One of the most appreciated advantages of neutron activation analysis (NAA), being a primary method of measurement, is its potential for accuracy and the possibility to provide a complete uncertainty budget of the results. For this reason, NAA has an indispensable role in certification of element mass fractions in reference materials (RMs), especially at very low levels. Not less important...

One of the main difficulties in quantitative analysis using the PGAA technique is the large number of peaks detected in the prompt-gamma spectra. It needs a comprehensive database containing the energy and cross section information for all the elements enabling the identification of the different elements.

Analysis of spectra in PGAA is a well-developed method with, in principle, straightforward data treatment. However, the large number of emitted gamma rays, interference of the gamma rays from different elements and the specific relative ratio of elements in the sample can make the process of analysis time consuming. Even with experts analyzing the data, the analysis in some cases can get...
