The 4th International Ra-Rn Workshop June 3-8, 2012

该奖项的资金将提供部分资金给罗得岛大学第四届国际镭和氡讲习班，最近的一个正在进行的国际讲习班系列致力于发展和新的方向，在应用和测量镭（Ra）同位素和氡（Rn）作为示踪剂在环境中。 镭和氡同位素的精确测量和建模非常重要，因为它们已成为确定海底地下水排放（SGD）到海洋的通量、沿海沃茨的混合速率、水在河口的停留时间以及地表水和地下水之间的相互作用的越来越重要的工具。研讨会将为越来越多的科学家提供一个重要论坛，讨论与测量镭-223、镭-224、镭-226、镭-228、氡-220和氡-222相关的益处和挑战，以及用于将结果应用于环境问题的模型。 此前在摩纳哥、威尼斯和耶路撒冷（如下所列）举行的Ra-Rn研讨会已经确定了一些与水生系统中Ra和Rn的应用和准确测量相关的问题。这些问题和其他问题将大大受益于与更广泛的科学界的讨论，正如为这次研讨会所建议的那样。更广泛的影响：讲习班将提供一个及时和宝贵的机会，继续就Ra和Rn示踪剂的应用开展讨论，提供科学和方案最新情况，并促进国际合作。在提交提案时，来自15个国家的54名与会者登记参加了讲习班。传播会议成果的拟议机制包括在地球观测系统、澳大利亚地质学家联合会/澳大利亚地质学家组织特别会议上发表一篇简短的摘要文章，以及在一份学院商定的顶级科学期刊上发表一期同行评审出版物特刊。以这些方式传播会议成果将使更广泛的科学界，包括学生和初出茅庐的科学家了解最新的发展情况。

Funds from this award to the University of Rhode Island will provide partial funding for the Fourth International Radium and Radon Workshop, the latest in an ongoing international workshop series devoted to developments and new directions in the application and measurement of radium (Ra) isotopes and radon (Rn) as tracers in the environment. The accurate measurement and modeling of radium and radon isotopes is important because they have become increasingly important tools for determining fluxes of submarine groundwater discharge (SGD) into the ocean, rates of mixing of coastal waters, residence times of water in estuaries, and interactions between surface water and groundwater. The workshop will provide an important forum for a growing community of scientists to discuss the benefits and challenges associated with the measurement of radium-223 , radium-224, radium-226, radium-228, radon-220, and radon-222 , as well as models used to apply the results to environmental problems. Prior Ra-Rn workshops held in Monaco, Venice, and Jerusalem (listed below) have identified a number of issues related to the application and accurate measurement of Ra and Rn in aquatic systems. These and other issues would greatly benefit from discussions with the broader scientific community, as proposed for this workshop. Broader Impacts: The workshop would provide a timely and valuable opportunity to continue to develop discussions on the application of Ra and Rn tracers, provide scientific and programmatic updates, and foster international collaboration. At the time of the proposal submission, 54 participants from 15 countries had registered for the workshop. Proposed mechanisms to disseminate the meeting results include a short synopsis article in EOS, AGU/ASLO special session(s), and a special issue of peer-review publications to be published in a collegially agreed-upon top scientific journal. Dissemination of the meeting results in these ways would inform the broader scientific community, including students and early career scientists, of the latest developments.
