Determination of Liquid Scintillation Counting Efficiency by Pulse-Height Shift

  • L. A. Baillie


A method has been developed by which liquid scintillation counting efficiency can be determined simultaneously with the count. The two scalers of a liquid-scintillation spectrometer are set to count simultaneously different parts of the spectrum. The ratio between the counts on the two scalers can be used as an accurate index of the counting efficiency on one of them. This method saves considerable time compared with the conventional internal-standard method and appears to be of equal or greater accuracy.
