GRAND JUNCTION, Colo. (KKCO) An stealthy, unwelcome house guest could be in your home and wreaking havoc on your lungs.
High levels of radon are found in one in 15 houses in the U.S. making it the leading cause of non-smoking related lung cancer.
"People think, 'Wow if radon is in my house, i'll smell it,'" said Ted Munkres, who works for Foundation Repair of Western Colorado, which does radon testing and mitigation. "It is odorless, colorless. You cannot see it. The only way you know it's there is by a scientific measurement."
Mesa County is actually more prone to producing higher levels of radon than other geographical areas, Munkres said.
You can find out how much radon is in your home and if it's at an unhealthy level by hiring a professional to use an electronic monitoring system or you can get a do-it-yourself home test kit, which Foundation Repair of Western Colorado is giving out for free this month.
Experts recommend testing your home for radon every two years.
