摘要
瞬发γ中子活化分析是重要的核分析方法之一, 是H和B等轻元素的重要分析手段,近年来应用范围不断增加. 概要介绍了瞬发γ中子活化分析的基本原理, 重点介绍了中国原子能科学研究院重水研究堆热中子束瞬发γ中子活化分析实验装置以及 50keV—11MeV的宽能区γ效率刻度方法. 还应用瞬发γ中子活化分析方法分析了海底锰结核标准物质GSPN 3中 11种元素, 结果与标准值基本一致.
Neutron-induced prompt-γ activation analysis(PGNAA) is one of the nuclear analytical methods,which is a powerful tool for.quantitive determination of H,B,etc.The applications of PGNAA are increased in recent years.In this paper,the basic principle of PGNAA was introduced briefly.The facilities of PGNAA in HWRR of China Institute of Atomic Energy as well as the efficiency calibration for a wide range gamma from 50 keV to 10 MeV were emphasized.A deep sea polymetallic nodule CRM,GSPN-3 was analyzed by using PGNAA,and the results are in agreement with the certified values.
