There are two types of stone, marble and granite. The radioactivity of marble is generally lower than that of granite, and most of it can be used for interior decoration. However, granite is not suitable for indoor use, especially in the bedroom, the elderly, and children's rooms.
According to tests, color also has a certain influence on radioactivity. Red and green have the highest radioactivity, white and black are the lowest. Therefore, red, brown, green, or granite with red spots should be carefully selected. In addition, China's stone is divided into A, B, and C according to the level of radioactivity. According to regulations, only Class A can be used for home interior decoration.

How to use: Strengthen ventilation, dilute and contaminate After laying stone, pay attention to dilute the pollution. The simplest method is to strengthen ventilation. The room that has just been renovated is best to be checked by a professional organization.

If the radioactive index is too high, the stone must be replaced immediately.
