Abstract
In the illustrated embodiments a logical switching member is energized from a common power supply at the time that a manual switch is actuated for initiating an x-ray exposure. If the logical switching member does not receive an inhibiting signal within a definite inhibition interval less than a minimum exposure time, the switching member reaches a normal operating state and supplies its logical output signal to turn off the x-ray source. The inhibiting signal is not generated if the radiation detector fails to receive radiation from the x-ray source, or if there is a circuit failure in the inhibiting signal generating circuitry connected to the input of the switching member, or if the dosage fails to increase at least at a selected minimum rate during the inhibition time interval.
