In recent years, there have been numerous media reports about possible health concerns regarding granite countertops emitting radiation and radon gas into people's homes.

Any type of rock could contain naturally occurring radioactive elements such as radium, uranium and thorium. Some pieces of granite contain more of these elements than others. If present, these radioactive elements will decay into radon, a colorless, odorless, radioactive gas which may be released from the granite over time.

According to the U.S. Environmental Protection Agency, "It's important to know that radon originating in the soil beneath homes is a more common problem and a far larger public health risk than radon from granite building materials."
