METALLIC MODULES AND ASSEMBLY SYSTEM FOR THE FORMATION OF SHIELDED WALLS, FLOOR AND CEILING FOR ROOMS USED FOR RADIOTHERAPY

The inventor has developed a pair of modules which consist of metal blocks filled with metal powder, preferably iron ore, in such a configuration to enable several units of these modules to be fittedtogether and welded, quickly and simply, for the formation of a wall, floor or ceiling with high radiation attenuation capacity and considerably less thickness when compared to concrete walls constructed for the same purpose. Thus, the walls formed by these modules are easy to construct, by the assembly, and do not have cracks, holes or fragmentation. This way, even when used for repair or strengthening of the radiotherapy area or room, the interdiction will not be necessary for long periods of time. The material with which the modules are manufactured guarantees its low cost. Thus, even whenmodules manufactured in a larger size are used, in order to increase the shielding capacity of the wall, there is a big cost reduction on the project, especially compared to steel plates and, especially lead, ensuring the same
