  • Patent number: 7645506
    Abstract: A radiation protection material for the screening of X- and/or gamma-rays is made from a film-like multi-layer composite material, in which radiation absorbing particles are dispersed. The composite material comprises at least one support layer and a radiation absorbing layer, whereby the radiation absorbing layer comprises a hardening polymeric preparation, which can flow in the working state and with an effective lead content of ?15%.

  • Publication number: 20060230495
    Abstract: A lead-free radiation protection material for use in radiation protection gloves to protect the wearer from scattered secondary radiation comprises at least one layer of a polymeric latex having lead-free radiation absorbing particles and a water soluble polymeric thickener distributed therein. The radiation absorbing particles are lead-free and have a particle size of less than about 10 ?m, and comprise at least one lead-free heavy metal, heavy metal oxide or a combination thereof. The particles are dispersed within the latex at a concentration, by dry weight, sufficient for a sheet having a thickness of about 0.3 mm to block at least about 30% of scattered secondary X-radiation at an intensity of about 60 kV and at least about 20% of scattered secondary X-radiation at an intensity of about 100 kV.

  • Publication number: 20040262546
    Abstract: Proposed is a radiation protection material, especially for use as radiation protection gloves, comprising at least one layer of a matrix material containing natural or synthetic rubber in which, to attenuate the radiation intensity of scattered radiation, radiation absorbing particles are distributed, whereby at least one layer is formed by dipping a pattern in a latex compound of matrix material followed by vulcanisation of the matrix material on the pattern, where the radiation protection material is lead-free and may comprise several successively formed layers and the matrix material compound comprises about 20 to 40% by weight, and more preferably about 33% by weight dry rubber and about 60 to 80% by weight, preferably about 67% by weight of the radiation absorbing particles. This polymeric material may also comprise a small amount of a cellulose derivative in the range of about 0.1 to 0.4%, preferably about 0.25% by dry weight.
