The Ultra-Low Background Liquid Scintillation Counter
developed by Pacific Northwest National Laboratory will expand the
application of liquid scintillation counting by enabling lower
detection limits and smaller sample volumes. By reducing the
overall count rate of the background environment approximately 2
orders of magnitude below that of commercially available systems,
backgrounds on the order of tens of counts per day over an energy
range of ~3-3600 keV can be
realized. Initial test results of the ULB LSC show promising
results for ultra-low background detection with liquid
