This week on the Today Show they mentioned that the state of Iowa is one of the main states to have cancer causing Radon Gas.    It leaches into buildings out of the soil.    It is a cancer causing, radioactive gas that has no smell, and can only be detected with specialized test 

    In this part of Iowa there are a lot abandoned mine shafts underground everywhere, from when they used to dig for coal in mine shafts here
in the early to mid-1900’s.   they say a lot of that kind of Radon gas is in those old shafts and raising upwards.
    Now a big push is on to test schools in Iowa because Radon has been detected in some of them.
    It seems like there is always something that is hazardous to your health anymore!
