 pCi/L and above
