Granite is a natural stone that is composed of several minerals, including uranium and thorium, which are both radioactive elements. The amount of radioactivity in granite varies depending on the specific type of granite and its location.
A study conducted by the National Center for Environmental Health and the United States Geological Survey found that some types of granite can emit high levels of radiation, up to 10 times the average background radiation level.
Exposure to high levels of radiation can increase the risk of developing cancer and other health problems. However, it is important to note that the radiation emitted from granite countertops is typically not high enough to pose a serious health risk.
