Story County has an EPA zone and its own CDC test figures, shown below. About 68,220 people live in Ames.

Should I test my home in Ames?

Yes. Testing is the only way to know the radon level in a specific building. EPA recommends fixing a home when the radon level is 4 pCi/L or higher. EPA recommends considering a fix when the level is between 2 and 4 pCi/L. How to test a home.
