Why Sioux City Homeowners Should Take Radon Seriously
Radon is a naturally occurring radioactive gas produced by the breakdown of uranium and radium in soil and rock. It is odorless and invisible. When it seeps into a home and builds up, breathing it over years raises the risk of lung cancer. The EPA says radon is the number one cause of lung cancer among non-smokers and is responsible for about 21,000 lung cancer deaths in the United States each year.
Iowa is one of the highest-radon states in the country. The EPA places all 99 Iowa counties, including Woodbury County where Sioux City sits, in Zone 1, the highest category, meaning the predicted average indoor level is above 4 pCi/L. The Iowa Department of Public Health reports an average indoor level in Iowa of 8.5 pCi/L, compared with 1.3 pCi/L for the United States as a whole, and estimates that as many as 5 in 7 Iowa homes have elevated radon. The state also cites an EPA estimate of roughly 400 radon-related lung cancer deaths a year in Iowa.
Maps and averages describe regions, not houses. The only way to know the radon level in your home is to test it.

The Basic Path: Test, Decide, Fix, Retest
- Test. Use a short-term test kit or a credentialed measurement professional. Test the lowest lived-in level of the house.
- Decide. The EPA recommends fixing your home at 4 pCi/L or higher and says to consider fixing between 2 and 4 pCi/L.
- Fix. If you need mitigation, hire a credentialed professional. A typical system includes a suction point in the soil under the house, a vent pipe and a fan.
- Retest. Confirm the system works. Test again after renovations or other major changes to the house.

Common Questions
Is radon really a problem in Sioux City?
Radon is a problem across Iowa. The EPA places every Iowa county, including Woodbury County, in Zone 1, the highest predicted radon potential. Levels vary from house to house, so testing your own home is the only way to know.
What radon level means I should fix my home?
The EPA recommends fixing your home if the radon level is 4 picocuries per liter (pCi/L) or higher, and says to consider fixing between 2 and 4 pCi/L.
Can I test for radon myself?
Yes. Short-term test kits are widely available, and the Siouxland District Health Department has sold them to the public. Follow the instructions closely, and consider a credentialed measurement professional if you want help or are in the middle of a home sale.
Does a home without a basement have radon?
It can. The Iowa Department of Public Health says radon is found in homes with and without basements, and in new and old homes.
