title: Counting efficiency of some commercially available liquid scintillators compared.
abstract: We investigated four commercially available liquid scintillators as to overall counting efficiency and quenching effect of added phosphate-buffered isotonic saline. They differed significantly in these respects. Evidently, characteristics of the scintillator used in radioimmunoassays where beta-particle emitters are counted should be carefully examined if results are to be optimal.
