The use of stone mill is clearly stipulated that radioactivity is not included in the scope of radioactivity inspection. It itself is an environmentally friendly, green and reassuring stone; It has uniform particles, fine texture and moderate hardness. It is a compound mineral that is harmless to organisms and has certain biological activity. It is beneficial to human body and zero radioactive stone; Green sandstone containing more than ten kinds of minerals such as silicon, calcium, new iron oxide is used as raw material [green sandstone is one of all sand rocks with good hardness. It does not drop slag and do not make a mess when grinding food

绿砂岩是一种亚光石材，不会产生因光反射而引起的光污染，又是一种天然的防滑材料，绿砂岩石零放射性石材，对人体无伤害，大理石，花岗石都存在微量放射性，长期生活在其中对人体会有潜移默化的伤害。

Green sandstone is a kind of Matt stone, which will not produce light pollution caused by light reflection. It is also a natural anti-skid material. Green sandstone rock is zero radioactive stone, which does no harm to human body. Marble and granite have trace radioactivity, which will cause subtle harm to human body if they live in it for a long time.
