• Radon

Is a naturally occurring gaseous element that escapes from granite as other natural elements like uranium break down. Once it is a gas it's inhaled and after a short while it breaks down into Polodium, Bismuth and Lead where it releases radiation, mutating your cells and causing cancer. The EPA's Citizens Guide to Radon can be found here.

Radon is second leading cause of Lung Cancer in America.
