Beta spectrum analysis: a new method to analyze mixtures of beta-emitting radionuclides by liquid scintillation techniques

摘要

A description is given of a method to couple a liquid scintillation spectrometer to a multichannel pulse-height analyzer to record beta spectra simultaneously with three different energy ranges. Spectra of tritium, carbon-14 and phosphorus-32 recorded by this method are presented. Analyses of the beta spectra are performed by a least-squares technique, and the results are shown in tabular form.
