Stone carcinogenic? Stone radiation? Stone consumer common questions to answer

If stone was bad for us, we would have died out a long time ago, and our ancestors, cavemen, lived in stone caves. Shandingdong Man, a human fossil of the upper Paleolithic age in North China, belongs to late Homo sapiens. It is named after the cave found at the top of the Beijing Ruins of Longgu Mountain in Zhoukoudian, Beijing. It was discovered in 1930. From 1933 to 1934, the Cenozoic Research Office of China Geological Survey was excavated by Pei Wenzhong.

Stone has witnessed the development of human civilization history, from the Paleolithic age to the Neolithic age, to learn to live in stone caves and so on, if the stone is harmful to the human body, human would have been extinct.

Often have consumer when buying building materials, because hear too much fallacy rumour dare not use stone material.

Can natural stone contain radioactive material cause cancer? 

It has become widely known that natural stone contains radioactive substances that can cause cancer. So is it true that marble contains excessive levels of radioactive material that could endanger human health?

The answer to this question was obtained after experts tested and studied. The research proved that natural time rub is the volcanic rock formed by metamorphic rock or magma under the earth’s surface after the original rock in the crust was formed by high temperature and high pressure.

In essence, the term earth constitutes a part of the radioactive material content and soil close, most of the natural stone is harmless to human body.

In response to this problem, professionals have also issued the “White Paper on Natural Marble in China (2013)” to clarify the claim that excessive radioactivity in natural stone can cause cancer.

Natural stone radioactive material dare to rest assured to use?

According to the national standard implemented in July 2011, decoration materials are divided into A.B.C three categories according to the level of radioactivity index.

According to the national Stone Quality Supervision and inspection Center for A variety of domestic and imported natural stone samples of radioactive results show that the average radionuclide activity of all the marble samples tested is 0.02, only A national standard, (Radioactive specific activity at the same time to meet IRa,(internal exposure index) less than 1.0 and Iy(external exposure index) less than or equal to 1.3) index of one fiftieth, and granite is also far below the index value, almost negligible, and the safety index of natural stone is better than other general decorative materials.

In addition, there is no requirement to detect the radioactivity of natural stone products in China’s current marble product standards, entry inspection and quarantine, and building materials products in the field of architectural decoration engineering, indicating that they do not pose harm to human beings and can be safely used without detection.
