Ponzi Automatic doors with RX shields delimit hospital areas with exposure to X-rays: analysis laboratories, plaster room, radiodiagnostics, TAC room, nuclear medicine, radiotherapy and dentistry, operating sectors. Ponzi provides a wide range of solutions, as the environment and the hospital layout require different types of intervention. The application of the RX shielding is therefore referable to a wide range of doors, from the sliding operative ones to a single hermetically sealed door, and from the simple AST sliding type for diagnostics, analysis laboratories and hot rooms, to hinged door with one or two doors for the radiological room. The purpose of radiation shielding is to limit the exposure of workers and the public to an acceptable level. Ponzi doors have a 1 - 2 mm lead shielding. At full height, from floor to ceiling, guaranteeing a solution of continuity to the wall. The Anti - X visuals are composed of a crystal with lead equivalence and are inserted in a frame with a lead foil interposed. All in all, it must guarantee a stability result with the wall, therefore avoiding any leaks of radiation.
