Zusammenfassung:	The invention provides a method and apparatus for facilitating calibration o f a nuclear gauge by automating the movement of a source rod between a plurali ty of source rod positions. The apparatus can include a linearly moveable membe r, such as a threaded rod, a motorized linear actuator, such as a stepper motor , and a source rod grip attached to the linearly moveable member for affixing the source rod to the member.
