反应堆中子活化分析(NAA)是近年来迅速发展的核分析技术,由于该方法取样量少、快速、准确、灵敏度高、具有多元素同时分析等优点,适合于生物样品中微量元素的分析研究。实验中,如果感兴趣的元素很多,往往要全面考虑到各个待测元素的放射性核素,选用合适的中子通量和辐照时间、衰变时间、计数时间。在这种情况下,正确合理选择最佳化实验条件是十分重要的。传统的方法是通过反复实验尝试和误差方法来取得,这将变得非常费时费
The reactor neutron activation analysis (NAA) is a rapidly developing nuclear analysis technique in recent years. Due to its low sampling volume, fast, accurate, high sensitivity and simultaneous analysis of multiple elements, NAA is suitable for the analysis of trace elements in biological samples . Experiment, if there are many elements of interest, often take full account of the radionuclides of each element to be tested, select the appropriate neutron flux and irradiation time, decay time, counting time. Under such circumstances, it is very important to choose the optimum experimental conditions correctly and reasonably. The traditional method is achieved through repeated experimental attempts and error methods, which can become very time-consuming
