Will My Granite Emit Radiation Or Radon?
After an extensive series of tests were recently conducted on all of the major types of granite used for countertops, it was determined that granite is not a significant source of radon gas and the small amount of the gas found was far below the level even requiring reporting by the EPA.
According to a report published by Environmental Health & Engineering, Inc., “doses of ionizing radiation emitted from granite countertops are well below levels that would pose a health concern and contributions from granite countertops to radon levels in homes are lower than background levels of radon exposure typically found outdoors and indoors.”
The report also states that in a common home, “the surface area potentially emitting radon may be 40 times higher for gypsum (sheet rock) than for granite countertops, and 10 times higher for concrete.”

In summary, granite is not a significant source of radiation or radon gas. And, when compared with other manufactured products commonly found in homes (i.e., sheet rock and concrete) that are sources of radon, it is even less significant.
