This patent describes a liquid scintillation counter having a counting chamber for receiving a sample containing a scintillator substance and a sample of a radioactive substance to be counted. The improved apparatus positions a radioactive source in an operating location to irradiate the sample in the counting chamber comprising, in combination: (1) a continuous bidirectionally flexible conveyor forming a closed loop for conveying the radioactive source through on operating location and a storage location; (2) means supporting the radioactive source at a position along the flexible conveyor for conveyance; (3) guide means for supporting the conveyor and for guiding conveyor movement along a selected path, the path transversing at spaced positions the storage location for the radioactive source remote from the counting chamber and the operating location for the radioactive source near to the counting chamber; and (4) drive means coupled to the continuous flexible conveyor to draw the conveyor around the path for conveying the radioactive source through the spaced storage and operating locations.
