Tritium Assay by Liquid Scintillation Spectrometry

Tritium assay by liquid scintillation spectrometry. Comparison of tritium and deuterium oxides as tracers for body water.

ISIDORE S. EDELMAN, M.D. TO DATE, deuterium oxide (D20) has been the most satisfactory and accurate tracer substance for body water: its diffusion characteristics have been thoroughly studied, and its reliability as a tracer for body water by the dilution technic has been established.' 2 However, the technical difficulty of deuterium analysis by the falling drop method and the labor and expense...

The assay of tritium-labelled folate in faeces by the oxygen flask combustion technique followed by liquid scintillation counting.

The assay of tritium-labelled substances in faeces requires conversion of tritium into either tritium gas (Payne and Done, 1958) or tritium-labelled water. Belcher (1961) and Kremenchuzky, Musso, Hoffbrand, and Viola (1967) used wet oxidation of faeces followed by liquid scintillation counting, while Burns and Glass (1963) used dry oxidation in a bomb calorimeter. There is a need for a reproduc...

Tritium Determination in Danube River Water in Serbia by Liquid Scintillation Counter

Tritium activity concentration in Danube river water in Serbia has been determinate using a liquid scintillation counter Quantulus 1220. During December 2010, water samples were taken along the entire course of Danube through Serbia, from HungarianSerbian to Romanian-Serbian border. This investigation is very important because of the nearness of nuclear reactor Paks in Hungary. Sample preparati...

Some Factors Affecting Alpha Particle Detection In Liquid Scintillation Spectrometry

Pulse shape analyzers have been introduced in commercial liquid scintillation counters, such as the WaIlac 1220 QuantulusTM and 1219 SM, enabling separation of alpha particle spectra from other types of radiation in a single measurement and making ultra sensitive alpha counting possible. Background count rates as low as one count per day for 214Po in a teflon vial are achievable while still ret...
