Scientists at the Ural Federal University (UrFU) with colleagues from the Arabian Peninsula have improved the radiation protection properties of glass, in particular borate glasses (boron oxide-based glass). They introduced special additives into the basic composition of the glass—heavy metal oxides. This significantly increased the density of the material without affecting its transparency. A description of the experiments and the results of the study was published in the journal Progress in Nuclear Energy.
