(Radio Iowa) – Iowans are being urged to check their homes this month for an invisible threat. Shelby Kroona (KROO-nuh), director of the Hamilton County Public Health Department, says anyone in the state could be living in a hazardous environment and not realize it.

January is Radon Awareness Month and she says that’s because this is typically one of the coldest months of the year and
people are often cooped up indoors.

She encourages everyone to buy a radon test kit though your local health department or at home improvement or hardware stores. They usually cost around 15-dollars.

If your test kit registers a two, you’ll just need to keep watch, but with a four or above, you’ll need to install a radon mitigation system in your home. Learn more at radon.org
