An International Collaboration to Study Soil Profiles of Chernobyl Fallout Radionuclides

0745066马蒂索夫2007年秋季的这次国际计划访问将使三名美国高级研究人员和一名初级研究人员能够前往瑞典和波兰进行实地工作，进行初步采样和数据分析，以确定切尔诺贝利衍生的放射性核素在土壤中的去向和迁移。美国首席调查员是凯斯西医学院的杰拉尔德·马蒂索夫，联合调查员是北亚利桑那大学的迈克尔·凯特勒和凯斯西医学院的彼得·怀廷。他们的国际合作者是克拉科夫Henryk NiewodNiczaski核物理研究所的Jerzy Mietelski，以及乌普萨拉瑞典农业科学大学的Klas Rosen和Ingrid Oborne。这次计划访问的目的是利用美国和国际合作伙伴的专业知识，并通过访问采样点和现有数据集，扩大对控制土壤中放射性核素的基本过程的了解和量化。从这项工作中收集的初步数据将用于制定后续的研究建议，供国家科学基金会审议。了解控制土壤中放射性核素的因素可能有助于更好地估计土壤过程和泥沙运移的速率和机制，这对基础和应用地球科学具有相当大的价值。如果成功，这项工作可能有助于我们了解输送到土壤表面的化学品对健康的影响，并导致更好地对污染物释放做出反应的知情程序。这种国际合作还通过让美国本科生、研究生和博士后研究人员参与新样本的实验室分析，以及准备样本和数据以供发布并在课程和高级顶峰项目中更广泛地使用，进一步提高了教育和培训的能力。

0745066MatisoffThis international planning visit during fall 2007 will enable three US senior researchers and one junior researcher to travel to Sweden and Poland for field work to carry out preliminary sampling and data analysis to determine the fate and transport of Chernobyl-derived radionuclides in soils. The US principal investigator is Gerald Matisoff of Case Western School of Medicine and the co-PIs are Michael Ketterer of Northern Arizona University and Peter Whiting of Case Western School of Medicine. Their international collaborators are Jerzy Mietelski of The Henryk Niewodniczaski Institute of Nuclear Physics in Krakow, and Klas Rosen and Ingrid Oborn of the Swedish University of Agricultural Sciences in Uppsala. The purpose of the planning visit is to leverage the expertise of the US and international partners and, through access to sampling sites and existing data sets, expand the understanding and quantification of fundamental processes controlling radionuclides in soils. The preliminary data collected from this effort will be used in the formulation of a subsequent research proposal for NSF consideration. Understanding the factors controlling radionuclides in soils will likely enable better estimates of rates and mechanisms of soil processes and of sediment transport, which have considerable value to basic and applied earth science. If successful, this work may help us understand the health implications of chemicals delivered to the soil surface and lead to better informed procedures for responding to the release of contaminants. This international cooperation furthermore builds capacity in education and training by including U.S. undergraduate, graduate and post-doctoral researchers in laboratory analysis of new samples and the preparation of samples and data for release and wider use in courses and senior capstone projects.
