Scientists from South Ural State University in Chelyabinsk have created a new material: based on it
Develop high-quality and non-toxicRadiation protection equipment is important, for example, for doctors who administer radiation therapy. Today they use screens, helmets and glasses made of special glasses for protection, but they often contain toxic lead: it is not safe to work with and difficult to dispose of.
Experts around the world continue to search for a suitable material that will effectively protect against radiation.
We have proposed a fundamentally new material,which can replace lead and have been shown to be capable of effectively shielding gamma rays. Strontium-borate-tellurite glasses have both high density and effective atomic number. Strontium oxide is also a heavy metal oxide, and if added to glass, it will increase the density of the material, which is an important parameter in radiation protection.

Based on a chemical compound of oxidesstrontium and boron, as well as tellurium dioxide (SrO – B2O3 – TeO2), SUSU scientists have created a material from which it is possible to make lead-free protective glasses.
Protection against ionizing radiation is needed not onlyin medicine, but also in nuclear, aerospace and scientific activities. For example, you can make radiation protective glasses, helmets, windows, portholes, screens and mount them in walls.
