Most of us think of our homes as safe havens from the rest of the world, but what if the air inside is making it anything but safe? We asked Barry Westbrook, a certified industrial hygienist and owner of DocAir, an indoor air quality firm based in Franklin, Tennessee, to sound off on four pollutants that could be mucking up the air inside your home.
What is it?
Radon is a radioactive gas that results when uranium breaks down.
Where it can be found in your home
It can be in the soil beneath and around your house; it enters your home through cracks and openings.
Why it's dangerous
Exposure to radon is the second leading cause of lung cancer after smoking, according the U.S. Environmental Protection Agency.
How to detect it and protect your family
You can test for radon yourself by buying a radon test kit or monitor for about $30 at home improvement stores.
