An x-ray diagnostic system having an image intensifier television chain includes sensors for respectively monitoring the presence of x-radiation from an x-ray tube, the presence of light at the output of an x-ray image intensifier, and the presence of a video signal corresponding to the x-ray image. Each sensor supplies an electronic signal to a safety circuit which is connected to the high voltage generator for the x-ray tube. If, after the presence of x-radiation is detected, no light and/or no video signal is detected, the safety circuit automatically disconnects the x-ray tube from the high voltage generator.
