Which component of the x-ray tube construction is responsible for minimizing leakage radiation?

The tube housing is a critical component of the x-ray tube construction that is specifically designed to minimize leakage radiation. It serves as a protective outer casing that surrounds the x-ray tube and helps contain the radiation produced during the imaging process. This housing is typically made of dense materials, such as lead, which effectively absorb and prevent stray radiation from escaping into the surrounding environment. By controlling and minimizing leakage radiation, the tube housing not only ensures the safety of personnel and patients but also complies with regulatory standards concerning radiation exposure.

Understanding this role highlights the importance of proper equipment design in ensuring radiation safety and protection in medical imaging environments. The other components, while essential to the overall operation of the x-ray tube, do not primarily function to control leakage radiation.
