Radon is an invisible, radioactive gas created from NATURAL deposits of uranium in the ground. Radon gas can be drawn into a building and build-up to levels that can cause a health concern. Finding high levels of radon in the home has nothing to do with the age, quality, or upkeep of th ehome. Be sure that your home is safe! Come in and get a radon test kit. These test kits are FREE for the month of January at the Lenawee County Health Department.
