Yes, you can put food on your granite countertop without worrying about radiation contamination. Granite, like many other natural stones, contains trace amounts of naturally occurring radioactive elements such as uranium, thorium, and their decay products (e.g., radon). These elements emit low levels of radiation, but the radiation levels in granite countertops are typically too low to pose any health risks.
The radiation from granite countertops is considered negligible and is not a concern when it comes to food safety. Granite countertops have been extensively studied, and various health organizations, including the United States Environmental Protection Agency (EPA), have concluded that the radiation levels in granite countertops are well below any level that could be harmful.
The radiation levels in our daily environment from natural sources are quite low and considered safe. In fact, we are exposed to background radiation from sources like soil, rocks, and even the air we breathe. The radiation from granite countertops is just one of these sources and is not considered hazardous.
As long as your granite countertop is clean and maintained properly, it is safe to place food on it. Proper food handling and preparation practices are more critical for food safety. Always make sure to clean your countertops regularly with mild soap and water, use cutting boards for food preparation, and practice good hygiene to ensure your food remains safe and free from contamination.
