Why Iowa Homes Test Higher for Radon Than Almost Anywhere in America
Radon is a naturally occurring radioactive gas that seeps up from the ground. Iowa’s glacial-till soils sit over uranium-bearing bedrock, and that geology produces more radon than almost any other place in the country. The state average is around 8.5 pCi/L, compared with a US average near 1.3 pCi/L, and roughly 71.6% of Iowa homes test above the EPA action level of 4 pCi/L. All 99 Iowa counties sit in EPA Radon Zone 1, the highest-risk category.
Radon is the second leading cause of lung cancer after smoking, according to the EPA. You cannot see it or smell it, so a test is the only way to know your home’s level. The encouraging part is that radon is fixable. A sub-slab depressurization system vents soil gas safely above the roofline, and a credentialed specialist re-tests afterward to confirm the level dropped.

When Iowa Homeowners Should Test or Mitigate for Radon
Radon has no smell and causes no symptoms. Testing is the only way to know.
- 1
You have never tested. Most Iowa homes have elevated radon, and testing is the only way to know yours.
- 2
Your test came back at or above 4 pCi/L. That is the EPA action level where mitigation is recommended.
- 3
You are buying or selling a home. A radon contingency or Iowa disclosure can put testing on a tight timeline.
- 4
You finished a basement. Adding living space below grade increases time spent in the highest-radon part of the home.
- 5
You have a new baby or someone with respiratory issues. Long-term radon exposure is a health risk worth ruling out.
- 6
Your home is more than a few years old and untested. Radon levels can change over time, so an old result is not the final word.
- 7
A neighbor tested high. Nearby geology is similar, though every home should be tested on its own.

Frequently Asked Questions
Why is radon so high in Iowa?
Iowa sits on glacial-till soils over uranium-bearing bedrock, and all 99 Iowa counties are EPA Radon Zone 1. The state average is around 8.5 pCi/L compared with a US average near 1.3 pCi/L, and roughly 71.6% of Iowa homes test above the 4 pCi/L action level, according to the EPA and Iowa HHS.
How much does radon mitigation cost in Iowa?
According to published Iowa contractor pricing, a standard sub-slab system typically runs about $800 to $2,500, with a median near $1,400. The specialist you are matched with provides a written, itemized quote before any work.
How long does a mitigation system take to install?
For a standard home, a sub-slab depressurization system is typically installed in about one day. Crawl spaces or homes with multiple foundation areas can take longer.
What radon level is dangerous?
The EPA sets an action level of 4 pCi/L, the point at which it recommends reducing radon. Radon is the second leading cause of lung cancer after smoking per the EPA, and there is no completely risk-free level, so lower is better.
Do I need to test before I sell my home in Iowa?
Iowa requires sellers to disclose known radon test results, and many transactions include a radon contingency, so testing commonly comes up during a sale. A specialist can run a transaction-timeline test to keep your closing on schedule.
Does a mitigation system really lower radon below 4 pCi/L?
Properly installed systems typically reduce radon by 50 to 99% according to the EPA, and the specialist re-tests after installation to confirm the result. The specific final number is reported by the specialist after that test.
