Popis:	The usefulness of radiotracers for flow studies is extended into the shorter time range. Thus the residual contamination problem associated with long life isotopes is minimized. The separation of gamma-emitting barium-137 from its parent cesium-137 by resin exchange permits the frequent separation and injection of a sharp pulse of the short half life (2.6 minutes) Ba/sup 137/ using an automatic device known as the gamma milker. The penetrating gamma rays of the tracer are measured by scintillation detectors mounted on the external surface of the process vessel thus eliminating the need of removing samples for subsequent analyses. High speed recording equipment permits the measurement of pulse responses ranging from a few tenths to 100 seconds.
