Natural stone refers to the general term for the products that have been mined from natural rock masses and processed into blocks or plate-like materials. The natural stone used for building decoration mainly consists of granite and marble.

People who have noticed the interior decoration of 4-star or 5-star hotels will have a discovery: natural stone exists in the hotel lobby, the bathroom inside the room, the living room wall, etc., and the overall sense of the interior decoration will be due to the use of the stone. And more refined and gorgeous. But why is modern home improvement still dominated by tiles or wooden floors? How far is the popularity of natural stone home decoration still has to go?

When many consumers talked about the unwillingness to use natural stone as a material for interior decoration, the main issue discussed was radiation. To this end, we visited the China Stone Association and the National Stone Inspection Center. The expert’s reply was: China’s building stone products mainly consist of marble and granite. In this center, the detection of radioactive materials for all 1,000 kinds of stone materials in China has been completed. The data, in which the radioactive index of marble is about 0.02, is similar to that of soil; the vast majority of radioactivity of domestic granite is also far below the standard index and has a large enough safety factor. Therefore, the misunderstanding of natural stone needs to be eliminated with the help of the society.

Radioactive classification of natural stone Radioactivity levels of natural stone can be divided into three categories: A, B, and C. Class A products can be used in office buildings and family rooms. Class B products have higher levels of radioactivity than Class A and cannot be used for indoor interiors, but can be used for interior and exterior finishes of buildings; Class C products are more radioactive and can only be used On the exterior of the building.

Among the natural stones, radioactivity belongs to Class A, including Sakura Red, General Red, Taiwan Red, Xinjiang Red, Shidao Red, Anxi Red, Maple Leaf Red, Xili Red, Tianshan White Hemp, Tianshan Red, and Xiamen Red; Including the Indian Red and Guilin Red, etc.; belong to the C category of goods for the Yongding Red, and some places in the Azalea, the level of radioactivity is greater than the C standard.

There have been rumors that the level of radioactivity can be determined by the color of the stone. In fact, according to tests conducted by the relevant national authorities, color cannot be used as a basis for judging its radioactivity. If the red stone has high or low radioactivity, Rhododendron red, South African red, Indian red and other high, some are B, C class, and a large number of red stone, such as Anxi red, maple red is a class A product. In short, the radioactivity of stone needs to be based on the data detected by the relevant unit.
