Zusammenfassung:This simple calibration equipment consists of two or more 137Cs line radiation sources having equal activities and a lead-shield vessel. The sources are placed symmetrically within the vessel. The purpose is to have uniform exposure rate in the center of vessel where a GM probe is inserted. Its features are efficient calibration and reduction of personal exposure for workers.
