ST. CLOUD -- Stearns County is offering free radon testing kits to residents on a first-come first-served basis. The county has a limited number of short-term radon testing kits for residents.

The health department says Stearns County homes have a higher than average potential for increased radon levels due to the area's underlying geology.

Radon is an odorless, colorless gas that has been linked to lung cancer.

To get a free kit, contact the Stearns County Environmental Services Department at 656-3613.
