The radioactivity of marble is very low, basically won't cause harm to human body. The marble radiation is a fact, it should be said that any stone have radiation, radiation depends on the size of the problem, the marble radioactive, experts on the State Bureau of building materials standard that, in nature, the natural radioactivity is the objective existence, also, there are natural radioactive stone products, the key is to see it if exceed the standards prescribed by the state. Marble is formed by the influence of external factors such as high temperature and high pressure. Because of the low levels of radioactivity in the composition of calcite and dolomite, the radioactivity of the marble, which is made up of very low radioactive limestone.
