5028 Block 2 (Southeast) Grid of uranium ground concentration with NASVD and standard reductions applied

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 degrees (approximately m) and shows uranium element concentration of the Narryer in units of parts per million (or ppm). The data used to produce this grid was acquired in 2024 by the WA Government, and consisted of 415090 line-kilometres of data at 100m line spacing and 50m terrain clearance.放射性测量法（radiometric method，又称伽马能谱法（gamma-ray spectrometric method））通过检测地球表面附近探测到的伽马射线自然变化，来反映由钾（K）、铀（U）与钍（Th）的天然放射性衰变所引发的辐射信号。采集所得数据将通过标准化流程开展处理，以确保记录的响应信号仅由地下岩石产生。处理得到的数据集可通过地质解译，用以揭示地下地质构造。经处理的数据将由GA地球物理学家进行质量核查，以确保GA发布的最终数据满足使用要求。该放射性铀网格的单元格尺寸为 度（约 米），展示了纳里耶地区的铀元素浓度，单位为百万分率（ppm）。用于生成该网格的数据由西澳大利亚州（WA）政府于2024年采集，总测线里程达415090线公里，测线间距为100米，地形离地高度为50米。
