<p>The invention concerns a material designed to construct rigid and resistant structures protecting against radiation used in particular in the medical field to protect operators against contamination and exposure to radiation (X-rays in radiology, radioactive products in nuclear medicine ). Said construction material is in the form of a complex of at least two stacked plates, one (2) made of lead and the other (3, 4) of resin (methyl polymethacrylate, polyester resin, epoxy resin ) containing a filler adapted to enhance its mechanical resistance properties, said plates (2, 3, 4) being prepared beforehand independently of each other and being bonded together.</p> |
