摘要

摘要:本研究旨在确定几内亚湾沿岸喀麦隆杜阿拉盆地及周边地区7个大型采石场的天然放射性核素浓度、化学成分和地质来源。使用伽玛和x射线能谱技术对总共24个样本进行了分析。伽马能谱分析结果表明，来自研究地区的样品所含的天然放射性量低于全球商定的安全限度。x射线荧光光谱法测定了主要元素、次要元素和微量元素的定量浓度，用于构造辨析图，表明这些沉积物沉积于被动边缘环境。这些浓度和天然放射性核素放射性水平数据为喀麦隆这一区域以及更广泛的几内亚湾提供了一个参考数据库。图形抽象

Determination of the natural radioactivity, elemental composition and geological provenance of sands from Douala in the littoral region of Cameroon using X-ray and γ-ray spectrometry

ABSTRACT This study aimed to determine the concentration of natural radionuclides, the chemical composition, and the geological provenance of sand samples from seven large quarries within the Douala Basin and surrounding locations within the Littoral Region of Cameroon along the Gulf of Guinea. The analyses were undertaken on a total of 24 samples, using both gamma- and X-ray spectrometry techniques. Gamma spectrometric results indicated that the samples from the study area contained amounts of natural radioactivity that are less than the globally agreed safe limits. X-ray fluorescence spectrometry yielded quantitative major, minor, and trace element concentrations that were used in tectonic discrimination diagrams, indicating that these sediments were deposited in a passive margin environment. These concentration and natural radionuclide radioactivity level data provide a reference database for this region of Cameroon as well as for the wider Gulf of Guinea. GRAPHICAL ABSTRACT
