Why It Matters in Iowa

## What Do These Numbers Mean for Your Home?

Every one of Iowa's 99 counties is in EPA Radon Zone 1, the highest-potential category, and radon is the second leading cause of lung cancer. The EPA recommends fixing homes at 4.0 pCi/L or higher and considering it between 2.0 and 3.9 pCi/L.

These tools give you a quick read on where you stand. For a real estate deadline or a mitigation decision, a professional test from an Iowa HHS-credentialed technician is the next step.
