Free radon test kits are being offered by District Health Department No. 10.

One in eight homes in Michigan are expected to have a problem with the naturally occurring gas that is found in rock and soil.

Often, radon can enter a home through cracks in its foundation, and the gas has the potential to build up and become harmful.

Radon is invisible, odorless, radioactive, and is the number one cause of lung cancer among non-smokers.

The kits can be ordered by calling the Mecosta – District Dept. #10 at 231-592-0130.
