<p>Metal absorbers for nuclear radiations contain metallic gadolinium in the form of a metal alloy chosen from at least one of the following classes of alloys: copper-gadolinium, and magnesium-gadolinium, respectively, each of the said classes of alloys containing from 0.05% to 95% by weight of gadolinium relative to the total weight of the alloy. They may additionally contain additional elements such as neutron-absorbing elements, elements which reinforce the physical, mechanical and technological properties, fibres or anticorrosion elements. They can be employed especially for absorbing neutrons and gamma and X radiations.</p> |
