Principle of the α–β coincidence method The α–β coincidence method was developed by one of the authors for the low-level 222Rn measurement (Noguchi & Wakita, 1975). The method is based on the coincidence counting of two radiations emitted successively in a short time interval. Fig. 1...
Activity measurements by LSC methods require the radioactive sample to be dissolved in a scintillation cocktail. This generally ensures high detection efficiency as the ionizing particles are emitted directly in the cocktail. However, the addition of solutes to the cocktail may be a source of sample...

(14C or 125I). In this case, the determination of the quantity of antibiotic present or otherwise in the milk necessitates the use of a special instrument such as a scintillation counter, for example. In addition, handling radioactive products even in very small quantities is not completely ...
Aliquots of the perfluorocarbon liquid were removed at intervals and the radioactivity measured with a scintillation counter. After 120 minutes the cells were tested for membrane integrity with a vital dye, and the membrane and cells were found to be viable, for further reference on the biological...
Compton efficiency tracingTritiumThe principle of the Compton source efficiency tracing method (CET) in liquid scintillation counting (LSC) is to use, as a tracer, a Compton electron source temporarily created inside the source being measured. The tracer source and the source to measure have thus ...
About 110 Mbq of 137Cs is used as a γ-ray source of 662 keV and a NaI scintillation counter is used as a γ-ray detector. Ge2Sb2Te5 specimen is sealed in an ampoule made of fused quartz with a diameter of 1.1 cm and a length of 2.388 ± 0.002 cm. The ...
