Date Published: 01/04/2007 [Source]

Marathon County's Health Department tested thousands of homes in Marathon County since 1985, and found that two out of three houses had radon.. Radon gas comes from a break down of uranium, which stems from granite... And because the area is loaded with this rock, Marathon County has the most radon in the state.
