Radon is a harmful odorless gas and it's the leading cause of lung cancer for non-smokers. There could be high levels of radon in your home right now and you'd never know unless you get it tested. The North Carolina Department of Health and Human Services is offering 3,000 free radon test kits for North Carolina residents, so you can test the levels in your home. If you're interested in one of the free kits you can apply for a free test kit on the NCDHHS website HERE
