摘要

Three synthetic multi-element standards (SMELS-I. II and III), developed recently, have been characterized for their elemental concentration via neutron activation analysis using two research reactors with different neutron flux characteristics. A total of 25 different elements were analysed via gamma-ray spectrometry. The neutron flux was characterized by bare triple monitor method. All the results were within +/- 5% of the reference values except for Zr in SMELS-III. We suggest to use the k(0.Au) and Q(0) values for I-127/I-281 and Cs-133/Cs-134m from another data source.
