我国把自然饰面石材按放射性辐射强度划分为三个等级(类别):
  Natural decorative stone materials are classified into three grades according to radiation intensity in China.
  A类石材
  Class a stone
  装修资料中自然放射性核素镭-226、钍-232、钾-40的放射性比活度同时满足IRa≤1.0和Ir≤1.3请求的为A类装修资料。A类装修资料产销与运用范围不受限制。自然大理石属于A类,也就是说自然大理石不会对人体产生危害,可放心运用在任何场所。
  The specific radioactivity of natural radionuclides radium-226, thorium-232 and potassium-40 in decoration materials satisfying both IRa < 1.0 and Ir < 1.3 requests are category A decoration materials. Class A decoration materials are not restricted in production, marketing and use. Natural marble belongs to category A, that is to say, natural marble will not harm the human body, can be used in any place at ease.
  B类石材
  Class B stone
  不满足A类装修资料请求但同时满足IRa≤1.3和Ir≤1.9请求的为B类装修资料。B类装修资料不可用于I类民用建筑的内饰面,但可用于I类民用建筑的外饰面及其他一切建筑物的内、外饰面。
  Class B decoration materials that do not satisfy the requirements of Class A decoration materials but also satisfy the requirements of IRa < 1.3 and Ir < 1.9. Class B decoration materials can not be used for the interior decoration of Class I civil buildings, but can be used for the exterior decoration of Class I civil buildings and the interior and exterior decoration of all other buildings.
  C类石材
  Class C stone
  不满足A、B类装修资料请求但满足Ir≤2.8请求的为C类装修资料。C类装修资料只可用于建筑物的外饰面及室外其他用处,须限制其销售,也就是说C类石材只可户外了。
  Category C decoration materials that do not satisfy the requirements of Category A and B decoration materials but satisfy the requirements of Ir < 2.8. Category C decoration materials can only be used for exterior decoration of buildings and other outdoor uses. Sales of Category C stone materials must be restricted, that is to say, they can only be used outdoors.

  至于Ir>2.8的石材就只能用于路基、涵洞、水坝、海堤和深埋公开的管道工程等远离人们生活的场所。山东锈石主要以无臭点、无黑斑、多锈点、锈点明晰而且为深黄色锈点为质量上乘,优质的光面黄锈石被界内以为是外墙干挂的石种,烧面和荔枝面所加工成的地铺石、景观石是景观设计师喜欢的选择。
  As for Ir > 2.8 stone, it can only be used in roadbed, culverts, dams, seawalls and deep-buried open pipeline projects which are far away from people's lives. Shandong rust stone is mainly odorless, no black spots, multi-rust spots, clear rust spots and dark yellow rust spots for quality, high-quality smooth yellow rust stone is considered to be the preferred stone for dry hanging of external walls within the boundaries, burnt noodles and litchi noodles processed into paving stones, landscape stones are the favorite choice of landscape designers.
  可用做磨光板,火烧板,薄板,台面板,环境石,地铺石,路延石,小方块,墙壁石,石制家具,石雕及各种建筑工程配套用石材。
  It can be used as polishing board, fire board, thin board, table panel, environmental stone, floor paving stone, roadstone, small block, wall stone, stone furniture, stone carving and all kinds of stone materials for supporting construction projects.
