How to calculate uncertainties of neutron flux parameters and uncertainties of analysis results in k0-NAA?

A novel method is presented for the calculation of uncertainties of neutron flux parameters and element mass fractions and their uncertainties in k(0)-neutron activation analysis (k(0)-NAA) using the Kragten universally applicable spreadsheet technique. The results obtained are compared with other approaches for evaluation of uncertainties of the neutron flux parameters and element mass fractions, namely with the Kayzero for Windows, k0-IAEA and ERON programs. The differences observed are discussed in terms of how the above programs take into account various uncertainty sources and their correlations.
