Nabberu combined ppm uranium 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 88m) and shows uranium element concentration of the Nabberu North-South merge, 1996 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1996 by the WA Government, and consisted of 44375 line-kilometres of data at 400m line spacing and 80m terrain clearance.

辐射测量法（或称伽马射线光谱法）通过检测地球表面附近伽马射线的天然变化，测量钾（K）、铀（U）和钍（Th）天然放射性衰变产生的信号。采集的数据经标准方法处理，确保记录的响应仅源于地下岩石。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，以保证GA发布的最终数据符合用途要求。

该辐射测量铀网格的单元格大小为0.00083度（约88米），显示1996年Nabberu南北合并区域的铀元素浓度，单位为百万分之一（ppm）。生成此网格的数据由西澳大利亚州政府（WA Government）于1996年采集，包含44375测线公里数据，线间距400米，离地高度80米。
