The radionuclide decay in the air in the air enter the body, or attached to the tracheal mucosa and lung surface, or into the body fluid into the tissue formation in vivo radiation induced lung cancer, leukemia and respiratory disease. The harm of artificial marble is mainly manifested in the pollution caused by inferior material.
Sound identification method: when made of marble, we use the hand to knock out the sound is crisp and sweet, while the texture of marble is poor.
Identification method: natural marble color is bright, there will be a large area of natural and artificial marble texture, color slightly turbid, and no natural grain; there is a way, we can be on the table a few drops of dilute hydrochloric acid, natural marble will be severe foaming, artificial marble is weak or even no blistering foaming. On the marble with a fine material structure of the stone, looks very texture. Pay special attention to the cracks in the stone image, once found to have this image will be removed, because it is easy to break. But to distinguish between the crack and the pattern.
