You can't see it, you can't smell it, and you can't taste it, but radon may be present in your home. Radon is a naturally occurring, invisible, odorless, and tasteless gas that is dispersed in outdoor air and can reach harmful levels when trapped in buildings.
Radon is found in a majority of homes, as Iowa leads the nation for the highest percentage of homes with elevated indoor radon levels. The Iowa Department of Public Health (IDPH) says approximately 72% of basements or levels in contact with soil have high radon.
