来自拉蒙特-多尔蒂地球观测站、罗德岛大学和明尼苏达大学双城分校的研究人员计划开展一项相互校准工作,作为GEOTRACES项目的一部分,重点关注放射性核素(230、231Pa、10Be、239+240Pu、237Np、137Cs、240Pu/239Pu)、稀土元素和钕同位素。此互校准的目的是确保不同国家和国际实验室使用的各种取样、分析和储存方法获得准确、精确和内部一致的结果。就更广泛的影响而言,拟议活动的结果将为科学界提供必要的协议,以便准确和精确地测量放射性核素、稀土元素和钕同位素,无论哪个实验室产生数据,都可以进行比较/对比。
英文摘要
Investigators from Lamont-Doherty Earth Observatory, the University of Rhode Island, and the University of Minnesota-Twin Cities plan to carry out an intercalibration exercise as part of the GEOTRACES Program focusing on radionuclides (230Th, 231Pa, 10Be, 239+240Pu, 237Np, 137Cs, 240Pu/239Pu), rare earth elements, and neodymium isotopes. The goal of this intercalibration is to ensure the various sampling, analyses, and storage methods used by different national and international laboratories obtain results that are accurate, precise, and internally consistent.In terms of broader impacts, the outcome of the proposed activities would provide the science community with the necessary protocols to accurately and precisely measure radionuclide, rare earth elements, and neodymium isotopes that can be compared/contrasted regardless of which laboratory generated the data.
