Is radon really that common in Iowa?

Yes. Iowa has the highest average indoor radon levels of any state — roughly 5 in 7 homes test above the EPA action level — so testing is strongly recommended statewide.

What happens if the level is high?

Radon is fixable. A mitigation system typically vents it safely outdoors, and a retest confirms the level has dropped below the action threshold.
