| description | Stínicí kompozitní stavební materiály pro stavební prvky, které jsou na bázi kameniva, cementu a vody nebo na bázi kameniva a epoxidové pryskyřice, mají hmotnostní aktivitu v nich obsažených radionuklidů pro radionuklid Ra-226 nižší než 5 Bq/kg, pro radionuklid Th-228 nižší než 5 Bg/kg a pro radionuklid K40 nižší než 50 Bg/kg. Kamenivo a nerostné složky cementu jsou přitom tvořeny materiály z prvohorních geologických formací.
In the present invention, there are disclosed screening composite building materials for building elements based on aggregates, cement and water or based on aggregates and epoxy resin, having specific activity of radionuclides comprised therein for the Ra-226 radionuclide lower than 5 Bq/kg, for the Th-228 radionuclide lower than 5 Bq/kg and for the K40 radionuclide lower than 50 Bq/kg. At the same time, aggregates and cement mineral components are comprised of materials of geological Paleozoic-formations. |
