Abstract

Prompt gamma ray activation analysis (PGAA) is a powerful non-destructive analytical method for bulk chemical composition. The prompt gamma ray spectra usually contain lots of peaks, and the measuring accuracy is often affected by the overlapping peaks and interference from neutron self-shielding effect, especially for filed application with a scintillator detector. Qualitative and quantitative analyses can only be performed by reliable spectra analytical approach. In this work, a new spectrum analysis method, which based on the elemental library spectra together with the neutron self-shielding correction model, is investigated for bulk sample determination. Based on the corrected measured spectra of complex samples after neutron self-shielding correction, the Standard Single Element Response Spectra (SSERS) are calculated for establishing the elemental library. For investigating the feasibility of the mentioned method, the method was applied for element detection of aqueous solutions containing chlorine (Cl), boron (B), cadmium (Cd) and mercury (Hg), with a designed PGAA detection system. The results indicate that the new spectra analytical method is efficient for bulk sample determination and accurate for the elemental analysis for aqueous solutions under the present experimental conditions.

PGAA技术测定大宗样品的标准单元素响应谱（SSERS）方法研究

提示伽马射线活化分析（PGAA）是一种功能强大的非破坏性分析方法。提示伽马能谱通常包含许多峰，测量精度经常受到峰重叠和中子自屏蔽效应的干扰，特别是在闪烁体探测器的现场应用中。定性和定量分析只能通过可靠的光谱分析方法进行。本文研究了一种基于元素库谱和中子自屏蔽校正模型的样品分析方法。根据中子自屏蔽校正后的复样品测量光谱，计算标准单元素响应谱，建立元素库。为考察该方法的可行性，设计了PGAA检测系统，将该方法应用于含氯（Cl）、硼(B)、镉（Cd）和汞（Hg）的水溶液中元素的检测。结果表明，在本实验条件下，新光谱分析方法对大量样品的测定是有效的，对水溶液的元素分析是准确的。

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
