Natural stone and artificial stone which radiation
Currently on the market most of the stone products and did not undergo radioactive inspection, the stone did not write A, B, C. So we determine whether or not there is a type of radiation radiation. Generally speaking: marble is a layer of rock, including the radiation and the soil is basically the same, without considering its radiation problems. Steel flower stone is the volcano rock, containing radioactive substances and the formation of the volcano in the formation of substances, radioactive substances and non-ferrous metals often the same, and compound non-ferrous metal rock color, so we can through the rock color, flower stone is probably that steel containing radioactive substances. In general, there is a greater probability of red and green stone containing radioactive material. Common stone in the following several kinds of steel stone containing radioactive material is more determined: India red / South Africa Red / azalea / cuckoo green. And the general white and black stones do not have radiation.
People are very concerned about the radiation problem of natural stone, concrete analysis of specific issues. Some stones contain uranium, radium, thorium, potassium and other radioactive substances, radium decay radon, harmful to the human body. The national standard A, B, C stone into three categories: according to experts, natural stone and tiles according to the radioactivity level of ABC is divided into three categories: > (only a class a product can be used indoors) can be used in any occasions, including office and the family room. Such as red, cherry red, general red, Taiwan red, Xinjiang red, Shidao red, Anxi red, red maple leaf, West Tianshan Tianshan red, white linen, red, red, red, Xiamen, South Africa is a commodity; B products of radioactive level is higher than that of a class can be used for the bedroom interior surface, but can be used in the other all the buildings inside and outside decoration. Natural stone products in the category of radioactive B red, India red; C class of radioactive products are higher than A, B two categories, can only be used for building exterior finishes. Which belongs to the C class of goods for Yongding red; more than C standard control value of natural stone, can only be used for the seawall, piers and stone and other purposes. Red azalea.
