The Purdue Rare Isotope Measurement Laboratory (PRIME Lab) routinely measures 10Be, 26Al, 36Cl and 129I in rock, soil, water, and air for a large community of NSF-sponsored and other users providing i) state-of-the-art measurements for routinely-utilized radionuclides for the NSF user community, ii) chemical preparation services for those NSF investigators who do not have their own in-house laboratories or expertise, iii) new measurement techniques that will be used in future geoscience investigations, and iv) NSF geoscience investigators with the knowledge needed to apply radionuclides to geoscience problems. The measurement of radionuclides by accelerator mass spectrometry (AMS) is an essential component of the study of Earth surface processes and Quaternary geology. These radionuclides are used to date landforms, fluids, and sediments, and to determine rates of erosion, soil formation, and tectonic deformation, geologic processes that directly impact human populations. These measurements are reported in hundreds of scientific reports published in numerous internationally recognized journals. We are actively engaged in teaching sample preparation methods to the next generation of researchers, independent of their affiliation. PRIME Lab also employs numerous undergraduate Purdue University students, teaching them the basics of data acquisition and data analysis. PRIME Lab plays a significant role in the larger education community in the West Lafayette area. Working together with the College of Science counselor and the Department of Physics Outreach Director, PRIME Lab hosts hundreds of students annually on laboratory tours.

普渡（Purdue）稀有同位素测量实验室（Prime Lab）通常在岩石，土壤，水，水和空气中进行10BE，26AL，36Cl和129i，用于大型NSF赞助的大型社区和其他用户，为i）提供最先进的测量值，以适用于NSF用户的常规核能核能的最先进的NSF用户，以供NSF用户提供NSF的调查员，II）在II中，II）ii nsf thing ins-ii thing ins ins-ii）ii nsf thing ins-ii to in II）ii nsf专业知识，iii）将在未来的地球科学研究中使用的新测量技术，以及IV）NSF地球科学研究者，具有将放射性核素应用于地球科学问题所需的知识。通过加速器质谱法（AMS）测量放射性核素是地球表面过程和第四纪地质研究的重要组成部分。这些放射性核素用于日期，以确定地形，流体和沉积物，并确定侵蚀，土壤形成和构造变形的速率，直接影响人类种群的地质过程。这些测量值在许多国际认可期刊上发表的数百份科学报告中进行了报道。我们积极参与向下一代研究人员进行样本准备方法，而与他们的隶属关系无关。 Prime Lab还雇用了众多普渡大学的本科生，教给他们数据获取和数据分析的基础知识。 Prime Lab在西拉斐特地区的大型教育社区中起着重要作用。 Prime Lab与理学顾问学院和物理外展总监一起工作，每年在实验室旅行中接待数百名学生。
