The seriousness of the implementation of the standard Stone radioactive identification is a very professional thing, do not have the expertise of people is difficult to figure out, especially in recent years, some express, so that people have a fear of speech, has caused people to panic of consumption of stone , We are very worried about this. Of course, is not that: since Disadvantages Of Composite Decks Materials Sri Lanka the radioactive, the degree of harm is no definite quantitative conclusion, but also talk about stone radioactive problems? This idea is not correct.

The national mandatory standard GB6566-2001 is of a regulatory nature and must be implemented. As stone manufacturers of managers should be given high priority. According to the color to determine the radioactive stone is unscientific According to our national stone radioactive supervision and sampling samples and commissioned samples of the test results show that the color of stone can not be used as a basis for judging build simple benches the radioactive stone. Red stone of radioactive high and low, azalea red, South Africa, red, Indian red and other high, some are B, C class.

And a large number of red stone, such as Wan Shanhong, Luoyuan red is a class of products. Is the same species of stone radioactive also vary from place to place. Such as rhododendron red due to different production, some for the C class products, while others are Class A. Green stone is the case, we have now detected the "rhododendron green", is the highest content of radioactive material stone products, it is not red, but green. However, most of the green stone radioactivity is relatively low. Such as hibiscus green, malachite green and so on. As for the flowers with the stone, there are high and low, it is difficult composite 4x4 posts to distinguish. Black, white is relatively low, but the number of samples measured is not enough to rule out the possibility of their high radioactivity. In short, the stone radioactive can not be from the color point of view, but to be measured by the certification body approved by the unit data shall prevail.
