Scientists from South Ural State University (SUSU) have proposed a new alternative to lead for protection from radiation. According to RIA Novosti, the material they have created can be used to make glass, which can be protected in industries where radioactive radiation is used. Research by Russian scientists has been published in the journal Optical Materials.
In medicine, in particular, in oncology, radiation therapy is used to treat malignant tumors. In order to protect the patient, as well as medical personnel and equipment during irradiation, use protective screens, helmets and glasses made of special glass, which contains lead – a heavy, toxic metal. Scientists have created a material based on a compound of oxides of strontium, boron and tellurium dioxide. It has shielding properties, can shield gamma rays and thus replace lead.
Lead is a very dangerous substance, therefore, in many countries of the world, its use in various industries is being tried to limit, and scientists continue to look for an alternative to it. The new material is highly efficient. Adding it to the glass increases the density, which is very important in protecting against radiation. In addition, the production technology is quite simple and relatively cheap, it allows you to create glasses of different shapes and thicknesses and, at the same time, significantly save on expensive raw materials.
Scientists believe that their development will be useful not only in medicine, but also in the nuclear, aerospace industries, as well as in other types of human activities.
