Steele County Deals With Radon Problem

A dangerous gas is seeping into homes throughout Steele County — a gas that carries adverse health effects — and the homeowners may not be aware of it.

According to data from the Minnesota Department of Health, high levels of radon — an odorless, tasteless and invisible gas that has been known to cause lung cancer — are present in 67 percent of the homes in Steele County.

Two-thirds of the homes in Steele County have levels of at least 4 picocuries per liter. A picocurie is one-trillionth of a curie, an international unit of measurement for radioactivity. Dan Tranter, supervisor of the Indoor Air Unit at the state’s health department, said radon poses a risk to those living in high concentrations.
