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 the granite can emit radiation. However, it is extremely unlikely that granite countertops in homes could increase the radiation dose above that the normal, natural background dose that comes from soil and rocks. You can learn more about this topic at the following EPA Radiation Protection page: http://www.epa.gov/radiation/tenorm/granite-countertops.html

Information about radon including Frequently Asked Questions (FAQs), related publications, how to locate a qualified radon service professional in your area can be found by visiting the EPA Radon (Rn) homepage: http://www.epa.gov/radon/

Some states "regulate" or "qualify" providers of radon measurement and mitigation services by requiring registration, certification, or licensing.
