Radioactivity level of natural Arizona White granite material can be divided into A, B, C categories. A class of products can be used in office and family room, B radioactive products is higher than A class, not for the interior surface of the room, but can be used both inside and outside the building finishes; C higher radioactive products can only be External finishes on the building.

Natural Arizona White granite material, the radiation is a Class A, including cherry red, general red, Taiwan red, Xinjiang red, Isle Red, Anxi Red, Maple Red, Xili Red, white linen Tianshan, Tianshan red and Xiamen red; belongs to Class B Guilin, including Indian Red, and red; are C classes of goods for the Yongding red, and red azaleas in some places, radioactivity levels to greater than the C class standards.

There was a rumor that you can tell by the color of the stone the level of its radioactivity. In fact, according to state departments of testing, the color can not serve as a basis to determine the radioactivity. If there is a red stone radioactive high and low, red azalea, South Africa, red, Indian red and so high, some B, C class, and a lot of red stone, such as Anxi Red, Maple Red is A class of products. In short, the stone needs to the relevant units of radioactive detection of the data subject.
