Specialists from the Ural Federal University (UrFU), together with foreign colleagues, have developed new materials that effectively protect against radioactive radiation and are safe for the environment.
The created materials consist of natural clays, glass production waste, and a small amount of boric acid. After grinding, pressing under a pressure of about 114 MPa, and firing at 550°C, a durable ceramic is obtained that can shield gamma radiation — one of the most dangerous types of radiation. The addition of glass increases density and mechanical strength, and also solves the problem of industrial waste disposal.
The resulting samples can be used in the construction of X-ray rooms, radiation-hazardous facilities, and storage facilities where moderate protection is required without the use of lead. This metal is traditionally used for radiation protection, but it is toxic and poses a threat to human health and ecosystems.
The need for such materials is growing rapidly. The reason is the expanding use of radioactive substances in medicine and the construction of new nuclear reactors. Scientists are also exploring the possibility of using local mineral raw materials in the construction of nuclear power plants to reduce construction costs and dependence on imported components.
