The Universal Dose Calibrator is a standard machine for individual calibration and verification of gamma radiation measurement instruments.
It consists of a number of gamma radiation sources, located in a carrousel, shielded by a lead castle. The heart of the calibrator is an industrial PLC, used to control source manipulation, trolley displacement and an extended set of safety precautions. The operator console gives direct access to the dose calibrator for interactive operation. It displays the requested source, the source in irradiation position, the irradiation time and the source-trolley distance.
