Abstract

The k(0)-standardization method, the present state-of-the-art of which is shortly reviewed, is applied to multi-element reactor neutron activation analysis of (standard) reference materials. The analyses are performed independently at the Institute for Nuclear Sciences (Gent, Belgium) and the Central Research Institute for Physics (Budapest, Hungary). Results are given for USGS G-2 (granite), NBS SRM-1633a (coal fly ash) and FCG (fired clay of Gent). Comparison with literature data shows that the k(0)-method, while being experimentally simple, versatile and suited for computerization, offers a potential accuracy of better than 5%.
