Rezumat:

The method applied to the evaluation of radiation activities implies sample preparation, liquid scintillation cocktail choosing, quench standard curve constructing and implementation, and results verification. We have constructed the quench curve using interpolation method by polynomial spline functions of three degree.
In order to evaluate the measurement efficiencies of tritium activity in simulated liquid scintillation cocktail waste samples quench curve have been used. The results have emphasized that the interpolation method is a very accurate analysis method, and it may be applied to the quantification of radioactivity, using a scintillation liquid cocktail compatible with chemical composition of the analyzed sample.
