Abstract: A bidirectional device for changing a handling glove from inside to outside and from outside to inside a glove box under containment. The device is intended to replace a used glove (60) with a new glove. It includes a cuff (6) sealingly connected to a cuff sleeve (20) and a glove (60) of a flexible material sealingly connected to a glove sleeve (40). The glove sleeve includes externally clip-on contacts and the cuff sleeve includes bayonet type helical ramps (30). The clip-on contacts of the glove sleeve slip in the helical ramps of the cuff sleeves until the glove sleeve is latched forming, once assembled, a sealed whole called a wrist ring (10).

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.

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.
