Fear vs. Fact
In the age of information, misinformation spreads fast. A common myth is that granite countertops are dangerous. Let's look at the scientific data regarding Radon, Radiation, and Bacteria.
1. Radon & Radioactivity
The Claim: Granite emits Radon gas that causes lung cancer.
The Science: All rocks (including the concrete foundation of your house and the soil in your garden) emit trace radiation because they contain natural minerals like uranium and potassium.
The Scale: A banana is radioactive (Potassium-40). A smoke detector is radioactive. The amount of radon emitted by a typical granite countertop is less than that of the soil beneath your home.
EPA Stance: The US EPA states that granite countertops are rarely a significant source of indoor radon. Ventilation in a normal kitchen dilutes any emission to negligible levels.
Our Testing: Ruvello scans exotic stones (which can be slightly higher) to ensure they fall well within safe residential limits.
2. Bacterial Hygiene
The Claim: Granite is porous and harbors bacteria.
The Reality: While granite is porous, a simple sealing treatment makes it hygienic. A study by the Hospitality Institute of Technology found that granite countertops—when washed with soap and water—were more effective at eliminating bacteria than stainless steel (which scratches and traps germs in the grooves).
Comparison: Quartz is non-porous and "safer" in theory, but polished granite like Absolute Black is so dense it is functionally equivalent to glass.
3. Food Safety
Granite is inert. It does not off-gas volatile organic compounds (VOCs) like some laminate glues or synthetic resins. It is a natural material. You can knead dough directly on the surface without worry.
Conclusion
Granite has been used in homes for centuries. It is safe, natural, and hygienic. Don't let fear-mongering push you towards plastic surfaces.
