Which component is primarily responsible for protecting and grounding high-voltage components?

The metal housing is the main safeguard for high-voltage parts. It encloses the X-ray tube and the high-voltage circuitry, providing physical protection and acting as a radiation shield. Importantly, it is bonded to the building’s grounding system, so any stray current or charge from the high-voltage components is directed safely to earth. This grounding keeps the housing at earth potential and helps prevent electric shock to the patient and operator, while also helping to minimize leakage radiation escaping the unit. The other parts don’t perform this combination of shielding and grounding—the X-ray tube itself sits inside the housing, aluminum disks are not the grounding/shielding shell, and the control panel handles operation rather than protection or grounding.
