Optimization of the double isotope dilution
Résumé
The double isotope dilution is a powerful methodology to measure accurately the ratio between two isotopes of two different elements (e.g. 238Pu/238U, 148Nd/238U or 230Th/238U ratios). To obtain the lowest possible uncertainty, some parameters must be optimized: the elaboration of the spike and the proportion of the spike in the sample - spike mixture. A piece of code is provided to easily calculate the optimal parameters. As an example, the application of the code to 238Pu/238U and 148Nd/238U ratios determination in irradiated sample will be discussed.
