  • Radiation shielding material
    Patent number: 4753756
    Abstract: A radiation shielding material prepared by thermally melting a mixture of sulphur and iron oxide powder to react the mixture thoroughly so as to obtain a melt, adding lead oxide granules to the thus obtained melt to mix them together thereby dispersing the former in the latter and then forming the whole mass into a predetermined shape.
