摘要：

This article examines the applicability of a newly developed method to standardize C-14 and S-35 mixtures in liquid scintillation spectrometry, which is an unsolved problem in the usual double window method. An improved spectrum unfolding method is applied and the spectral components and activities for C-14 and S-35 computed. Twenty eight assays with activity ratios for C-14 and S-35 between 0.1 and 12 and quench intensities which make the S-35 efficiency vary from 95% to 85% are analysed.
