Performance comparison of experimental liquid scintillation cocktails

Popis výsledku v původním jazyce

In this article the properties of four new luminophores, from the group of bifluorenes and other substances with multiple aromatic rings, were measured and studied for possible use in liquid scintillation, namely 1-phenyl-3-(2,4,6-trimethyl-phenyl)-2-pyrazoline, 2,2′,7,7′-tetrakis(N,N-diphenyl-amino)-9,9′-spirobifluorene, 2-(4-biphenylyl)-6-phenylbenzoxazole and 9,9′-bifluorenyl. The measurement was also done for the most commonly used luminophore (2,5-diphenyloxazole (PPO)). To improve counting efficiency the wavelength shifters were added to scintillation cocktail in particular POPOP and bis-MSB. The main effort was focused on the determination of sample counting efficiency of experimental cocktails using radionuclides Am-241, Sr-90 and H-3, especially for acidic, alkaline and neutral water solutions. The results were compared with the commercially used Aqualight scintillation cocktail.
