Quenching Correction in Liquid Scintillation Counting
1966Two types of quenching are encountered in liquid scintillation counting, chemical and color quenching. Chemical quenching is caused by the presence of nonfluorescent molecules in the liquid scintillator system which interfere with the energy transfer between the solvent and the organic scintillator.

Using Cellosolve as a solubilizing additive, up to 5.84 ml of aqueous bicarbonate solutions and essentially equivalent amounts of urine and plasma containing carbon-14- sodium carbonate can be assayed by liquid scintillation counting techniques.

Liquid scintillation counting of carbon-14 and tritium in blood, heart, kidney, liver, spleen, lung, and muscle tissue was investigated. The dissolution of tissues into two different solvent systems and their counting are discussed.

Liquid scintillation counting of tritiated water
The International Journal of Applied Radiation and Isotopes, 1960The performance of single photomultiplier and twophotomultiplier coincidence systems for counting of tritiated water were investigated for comparison. The factors contributing to the background and ihe effects of long- lived scintillator phosphorescence are discussed. The counting efficiencies of the two systems were determined. (D.L.C.)

Liquid Scintillation Counting of Tritium
1963The intensive development of the liquid scintillation counter for the measurement of tritium has come about in response to a need for a sensitive, reliable, and simple counting method for this difficult-to-measure nuclide. A number of groups participated in this development, but the workers at Los Alamos deserve special mention [1, 2]. Our own work [3]

Standardization of tritium by liquid scintillation counting
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1992Abstract The activity of 3H samples has been measured by liquid scintillation counting using a system with two independent phototubes and including corrections due to the atomic excitation energy subsequent to beta decay and using Voltz's quench correction formula with a kB value of 0.0081 cm/MeV, experimentally fitted. An overall uncertainty of 1.29
