Projeto e construção de um castelo de chumbo para proteção radiológica

Abstract

Industrial radiography is a non-destructive test (NDT) that uses X or gamma radiation and is based on the differential absorption suffered by that radiation by virtue of variations in density or thickness of the inspected material or part. Installations where gamma ray sources or X-ray generating equipment are stored and used shall implement a safety system to ensure the protection of members of the public and individuals occupationally exposed to radiation. The use of shielding, distance control and exposure time are the factors used to attenuate radiation to safe levels and prevent irreversible damage from exposure to radiation. This work presents a radiological protection study and deals with the design and preparation by casting of bricks and lead plates up to the assembly of the lead castle for accommodation and safe use of the X-ray generating equipment. The calculations performed for the dimensioning of the structural elements of the lead castle that complements the protection promoted by the barite lined walls of the bunker that houses the X-ray generating equipment where the radiographic tests will be carried out.
