(Atlantic, Iowa) – The Cass County Board of Supervisors, during their meeting this (Tuesday) morning, in Atlantic, received a monthly report from Cass/Guthrie County Environmental Health Executive Director Jotham Arber. During his report, Arber had the latest information with regard to Radon Mitigation.

The cost of radon mitigation for an older home, he said, is about $1,500. But the price tag could be much higher, depending on the age and size of a home.

Newer homes are better sealed against radon seeping in to the structure, according to Arber. Iowa has a significant radon problem, according to the EPA, with elevated levels found in a high percentage of homes. Radon is a radioactive gas that can cause lung cancer and is the leading cause of the disease in non-smokers.
