Abstract

A collaboration was initiated to implement the k(0)-NAA standardization method at the BR1-reactor. An important problem with instrumental neutron activation analysis (INAA) is that the quality of the results strongly depends on the matrix activities at measuring time. The procedure often has to be adjusted to the type of sample analysed. The goal of optimization is to give a set of parameters, such as activation time, decay time, measuring time, sample weight, sample detector distance, etc, that yields good analysis performance at a reasonable cost of effort, time and money. A spreadsheet application is developed to predict the gamma spectra to be expected from the sample under given experimental conditions. It provides the analyst with a priori performance evaluations within negligible calculation time, allowing him to search an optimum for the elements of interest.
