摘要

核燃料循环依赖于矿石中铀含量的准确和可靠的量化。在这里，我们提供了一种伽马射线能谱法，采用高纯度锗（HPGe）探测器，在考虑伽马射线自衰减后，确定了德克萨斯州南部一个小矿石样品的总铀含量。我们展示了用238U系列的子产物234mPa产生的1001.0 keV伽马射线对铀含量的定量。利用152eu点源确定了不同伽马射线能量下矿样的衰减校正系数，显著提高了方法的精度。通过比较方法，我们展示了一种快速无损的方法，用于定量德克萨斯州矿石中的总铀含量为6.17±0.09 wt%，在26.5 g材料的2小时计数时间内相对不确定度为1.52%。

Rapid high precision analysis of uranium content in Texas ores using gamma-ray spectrometry

The nuclear fuel cycle relies on the accurate and reliable quantification of uranium content in ores. Here, we offer a gamma-ray spectrometry method employing high purity germanium (HPGe) detectors to determine the total uranium content of a small ore sample from south Texas after accounting for gamma-ray self-attenuation. We show the quantification of uranium content using the 1001.0 keV gamma-ray produced by the daughter product ^234mPa from the ²³⁸U series. We utilized a¹⁵²Eu point-source to determine an attenuation correction factor for the ore sample at varying gamma-ray energies to significantly improve the accuracy of the method. Through the comparator method, we show a quick non-destructive method for quantifying the total uranium content in a Texas ore of 6.17 ± 0.09 wt% with a 1.52 % relative uncertainty within a 2 h count time utilizing 26.5 g of material.

期刊介绍： The Journal of Environmental Radioactivity provides a coherent international forum for publication of original research or review papers on any aspect of the occurrence of radioactivity in natural systems. Relevant subject areas range from applications of environmental radionuclides as mechanistic or timescale tracers of natural processes to assessments of the radioecological or radiological effects of ambient radioactivity. Papers deal with naturally occurring nuclides or with those created and released by man through nuclear weapons manufacture and testing, energy production, fuel-cycle technology, etc. Reports on radioactivity in the oceans, sediments, rivers, lakes, groundwaters, soils, atmosphere and all divisions of the biosphere are welcomed, but these should not simply be of a monitoring nature unless the data are particularly innovative.
