Are your kitchen countertops killing you? Stop laughing -- I'm being serious here. There might be a very real and potentially deadly source of radioactive gas in your home--your granite countertops. According to this article from the New York Times, granite countertops can contain high levels of Uranium, which is radioactive in itself, and when it decays, it releases radon, a radioactive gas. If that's not frightening enough, consider this: radon can cause lung cancer.

Not all granite countertops are dangerous, but have the potential to be. What can you do to protect yourself? Test the merchandise before you buy it by hiring a certified technician to measure your radiation levels or picking up a DIY tester from the Environmental Protection Agency.
