GSQ Cooper Basin West pctk 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 potassium grid has a cell size of 0.00083 degrees (approximately 87m) and shows potassium element concentration of the Cooper Basin West, Qld, 2007-08 in units of percent (or %). The data used to produce this grid was acquired in 2007 by the QLD Government, and consisted of 209621 line-kilometres of data at 400m line spacing and 60m terrain clearance.

放射性测量法（又称伽马能谱法）通过检测地球表面附近的伽马射线自然变化，来测量钾（K）、铀（U）和钍（Th）的自然放射性衰变所产生的信号。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释揭示地下地质结构。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。
该放射性钾网格的单元格大小为0.00083度（约87米），显示了2007-08年昆士兰州（Qld）西部库珀盆地的钾元素浓度，单位为百分比（%）。生成该网格所用的数据由昆士兰州政府（QLD Government）于2007年采集，包含209621线公里的数据，线间距为400米，地形净空高度为60米。
