Granite Countertop (Radon Emanation and Silicosis from Fabrication) — household safety profile
Low riskNatural granite countertops that contain trace radioactive minerals (uranium, thorium, potassium-40) which decay to radon gas.
What is this product?
Natural granite countertops that contain trace radioactive minerals (uranium, thorium, potassium-40) which decay to radon gas. EPA and health physics research shows granite countertops contribute negligibly to indoor radon compared to soil (basement) sources. However, fabrication workers cutting, grinding, and polishing granite face severe silicosis risk from crystalline silica dust.
