Radon exposure is the second-leading cause of the lung cancer, next to smoking.

With January being National Radon Action Month, the Northern Michigan Public Health Alliance recommends that all homes be tested for radon. Radon is found in soil and rock and is an odorless, colorless, and radioactive gas that leaks into homes through cracks or openings in basement walls, ground floors, and crawl spaces.

From Jan. 28 to Feb. 1, District Health Department No. 4 is offering discounted radon kits for $5.

For more information about how to test for radon, contact the health department at 989-356-4507.
