摘要

放射性物质可能包含原始放射性核素，以及存在于海洋环境中的人为、核事故和废物处理产生的放射性核素。本综述探讨了有效采样和检测海洋放射性核素的各种方法。本文讨论了可采集的不同类型样本，包括水、沉积物、生物群和悬浮颗粒物。此外，本文还讨论了用于放射性核素检测的各种分析技术，如伽马光谱法和放射化学分离法。综述强调了根据特定放射性核素、环境条件和所需灵敏度水平选择适当采样和检测方法的重要性。它还强调了在复杂的海洋环境中取样和检测放射性核素所面临的挑战。这些挑战包括放射性核素浓度低、天然基质的干扰和污染风险。

Overview of marine radionuclides from sampling to monitoring

Radioactive materials may contain primordial radionuclides, and radionuclides of anthropogenic, nuclear accident, and waste disposal which are present in marine environments. This review explores various approaches for the effective sampling and detection of marine radionuclides. The different types of samples that can be collected, including water, sediment, biota, and suspended particulate matter are discussed. Additionally, this paper discusses the various analytical techniques employed for radionuclide detection, such as gamma spectrometry and radiochemical separation. The review emphasizes the importance of choosing appropriate sampling and detection methods based on the specific radionuclides, environmental conditions, and the desired level of sensitivity. It also highlights the challenges associated with their sampling and detection in complex marine environments. These include low radionuclide concentrations, interference from natural matrices, and contamination risks.

期刊介绍： Pure and Applied Chemistry is the official monthly Journal of IUPAC, with responsibility for publishing works arising from those international scientific events and projects that are sponsored and undertaken by the Union. The policy is to publish highly topical and credible works at the forefront of all aspects of pure and applied chemistry, and the attendant goal is to promote widespread acceptance of the Journal as an authoritative and indispensable holding in academic and institutional libraries.
