The International Atomic Energy Agency (IAEA) implemented an innovative project for assisting neutron activation analysis laboratories in improving the validity of their results by feedback workshops for discussion of results from participation in interlaboratory comparisons rounds in 2010. The participants learned during these meetings to identify the most probable sources of errors in their analytical procedures and how to implement corrective actions to prevent reoccurrence. The outcome of successive rounds between 2010 and 2018 is discussed and experiences during the feedback workshops are given. The quantitative evaluation of the results shows an overall improvement in satisfactory performance. Moreover, there is a clear indication that improvements are consolidated in most laboratories but also stimulate laboratories to develop to a higher level of excellence. Regional differences in performance are also analysed.

国际原子能机构 (IAEA) 实施了一个创新项目，通过反馈研讨会来帮助中子活化分析实验室提高其结果的有效性，以讨论 2010 年参与实验室间比较轮次的结果。与会者在这些会议上了解到，以确定分析程序中最可能的错误来源以及如何实施纠正措施以防止再次发生。讨论了 2010 年至 2018 年连续几轮的结果，并给出了反馈研讨会期间的经验。对结果的定量评估显示了令人满意的性能的整体改进。而且，有一个明确的迹象表明，大多数实验室的改进得到巩固，但也刺激实验室发展到更高的卓越水平。还分析了性能的区域差异。
