An x-ray radiator for a medical technology x-ray apparatus, has a vacuum chamber arranged in a protective housing, in which is arranged an anode that emits an x-ray beam. The vacuum chamber is surrounded by a protective chamber formed between the protective housing and the vacuum chamber and filled with an electrically insulating liquid. A beam passage chamber filled with a gas is arranged in the protective chamber. The beam passage chamber is traversed by the x-ray beam exiting from the vacuum chamber and propagating toward the protective housing. The amount of secondary radiation generated by the x-ray radiator upon operation is thereby reduced.
