Radon is an important concern for Iowa homeowners, buyers and sellers. It is a naturally occurring radioactive gas that can enter a home through cracks, sump pits, floor drains and other openings in the foundation.
Because radon has no color, smell or taste, testing is the only way to know whether it is present in your home.
Why is radon common in Iowa?
Iowa has some of the highest radon potential in the country. The Environmental Protection Agency classifies every Iowa county as a high-risk area for elevated radon levels.
According to the Iowa Department of Health and Human Services, more than 70% of Iowa homes tested in a statewide survey had radon levels above the EPA’s recommended action level of 4 picocuries per liter.
Radon can be found in homes of any age, size or foundation type. An older home is not automatically more likely to have high radon, and a newly built home is not automatically protected.
What radon level is considered high?
Radon is measured in picocuries per liter, or pCi/L.
The EPA recommends taking steps to reduce radon when a home tests at 4 pCi/L or higher. Homeowners may also consider mitigation when levels fall between 2 and 4 pCi/L.
A previous low test result does not guarantee that levels will always remain low. Weather, renovations, foundation changes and ventilation can all affect radon levels over time.
Should you test for radon when buying an Iowa home?
Yes. Radon testing is commonly completed during the home inspection period.
Buyers should ask whether the home has previously been tested, when the test took place and whether a mitigation system has been installed. Even when previous results are available, a new test may provide a more accurate picture of the home’s current radon level.
Testing is also worthwhile for current homeowners, especially when:
The home has never been tested
A previous test was completed several years ago
The basement has been finished
Major renovations were completed
A mitigation system is already installed
How do you test a home for radon?
Homeowners can purchase a short-term radon test kit or hire a certified radon measurement professional.
Short-term kits are typically placed in the lowest regularly used area of the home for several days and then sent to a laboratory. Professional testing is often preferred during a real estate transaction because it provides documented results and helps ensure proper testing procedures are followed.
Can high radon levels be fixed?
Yes. A high radon result does not necessarily mean you should avoid buying or selling the home.
A certified radon mitigation professional can install a system that draws radon from beneath the foundation and vents it safely outdoors. The home should then be tested again to confirm the system is working properly.
Radon testing offers peace of mind
Radon is common in Iowa, but it is also manageable. A simple test can help homeowners understand their risk and decide whether additional action is needed.
