摘要 近年来,天然放射性核素镭-226对人类健康的影响越来越受到重视,国内外围绕镭-226的检测方法开展了一系列研究。目前常用的镭-226检测方法有射气闪烁法、γ能谱法、液体闪烁计数法、α能谱法和α计数法。射气闪烁法是镭-226的经典检测方法,发展较为成熟,γ能谱法和液体闪烁计数法的研究进展较快。由于镭-226的辐射特性,这些检测方法依然存在样本需求量大、检测周期长、步骤烦琐、探测限高和回收率低等问题。本文对镭-226常用的5种检测方法研究进行综述,并评述其优缺点,为不同类型样品检测方法的选择和优化、我国标准方法的完善提供参考。

Abstract:Recent years have witnessed more attention paid to the health effects of the natural radionuclide 226Ra, and a series of research carried out on the detection methods of 226Ra at home and abroad. The common 226Ra detection methods are emanation scintillation, gamma spectrometry, liquid scintillation counting, alpha spectrometry and alpha counting. Emanation scintillation is mature enough as a classical method, while gamma spectrometry and liquid scintillation counting proceed fast. Due to the radiation of 226Ra, these detection methods still have the problems such as the requirement for large samples, long detection periods, complicated steps, high detection limits and low recovery rates. This paper reviews the five methods above and summarize their advantages and disadvantages, so as to provide the reference for selecting and optimizing the detection methods for different samples as well as perfecting the standard method in China.
