The Problems of Liquid Scintillation Spectrometry in Modern Conditions. Scintillation Cocktail

The main problems of liquid scintillation spectrometry in the current modern conditions are presented. The possibility of working on LC radiometers using scintillation cocktails created on the basis of reagents available in Russia was analyzed. Comparative results of testing model radionuclide mixtures in proprietary (UltimaGold AB, INSTA-FLUOR) scintillation cocktails and those prepared in laboratory conditions based on the aromatic solvent toluene (xylene) are shown.
