This month, Health Departments throughout Michigan want you to pay attention to radon gas.
It is odorless and tasteless.
You cannot see it, but radon gas is slightly radioactive and causes as many as 20,000 lung cancer deaths in America each year.
It is the second leading cause of lung cancer in this country.
Radon originates in the soil and leaks into your basement through cracks in the foundation.
Kent County Health Department's Lisa LaPlante tells WOOD Radio that radon levels in Michigan are higher than the national average with roughly one-in-eight homes testing at dangerous levels.
Kent County's Health Department will sell you a test kit for $5.
Ottawa County Health Department's Kristina Wieghmink says their kits are $10, available at the office in Holland.
Either kit requires sampling the air for one week in your basement, when the house is closed as it is in the winter.
There's more information on radon, testing, and fixes at the U.S. EPA website.
