本文应用FJ-332低本底β测量仪和FH一1906低本底NaI(T1)γ能谱仪,对中太平洋北部表层沉积物的总β放射性进行了定量分析和定性判别,并探讨了大洋沉积物总β放射性的分布与各种环境因子的相关关系,结合陆架浅海区沉积物放射性研究的有关资料,进一步证明海洋沉积物放射性调查研究必须与沉积环境、沉积物的理化特性等环境因子的调查研究相结合。
In this paper, FJ-332 low background β meter and FH 1906 low background NaI (T1) γ spectrometer were used to quantitatively analyze and qualitatively determine the total β radioactivity in the surface sediments of the northern part of the Central Pacific Ocean. Correlation between the distribution of total β radioactivity and various environmental factors in the sediments and the related data of the radioactive research on the sediments in shallow continental shelf areas further prove that the radioactive investigation of marine sediments must be related to the environmental factors such as sedimentary environment and physical and chemical properties of sediments Research combined.
