Instrumental neutron activation analysis was applied to four reference materials: NBS 1573 (Tomato Leaves), NBS 1645 (Citrus Leaves), NBS 1645 (River Sediment), and IAEA MA-A-2 (TM) (Fish Flesh). The k(0)-standardization method was used. The results are compared with (i) reference values (mostly non-certified) and (ii) published values obtained by other methods. Good agreement is found for most of the elements. For some elements, large discrepancies are observed.
NBS 1573（番茄叶）、NBS 1645（柑橘叶）、NBS 1645（河底沉积物）和国际原子能机构MA-A-2 (TM)（鱼肉）。采用了k(0)标准化方法。将结果与（i）参考值（大多未经认证）和（ii）通过其他方法获得的已发表值进行了比较。发现大多数元素的结果吻合良好。对于某些元素，观察到了较大差异。
