Eight neutron activation analysis research groups from seven countries have participated in a trial proficiency test under the auspices of the Forum for Nuclear Cooperation in Asia. Three stream sediment reference materials were used in the test. A high degree of proficiency was found in the quantification of Co and Sc and more than 20 elements were well quantified by the majority of laboratories. The results support the use of neutron activation analysis, as practised by the participants, for geochemical mapping. The data produced in this study may provide an opportunity to improve the characterisation of the three reference materials.
