Frequent Questions

What information do you have about radon and radiation in granite countertops?

Any type of rock including granite could contain naturally occurring radioactive elements. If present, these radioactive elements will decay into radon, a colorless, odorless, radioactive gas which may be released from the granite over time. In addition to radon, the other natural radioactive material in granite can emit radiation. However, it is extremely unlikely that granite counter-tops in homes could increase the radiation dose above the normal level.
