Radon

Iowa has some of the highest radon levels in the nation. By July of 2027, every public school building in Iowa must have tested for naturally occurring, cancer-causing radon gas. They're also required to post the results of that testing on their websites. With two years to go, fewer than half of school districts have met that requirement. We look at why many schools aren’t testing for radon — and how the Iowa Department of Education has responded to an investigation by 'The Midwest Newsroom.' (This episode was originally produced Oct. 14, 2025.)

Iowa has some of the nation’s highest radon levels. We look at why many schools still haven’t been tested for the radioactive gas — and what’s at stake.

A law to protect students and school employees from the radioactive gas has an approaching deadline. The Midwest Newsroom has found that progress is uneven across Iowa's school districts. Private schools are exempt from the testing requirement.
