Abstract
The U.S. Geological Survey has recently modified the Tracerlab Automatic Sample Changer so that the geometry is greatly improved for counting larger low-activity samples in finely ground form. The larger sample and larger Geiger Mueller tubes allow a greater number of samples to be counted per hour with the same statistical accuracy.
