Study of the influence of the LS-cocktail composition for the standardisation of radionuclides using the TDCR model.
The influence of the LS-cocktail on the value of the ionisation quenching kB factor was investigated. Sets of 3H and 63Ni standard sources in some commercial and home-made scintillators of different compositions were prepared and measured using the TDCR method. The Birks kB factor was determined for each LS-cocktail and the results are discussed. A model of anisotropy of the triple counter caused by PM-tubes defocusing was applied for calculation.
