Stone decoration before the first test

Myth one: deep-ray Multi-Color

    Some people think that the decoration stone darker, the stronger radioactivity. In this regard, experts have said that this statement is not tight. Although in general, as in the case of a class of white marble stone indeed rarely excessive radioactivity, radioactive malachite green, granite is relatively little more, but not necessarily a link between the color depth and intensity of radioactivity. Such as radioactive majority of black stone and will not be exceeded. The real decision radioactivity should be stone "birthplace" is the geological conditions of their origin determine its radioactivity.

Some people think that as long as it will certainly exceeded radioactive marble, experts say, it is not. On the one hand because it is a synthetic artificial marble, it is generally not contain radioactive elements, on the other hand is not even natural marble deeper the color will be exceeded. City Environmental Quality Supervision, Inspection Station last year had marble, granite and other 10 kinds of stone over testing, the results are all qualified marble, granite touches more than 40% of class A limit (ie not suitable for indoor decoration materials).
