No, granite countertops do not typically emit significant levels of radon. Radon is a radioactive gas that is naturally occurring in soil, rock, and water, and it can accumulate in enclosed spaces such as homes. While granite is a natural stone that contains trace amounts of radioactive elements, the levels are generally very low and not considered a health hazard when used in countertops or other building materials.
However, it's always a good idea to have your home tested for radon levels, regardless of the materials used in its construction, to ensure that the air you breathe is safe. If high levels of radon are detected, there are steps you can take to mitigate the risk, such as installing a radon mitigation system.
