Did you know that about 1 in 3 minnesota homes have potentially harmful levels of radon gas...the 2nd leading cause of lung cancer in the U.S. If you've never tested your home for radon before, now is the best time to do it. This time of year, our homes are generally closed up more tightly because of the weather, so we're more likely to have a build-up of radon gas or to be exposed to it for extended periods of time.
