How does Marquette stack up compared to other counties in the UP? As many of you know, Radon is a gas that can enter and accumulate in homes (actually the decaying by products do). As you also know, high levels of Radon are known to be the second leading cause of lung cancer.
As a whole, upper Michigan has lower to moderate levels of Radon based on EPA and laboratory maps of the continental US. In some parts of the country, Radon levels are scarily high in some residences. Comparing UP counties that have had homes tested for radon in the past, Air Chek has graphs by county showing Marquette to have average tested levels slightly above the mitigation 4 pCi per liter level. Counties such as Houghton and Keweenaw had rather low levels.
It's true that no one can predict which area or which home will test high. There are many factors to consider. What the graphs tell me, is that all homes that have finished living space on the lower (basement) level should be tested for Radon. In Marquette county, a few more will come back high when tested that in other counties.
I'm IAC2 certified to do Radon testing and actually have a website dedicated to doing just that. Give me a call before you close on that new purchase, or if you just want peace of mind regarding your existing home, I'd be happy to test it for you!
