ABSTRACT:
The present invention relates to an X-ray absorbing material that can be used in medicine as well as in the manufacture of special protective clothing, protective screens, housings, protective coatings and isolation materials. In a first embodiment, the material uses as a filler a poly-dispersed mixture, segregated by kneading and containing metallic particles having a size between 10−9and 10−3m, wherein the particles are bonded to the surface of a textile base. The density of the material is defined by the relation qN=(0.01–0.020) qP, where qNis filler. In a second embodiment, the invention uses as a filler the above mixture, although here the particles are surrounded by the volume of a matrix made of a compound that solidifies under atmospheric pressure. The total mass of the poly-dispersed and segregated mixture is defined by the relation M=(0.05–0.5)m, where M is the total mass of the X-ray absorbing poly-dispersed and segregated filler, while m is the equivalent mass of the filler material that is equal in protective properties to the mass M. In a third embodiment, the invention uses as a filler the above mixture with the particles bonded to an intermediate substrate consisting of a textile base and surrounded by the volume of a matrix.
