This multi-layer film web is suitable for shielding against X-rays, but not as a stable, flexible X-ray protective material in the form of an X-ray protective apron in accordance with DIN - 6813. From OE 41 31 2?4 A 1 a radiation-absorbing plastic web made of highly molecular polymers with radiation-absorbing additives, in particular rare earth metals in the form of organometallic compounds or as salts of organic origin, is known. This invention attempts to solve the problem of neutralizing corpuscular particles with an energy in the range of 0.1 MeV to 2 MeV. These energy ranges are not found in any conventional X-ray rooms for diagnostic purposes. The radiation protection material described under DE 41 31 274 A can be processed into a comfortable, flexible X-ray protection apron with a specified thickness of 3 mm and a SHORE A of K3. 8?3*S of 19« 11.93 it is possible to produce a gamma-ray absorbing, light, comfortable to wear, soft and flexible X-ray protection material which, in addition to having rubber-elastic properties, also meets the DlM *- standard 6813JRADIATION PROTECTION ACCESSORIES FOR MEDICAL APPLICATIONS VDM X-Rays up to 300 KV (July 15, 1993).

The absorption of strata is considerable and can be achieved by applying different recipes with different densities)! The invention, as characterized in the patent claims, solves the problem by mixing carbide and its oxides, such as bismuth, tungsten and lead, as mixtures in the form of powders with a grain size of less than 50 microns very homogeneously in a conventional CIRCULAR DISPLAY with a PW ·* PLASTISOL.

Furthermore, basic physical properties such as softness and flexibility are increased. The common natural rubber slai rubber has a SHORE A hardness of 60, the X-ray protection material on which this invention is based has a controllable SHORE A hardness of 35 - 45. The BLEXVXWL can also be produced with a Shore hardness of 3D 40 by using the appropriate Welchmacfoer content, "however, the ageing resistance is greatly impaired by the volatility of the plasticizer." In contrast to natural rubber vulcanization, where depending on the degree of hardness up to 5 - 12 % sulfur additions are possible, the sulfur addition can be reduced in the case of The sulfur content of the butadiene/acrylic copolymer synthetic material can be described as a trace element in relation to the sulfur formulation. The known skin allergies caused by a high sulfur content in natural rubber can therefore be ruled out. In the present invention, different densities can be produced by using multiple layers, at least two layers, which in turn have an increased absorption effect on nuclear radiation and the resulting scattered radiation. By modifying the formulation in the surface layers, properties such as surface abrasion resistance, for example, can be specifically improved.

According to DIN standard 6813 (July 1983, drawn up by the Radiology Standards Committee of the DIM German Institute for Standardization in association with the German X-ray Association ) , radiation protection accessories such as radiation protection aprons, radiation protection (surgical aprons, patient protection aprons, duct protection), radiation protection curtains, etc. can be made from the multilayered, flexible X-ray protection material. Depending on the regulation and the thus specified lead equivalent value or degree of radiation attenuation, the X-ray protection material according to the invention can be made in one or more layers to form a Radiation protection aprons can be made»
