Abstract

The paper presents the results of a comparative study of the characteristics of a foreign liquid scintillation cocktail «Ultima Gold AB» from Perkin Elmer (USA) and a domestic scintillation cocktail «LIRA-1» developed by VNIIRAE specialists (Obninsk). The possibility of using the «LIRA-1» scintillation cocktail as an analogue of the «Ultima Gold AB» cocktail during liquid scintillation spectrometry of tritium is shown.
