Dixon Range Gordon Downs uranium grid geodetic

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.This radiometric uranium grid has a cell size of 0.00083 degrees (approximately 80m) and shows uranium element concentration of the Dixon Range - Gordon Downs, WA, 1991 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1992 by the WA Government, and consisted of 43000 line-kilometres of data at 400m line spacing and 100m terrain clearance.

辐射测量法（又称伽马射线光谱法）用于测量地球表面附近探测到的伽马射线的自然变化，这些变化源于钾（K）、铀（U）和钍（Th）的天然放射性衰变。采集的数据通过标准方法处理，以确保记录的响应仅来源于地下岩石。处理结果生成的数据集可通过解译揭示地下地质结构。处理后的数据由GA地球物理学家进行质量检查，以确保GA发布的最终数据符合预期用途。
该辐射测量铀网格的单元格大小为0.00083度（约80米），显示了1991年西澳大利亚（WA）迪克森山脉-戈登唐斯地区的铀元素浓度，单位为百万分之一（ppm）。生成该网格所用的数据由西澳大利亚政府于1992年采集，包含43000测线公里的数据，测线间距为400米，地形净空高度为100米。
