Tiger Onyx Stone

As an industry expert, I present the Tiger Onyx Stone. This unique stone boasts natural striations that add depth and contrast to any interior space. As a result, your home will exude an air of sophistication and elegance. Experience the power of this stone's distinctive beauty.

For a long time, the radioactive problem of natural Tiger Onyx stone has been hyped up by unscrupulous media, which has seriously affected the development of the granite industry. Although today, with the continuous improvement of cognition level, many consumers have been able to scientifically, objectively and fairly understand the radioactivity of stone, but rumors about stone radiation are still everywhere. Even on March 6, 2019, the China Tiger Onyx stoneAssociation and the Organizing Committee of China Xiamen International Stone Exhibition jointly held an all-media conference on "Smashing "Stone Radiation" Rumors, and many authoritative experts in the stone industry jointly spoke out to rectify the name of natural stone. Today, there are still occasional rumors that "granite radiation can cause cancer". Is granite radioactive? have. Is granite radioactive dangerous? Not much. In order to explain the problem, perhaps, we should say, what are the factors that affect the radioactivity level of granite?

01. Geological age

Generally speaking, large-scale granite bases are often complex rock bodies formed by multiple intrusions in one era or in different eras. From the perspective of time, from the Pre-Sinian to the Cenozoic, every tectonic movement will have new granite formation. This actually has a key influence on the formation of the radioactive level of granite. Because, in terms of origin, most of the granites in the Pre-Sinian period were formed by metasomatism, while the granites in the Yanshan period and later were dominated by magma movement, which brought radioactive substances from the deep crust to the surface. one of the main ways. Therefore, from the perspective of actual performance, the newer the geological age of granite, the higher the radioactivity level, from ultra-basic, basic, neutral, acidic to alkaline, the content of radium, thorium and potassium gradually increased. . Taking red granite as an example, products produced in Alxa, Inner Mongolia and Ya'an, Sichuan, such as Sichuan Red and Alxa Red, are mainly collected from Sinian rock formations, mostly neutral or acidic rocks, so their The radioactivity level can often reach the Class A decoration stone standard or the B class decoration stone standard stipulated in the "Radionuclide Limits for Building Materials" (GB6566-2010). in engineering project. However, the granite produced in Guangdong and Guangxi, as well as the granite produced in India, such as Maple Leaf Red, Indian Red, etc., a considerable part of the products are collected from the Yanshanian granite mining areas, mostly acid rocks, and the radioactivity level is only in line with the "Radioactivity of Building Materials" The scope of production, sales and use of the B-type decoration stone standard or C-type decoration Tiger Onyx stone standard stipulated in the Nuclide Limits (GB6566-2010) is greatly limited. This phenomenon has a certain objective reflection in all kinds of granite.
