Advances in x-ray spectrometry: new science through new sources

这一建议旨在推动x射线光谱，新的科学产生新的辐射源。该研究涉及开发和使用x射线荧光和x射线吸收技术来检测微量元素，如铅、砷和硒。该提案关注的是这些方法带来的科学挑战和机遇。即使接触中等水平的铅和砷也可能产生严重的影响。利用基于实验室和同步加速器的新来源，该提议旨在显著提高我们对这些元素的分布和命运的理解。目标包括在以下相互关联的研究主题中使用x射线光谱法：(1)开发一种创新和紧凑的单能x射线方法用于微量元素检测；(2)全便携式微型x射线管技术的优化与验证；(3)利用加拿大光源同步辐射研究组织样品中的元素分布和化学形态。

This proposal seeks to advance x-ray spectrometry, with new science resulting from new radiation sources. The research involves the development and use of x-ray fluorescence and x-ray absorption techniques for the detection of trace elements such as lead, arsenic, and selenium. The proposal is concerned with the scientific challenges and opportunities posed by these methods. Effects from exposure to even moderate levels of lead and arsenic may be severe. Using novel lab-based and synchrotron-based sources, this proposal aims to significantly improve our understanding of the distribution and fate of such elements. Objectives include the use of x-ray spectrometry in the following interrelated themes of research: (1) development of an innovative and compact mono-energetic x-ray approach for trace element detection; (2) optimization and validation of fully portable miniature x-ray tube techniques; and (3) investigations through synchrotron radiation at the Canadian Light Source to probe elemental distribution and chemical form in tissue samples.
