摘要
《建筑材料放射性核素限量》(GB6566-2001)结束了我国建材标准长期不统一的局面,规定了对建材中放射性实现强制检定的要求,但在装修材料分类、空心材料、废渣利用、测量方法等方面存在着一些不合理的规定,与以往的国家标准相比,对建材中的放射性控制明显放宽,甚至比原来的建材行业标准对石材的控制还要宽,影响了公众的辐射防护安全。对此进行了详细的分析和讨论。
《Limit of radionuclides in building materials》（GB6566-2001） ended the longtime nonuniform phase of the building material standards in China, and prescribed that building materials be coercing examined before sale. However there are some reasonless stipulations about the decorative material class, hollow material, waste residue use and measuring method. Comparison to the past national standards so much as the vocation standard of stone materials, it relaxes evidently the limit of radionuclides in building materials, which impacts the public radioprotection safety indeed. Therefore they are analyzed and discussed in this paper.
