  • Patent number: 9029817
    Abstract: A radiation attenuation elastomeric material which includes an elastomer in which a powder of metal oxides is dispersed, wherein the powder of metal oxides includes from 70 to 90% by mass of bismuth trioxide, from 5 to 15% by mass of tungsten trioxide, and from 5 to 15% of lanthanum trioxide. Multilayer protective gloves incorporating this material are suitable for use in protecting a wearer from ionizing radiation when handling radioactive materials.

  • Publication number: 20120217423
    Abstract: The invention relates to a radiation attenuation elastomeric material of the type comprising an elastomer in which a powder of metal oxides is dispersed, and which is characterized in that the powder of metal oxides comprises from 70 to 90% by mass of bismuth trioxide, from 5 to 15% by mass of tungsten trioxide and from 5 to 15% of lanthanum trioxide. It also relates to the use of this elastomeric material for making individual protective articles against ionizing radiations. It further relates to a multilayer protective glove against ionizing radiations, at least one layer of which is formed by said elastomeric material, as well as to the use of this glove for protection against ionizing radiations emitted by powders of nuclear fuels, notably with plutonium. Fields of application: the nuclear industry for handling powders of nuclear fuels but also medical imaging, interventional radiology, nuclear medicine, processing of plastic materials, inspection and control of manufactured parts, etc.

  • Publication number: 20040078867
    Abstract: The invention concerns a glove having high mechanical performance, and high resistance to chemical products and/or radiolysis, characterised in that it comprises one or several elastomer layers, identical or different, obtained from solutions of said elastomers in one or several organic solvents or in water, said layers being reinforced, on one or several parts or on the entire internal surface of the glove, with a fabric with high mechanical strength. The invention also concerns a method for making said glove and its uses.
