Uranium, protactinium and thorium radionuclide activities in surface sediments of the continental slope of the Argentine basin

This is a set of bulk sediment analyses of 230Th, 232Th, 231Pa as well as uranium isotopes in surface sediments from the continental slope of the Argentine basin. Samples were subject to full digestion, and radioisotope data were determined using isotope dilution after ion chromatographic separation, electroplating and counting via alphaspectrometry (233Pa yield tracer: beta-counting) by Steffen Niemann as part of his diploma thesis in 2003 (supervision FU Berlin- Prof. Heubeck/ AWI Bremerhaven-Dr. Walter Geibert and Prof. Michael Schlüter).

本数据集收录了阿根廷海盆大陆坡表层沉积物中230Th、232Th、231Pa以及铀同位素的批量沉积物分析结果。样品经过彻底消化处理，并通过离子色谱分离、电镀及α能谱测量（233Pa产率示踪剂：β计数）等方法确定放射性同位素数据，上述工作由Steffen Niemann于2003年作为其毕业论文的一部分完成（指导教师：柏林自由大学Heubeck教授/不莱梅哈芬AWI研究所Walter Geibert博士和Michael Schlüter教授）。
