国产的大多数建筑材料的放射性水平低于国家标准所规定的限值。但少数材料尤其是花岗岩及掺煤渣(或粉煤灰)的制品的放射性核素含量可能超出限值。由于建筑材料的放射性污染对于人民健康有重要影响,对此问题应给予重视并加强监督检查。 The radioactivity level of most domestic building materials is lower than the limit set by national standards. However, the radionuclide content of a few materials, especially granite and cinder (or fly ash) products, may exceed limits. Due to the radioactive pollution of building materials has an important impact on people’s health, attention should be paid to this issue and supervision and inspection should be strengthened.
