Abstract

The detection of nuclear materials is crucial in cases of potential leaks or accidents; however, transporting samples out of such locations may be challenging, necessitating on-site analysis. While total reflection X-ray fluorescence (TXRF) analysis is a highly useful method for determining nuclides with long half-lives, such as uranium isotopes, no commercially available portable TXRF spectrometers can currently operate without an external power source, which may not always be accessible on-site. In this study, we modified the design of a commercially available portable TXRF spectrometer to develop a battery-powered device, enabling TXRF analysis outdoors and in locations without an external power supply. To test the applicability of the device, we analyzed the uranium content in a sample solution, using yttrium as an internal standard. The relative sensitivity coefficient was the same as that of the commercial spectrometer but the limit of detection was deteriorated. Addressing the equipment issues identified in this study is expected to enable efficient and rapid on-site TXRF analysis.

便携式电池供电全反射x射线荧光光谱仪的研制。

在可能发生泄漏或事故的情况下，探测核材料至关重要；然而，将样品运出这些地点可能具有挑战性，需要现场分析。虽然全反射x射线荧光（TXRF）分析对于确定半衰期长的核素（如铀同位素）是一种非常有用的方法，但目前没有市售的便携式TXRF光谱仪可以在没有外部电源的情况下工作，这些电源可能并不总是可以在现场使用。在这项研究中，我们修改了市售便携式TXRF光谱仪的设计，开发了一种电池供电的设备，可以在室外和没有外部电源的地方进行TXRF分析。为了测试该装置的适用性，我们分析了样品溶液中的铀含量，使用钇作为内标。相对灵敏度系数与商用光谱仪相同，但检出限变差。解决本研究中确定的设备问题有望实现高效、快速的现场TXRF分析。
