Özet

In this paper, a statistical uranium isotope dilution mass spectrometry approach is presented to simulate the wide range of spike-sample mixed ratios of U-235/U-238, in terms of their related expanded uncertainties and uncertainty budget indexes. To obtain the lowest expanded uncertainty in uranium isotope dilution mass spectrometry (U-IDMS) technique, uranium certified materials of U-CRM 112A (spike) and U-CRM 149 (treated as unknown) are statistically employed and simulated. The simulated data is further applied to project U-IDMS samples by using the "Guide to the Expression of Uncertainty in Measurement (GUM)" software.
