Marble radiation problem
China's marble production areas are concentrated in Shandong, Zhejiang, Fujian, Guangdong and Guangxi provinces.
Marble furniture has high requirements on the soundness and environmental protection of the board, and strict control on the radioactivity of the stone. For a long time, people mistakenly thought that marble furniture would have radiation, so they inevitably had some concerns when purchasing. In fact, the radioactivity of marble is very low and will not cause harm to 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. For the radioactivity of marble, experts from the Standardization Institute of the National Building Materials Administration believe that natural radioactivity exists objectively in nature. Similarly, there is radioactivity in natural stone products. The key is to see whether it exceeds the national standard. Marble is formed from limestone in sedimentary rock by metamorphism under the influence of external factors such as temperature and high pressure. The radioactivity of calcite and dolomite is generally very low, so the radioactivity of marble metamorphosed from low radioactivity limestone is also very low.
The radionuclide limit of granite and marble slab shall comply with the provisions of GB6566-2001 Limits of Radionuclides in Building Materials.
