Abstract: A safety system for switching off an irradiation system when the desired irradiation dose has been exceeded, comprises two ionisation chambers through which a particle beam issued from the radiation source propagates, each chamber supplying a radiation monitor. Those monitors supply two parallel connected comparators which operate contact breakers connected in series in a safety circuit controlling the irradiation system.
