Cue Kirkalocka Ninghan Yalgoo potassium 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 Cue-Kirkalocka-Ninghan-Yalgoo-Badja-Kylie Hills merge, 1995-2004 in units of percent (or %). The data used to produce this grid was acquired in 1995 by the WA Government, and consisted of 124601 line-kilometres of data at a line spacing between 200m and 400m, and 60m terrain clearance.

放射性测量法（radiometric, or gamma-ray spectrometric method）通过检测地表附近的伽马射线自然变化量，来反映钾（K）、铀（U）和钍（Th）的自然放射性衰变所产生的辐射信号。所采集的数据将通过标准化流程开展处理，以确保记录的辐射响应仅源于地下岩石的放射性衰变。经处理得到的数据集可通过解译，揭示地下地质构造特征。经处理的数据将由GA地球物理学家开展质量校验，以确保GA发布的最终数据符合使用需求。本次发布的放射性钾元素格网数据像元大小为0.00083度（约87米），展示了1995年至2004年期间Cue-Kirkalocka-Ninghan-Yalgoo-Badja-Kylie Hills合并测区的钾元素浓度分布，单位为百分比（%）。用于生成该格网的数据由西澳州政府（WA）于1995年采集，总测线长度达124601线公里，测线间距介于200米至400米之间，飞行离地高度为60米。
