Several state-based health and environmental agencies have issued statements that granite countertops typically found in homes do not pose a health risk to consumers.
The latest to comment on this are the Florida Department of Health,
Texas Department of State Health Services, New
Jersey Department of Environmental Protection, North Carolina Geological Survey
and Washington State Department of Health. All acknowledged that some gamma
radiation may be emitted by granite countertops but, as the New Jersey Dept. of
Environmental Protection pointed out, “Radiation is all around us.” They also noted that the levels emitted were
not viewed as a "significant" hazard.
