建筑材料中放射性物质限制标准的若干建议

The suggests about standard of limit on radioactive substance in building materials

对于建材中放射性物质的限制,建议制订统一的国家标准,适当降低226Ra的限制值,对用于建材生产的工业废渣本身也应该进行比活度限制,对超过限值的产品必须从严控制。

The government drew up three standards to limit the radioactive substances in building materials. Their limiting volumes are basically alike, but there are some differences in carrying out the standards, which can even endanger them. About limitation of the radioactive substances in building materials, suggestions are advanced which are to unify the standards, to low down the 226Ra limiting volume, to limit the radioactivities of industrial waste slags used in building materials , to strictly manage the products which exceed the limiting volumes and to force to measure their radionuclide contents before they are sold.
