本文介绍国外近年来堆中子短照活化分析和缓发中予测铀的进展。由于某些元素活化后只有短半衰期的γ射线适合测量,有些元素用短半衰期核素进行分析其结果的精度不低于用中长半衰期核素进行分析所得的结果。而另一些核素的分析结果虽然精确度差一些,但是由于它能够迅速给出分析结果,成本低以及可自动分析大量的样品等优点而得到补偿,因此堆中 In this paper, the recent advances in the analysis of heap neutron activation and uranium depletion in foreign countries are introduced. Since some elements are only suitable for the measurement of γ-rays with short half-lives after their activation, some elements are analyzed with short half-life nuclides whose accuracy is not lower than that obtained with the analysis of medium- and long-half-life nuclides. Other nuclides, though less accurate, are compensated for the rapid availability of analytical results, low cost, and the ability to automatically analyze a large number of samples. Therefore,
