X-RAY ABSORBING MATERIAL AND VARIANTS

摘要

The present invention relates to an X-ray absorbing material which can be us ed in medicine as well as in the production of special protection clothes, protection screens, housings, protection coatings and isolation materials. In a first embodiment, the material uses as a filler a poly-dispersed kneading-segregated mixture containing metallic particles having a size of between 10 -9 and 10 -3 m, wherein said particles are bonded to the surface of a textile base. The density of the material is defined by the relation q N = (0.01 - 0.20)q P where q N is the density of the X-ray absorbing material as a whole while q P is the density of the material used for the particles of the X-ray absorbing filler. In a second embodiment, this invention uses as a filler the above- mentioned mixture though 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 ma ss of the X-ray absorbing poly-dispersed and segregated filler, while m is the equivalent mass of the filler material which is equal by its protection properties to the mass M. In a third embodiment, this invention uses as a filler the above-mentioned mixture thou gh the particles are bonded to an intermediate substrate consisting of a textile base and surrounded by the volume of a matrix.
