Special Issue Information

Dear colleagues,

It is a pleasure to introduce you the special issue of the Applied Sciences journal called “Research on the Uncertainty of Radionuclide Characterization”.

The statement of a detailed uncertainty estimation is a fundamental part of every measurement to indicate the degree of confidence assigned to the results and assure their comparison across the globe; radionuclides characterization techniques make no exception thus, the current special issue proposes to explore topics focused on the estimate of uncertainty in radionuclide characterization by addressing strategies to identify, understand and deal with the most predominant components contributing to the dispersion of the results of those kind of analysis.

Specifically, manuscripts considered for submission should include, but not limited to, studies investigating the achievable combined uncertainty related to analytical techniques in which identification and/or quantification of a radionuclide is the key feature, that are used in a broad range of situations, from the routine elemental analysis to dating/safety/forensic inquiries to state-of-the-art traceability transfers. In addition, works concerning studies focused on critical review or redetermination of nuclear parameters such as, among others, decay constants, cross sections, emission probabilities, on which those techniques rely, are also welcomed.

Since uncertainty is a focal point of this special issue, each manuscript should include a detailed uncertainty evaluation, preferably adherent to the prescriptions reported in the Guide to the Expression of Uncertainty in Measurement (GUM) edited by the Bureau International de Poids et Mesures (BIPM).

For accuracy improvement of neutron activation analysis and neutron capture cross sections, bias effects are investigated on g- and s-factors in the Westcott convention. As origins of biases, a joining function shape, neutron temperature, and sample temperature have been investigated. Biases are quantitatively deduced for two 1/v isotopes (197Au, 59Co) and six non-1/v isotopes (241Am, 151Eu, 103Rh, 115In, 177Hf, 226Ra). The s-factor calculated with a joining function deduced recently by a detailed Monte Carlo simulation is compared to s-factors calculated with traditional joining functions by Westcott. The results show the bias induced by the sample temperature is small, in the order of 0.1% for the g-factor and in the order of 1% for the s-factor. On the other hand, the bias size induced by a joining function shape for the s-factor depends significantly on both isotopes and neutron temperature. As a result, the reaction rates are also affected significantly. The bias size for the reaction rate is given in the case of an epithermal neutron index r = 0.1, for the eight isotopes. Full article
