海洋沉积物中放射性的调查研究是海洋环境放射性调查研究的重要组成部分.海洋环境一般都不是被单一核素所沾污,为了快速监测海洋环境的放射性污染,以便尽快制定防护措施,通常采用总B放射性分析方法.海洋环境放射性监测一般是测定表层(0-5厘米)沉积物样品,很少涉及沉积物中放射性垂直分布的问题.沉积物中放射性垂直分布的探讨,不但对特定海区环境容量及自净能力的研究有重要意义,对放射性核素在海洋中迁移规律的研究以及对搞好海洋环境放射性质量评价工作亦有重要的参考价值.
The investigation of radioactivity in marine sediments is an important part of the radiological investigation of the marine environment, which is not generally contaminated by a single nuclide. In order to rapidly monitor the radioactive contamination of the marine environment in order to formulate protective measures as soon as possible, B. Radioactive analysis of the marine environment Radioactive monitoring of the marine environment is generally a measure of the sediment samples of the surface layer (0-5 cm) and rarely involves the vertical distribution of radioactivity in sediments. The vertical distribution of radioactivity in sediments not only affects the environmental capacity And self-purification ability of the research is of great significance, the study on the law of radionuclide migration in the ocean as well as to do a good job of radioactive quality assessment of the marine environment also has important reference value.
