You can’t see, smell or taste radon in your home. But that doesn’t mean it isn’t there, according to Dr. Jon Cole of the Minnesota Poison Control System. “You have no symptoms while it’s happening, and then later on, eventually you … develop lung cancer,” Cole said. Radon is the leading environmental cause of lung cancer deaths in the U.S.
Drive down any residential block in Minnesota and the hidden risk of radon is there. That’s because according to state health experts, 40 percent of all homes have radon levels above the danger threshold.
