In addition to the high requirements for the robustness and environmental protection of the board, marble furniture also has strict control on the radioactivity of the marble. For a long time, people have mistakenly thought that marble furniture will have radiation, and it is inevitable that there are some concerns when buying. In fact, the radioactivity of marble is very low and basically does not cause harm to the human body.
It is a fact that marble has radiation. It should be said that any stone has radiation. It depends on the size of the radiation. As for the radioactivity of marble, experts from the Standardization Research Institute of the State Administration of Building Materials believe that natural radioactivity exists objectively in nature. Similarly, There is also radioactivity in natural marble products, the key is to see whether it exceeds the national standard. Marble is made of limestone in sedimentary rock that has been affected by external factors such as temperature and pressure. Because the radioactivity of calcite and dolomite composed of it is generally very low, the radioactivity of marble metamorphic from limestone with very low radioactivity is also very low.
