    All blood, plasma, urine, and fecal samples were assayed for total radioactivity by liquid scintillation counting (LSC). Quench corrections were made by the external standard method. For liquid .   Purchase Organic Scintillators and Scintillation Counting - 1st Edition. Print Book & E-Book. ISBN , Book Edition: 1.

    Urine, distilled in the presence of toluene, is assayed for tritium content by a liquid scintillation technique. Two 1-in. diameter matched E.M.I. type S/A photomultiplier tubes are connected through coincidence and discriminator units to a standard amplifier and scaler. The liquid scintillation counting .   The tritium-in-urine (HTO plus OBT) was measured by liquid scintillation counting. The doses of tritium-in-urine from participants living at 2, 10 and 22 km were in a range of – Cited by: 4.

    To estimate the tritium doses of the residents living in the vicinity of a nuclear power plant, urine samples of 34 adults were collected from residents living near the Qinshan nuclear power plant. The tritium-in-urine (HTO plus OBT) was measured by liquid scintillation counting. The doses of tritium-in-urine Cited by: 4. Due to the extremely low energetic β-radiation liquid scintillation is the only measuring technique with satisfying counting efficiencies from 40 to 70 %. After sampling, the water sample has to be well sealed for the transport (H-T-exchange!). The sample is purified by distillation and then measured as gel by liquid scintillation.

Liquid scintillation counting of tritiated water in plasma following dioxane precipitation. The International Journal of Applied Radiation and Isotopes27 (2), DOI: /. Rapid determination of gross alpha and beta emitters in urine by liquid scintillation counting is discussed.

This method is based on direct addition of urine into scintillation cocktail. ²⁴¹Am. Liquid scintillation counting (LSC) is a major technique not only for measurement of pure beta emitting radionuclides, but also radionuclides decay by electron capture and alpha : Xiaolin Hou.

The spillover from beta to alpha spectrum is Thorium determination by liquid scintillation smaller than 1%. Radioactive equilibrium between Th and daughter products is reached after two weeks. As the Th spike used here also contains traces of the a-emitting Th isotopes, the blank value in the aspectrum, and therefore also the lower limit of detection Cited by: 4.
