航空放射性测量是美国能源部国家铀资源评价计划(NURE)中的一部分。在这过程中,外露片(异常)的识别是圈定放射性元素比预期偏高或偏低区域的一种重要手段。本文介绍的这种区域圈定方法可归结为三个步骤:根据测区有利性的不同选择偏高(或偏低)阈值;应用样本百分数以识别所有有意义的测点;在所选择的数据范围内进行窗滑动以确定异常点的非偶然群。应用这三个步骤处理了在怀俄明州Copper山地区采集的~(214)Bi(当量铀)航空放射性测量数据,从而识别出程度不同的富集区域。
Aeronautical radioactivity measurements are part of the U.S. Department of Energy’s National Uranium Resource Assessment Program (NURE). In this process, the identification of extrinsic patches (anomalies) is an important means of delineating areas of higher or lower radioactivity than expected. This method of area delineation presented in this article can be summarized in three steps: a high (or low) threshold is chosen based on the suitability of the field; the sample percentage is used to identify all meaningful points; within the selected data range A non-accidental group within which a window slips to identify outliers. Using these three steps, aerosol radioactive measurements of ~ (214) Bi (Uranium) collected in the Copper Mountain area of Wyoming were processed to identify areas of varying abundance.
