Liquid scintillators with advanced scintillation characteristics
Instruments and Experimental Techniques, 2010Results of studying the influence of the component composition of liquid scintillators on their scintillation properties are presented. The correlation between the energy resolution and the peak-to-valley ratio in β-ray spectra is discussed. Compositions of fire-safe scintillation systems with characteristics above the generally accepted standard are ...

Chemiluminescence in liquid scintillation counting
Analytical Biochemistry, 1970Abstract A new chemiluminescence reaction arising from the combination of trichloroacetic acid and bathophenanthroline during the liquid scintillation counting of the Fe 59 beta emission is described. This is compared to the previously reported chemiluminescence arising from a reaction between quarternary amines and peroxides.

A new scintillator for liquid scintillation counting
The International Journal of Applied Radiation and Isotopes, 1967Abstract This report describes the results of investigations carried out with a new scintillator: 2-(4′-t-Butylphenyl)-5-(4″-biphenylyl)-1,3,4-oxdiazole (Butyl-PBD). Counting efficiencies and background counts of variously quenched toluene and dioxane systems containing Butyl-PBD have been compared with similar systems containing PPO and DM-POPOP as ...

Relative light yield of liquid scintillator and gadolinium-loaded liquid scintillator
Journal of Radioanalytical and Nuclear Chemistry, 2015Relative light yield of linear alkyl benzene (LAB)-based gadolinium-loaded liquid scintillator (GdLS) and LAB-based non-gadolinium loaded liquid scintillator (LS) is an important parameter of the GdLS antineutrino detector, which was developed and applied to precisely measure the neutrino oscillation parameter in the current reactor neutrino ...

New emulsive scintillator for liquid scintillation measurements
International Journal of Radiation Applications and Instrumentation. Part A. Applied Radiation and Isotopes, 1989Abstract A new emulsive scintillator for liquid scintillation measurements has been proposed, which removes the inherent disadvantages of conventional emulsive scintillators. The new scintillator never forms gels and two phases, both of which are very inconvenient for user, and maintains a state of soft sol within a water content from 0 to 50%.

Liquid scintillation counting of blood
The International Journal of Applied Radiation and Isotopes, 1965Abstract Several methods are compared for liquid scintillation counting of blood samples. The radioactive products are extracted from the blood either directly with the scintillation solvent system “Polyether 611” or with solvents such as dioxane or ethanol. The last-mentioned extracts are counted in a hyamine-Cl-touluene system. Blood contacted with

Liquid scintillators—III the quenching of liquid-scintillator solutions by organic compounds
The International Journal of Applied Radiation and Isotopes, 1957Abstract A study has been made of the quenching characteristics of a large number of selected organic compounds in a few commonly encountered liquid scintillator solutions. From this it should be possible to anticipate the quenching difficulties associated with homogeneous liquid scintillation counting.

Medicinal paraffin as a solvent for liquid scintillators offers the advantages of low cost, high flash point, and no deleterious effects on perspex containers. The light output of medicinal paraffin containing 3 g/l PPO and 0.02 g/l POPOP was found to be 28% of that of toluene containing the same scinitillator concentrations.
