An international research team, including physics from Russia, has created new glasses for protection against X-ray and gamma radiation. Scientists could select new components that improved the characteristics of the samples and allowed to reduce the amount of lead in the glass composition. Physicists engineered several samples of glasses. One of the latest results - glasses based on barium fluoride - was described by the team in the Optic magazine. But the best results have bismuth borate glasses. Its radiation protection characteristics (mean-free-path, half-value layer) are better than commercial analogs. The features of these samples are described in the Scientific Reports.
