00:00Scientists have just identified a silent cancer trigger hiding in plain sight inside most
00:05American homes, and most families have no idea it's there.
00:09A new analysis from the American Cancer Society and Environmental Protection Agency has linked
00:15sustained indoor radon exposure to a sharp rise in lung cancer cases among non-smokers.
00:22Radon is a colorless, odorless, radioactive gas that seeps up from the ground into basements,
00:28crawl spaces, and ground floor rooms. The CDC now estimates that radon causes around 21,000 lung
00:36cancer deaths in the United States every single year, making it the second leading cause of lung
00:41cancer behind smoking. Worst affected states include Pennsylvania, Iowa, Ohio, Colorado, and Minnesota,
00:50where natural geology pushes radon levels much higher. A radon test kit costs less than $30 at
00:57most U.S. hardware stores. If levels are above 4 picocuries per liter, the EPA recommends a
01:03mitigation system, which typically costs $800 to $1,500. It's invisible. It's odorless.
01:11And right now, it could be inside your home.
