GSQ Cloncurry 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 0.00018 degrees (approximately 19m) and shows potassium element concentration of the Isa Region Airborne Magnetic Radiometric and DEM Survey, QLD, 2017 in units of percent (or %). The data used to produce this grid was acquired in 2017 by the QLD Government, and consisted of 113387 line-kilometres of data at a line spacing between 50m and 100m, and 50m 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的伽马射线自然变化，反映钾（K）、铀（U）和钍（Th）的自然放射性衰变过程。采集的数据经标准方法处理，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用于解析地下地质结构。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。
该辐射测量钾元素网格的像元大小为0.00018度（约19米），展示了2017年昆士兰州（QLD）伊萨地区航空磁测辐射测量与数字高程模型（DEM）调查中的钾元素浓度，单位为百分比（%）。生成该网格所用的数据由昆士兰州政府于2017年采集，包含113387线公里的数据，线间距为50至100米，地形净空高度为50米。
