A new study of the most popular granites used for kitchen countertops in the United States concludes that granite is safe to use in kitchens.
The study, designed to determine whether radon gas sometimes released by natural stone poses any health risk, was conducted by an independent geochemistry researcher. Included in this study were 13 of the most popular types of granites used in countertop applications, representing up to 85 percent of the granite countertops sold in the United States.
