Ebagoola 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 91m) and shows potassium element concentration of the Ebagoola, QLD, 1990 in units of percent (or %). The data used to produce this grid was acquired in 1990 by the QLD Government, and consisted of 44711 line-kilometres of data at 400m line spacing and 100m terrain clearance.

辐射测量法（radiometric method，亦称伽马射线能谱法）可检测地球表面附近的伽马射线自然变化，该变化源自钾（K）、铀（U）和钍（Th）的天然放射性衰变。所采集的数据将通过标准流程进行处理，以确保记录的响应仅源自地下岩石。处理后得到的数据集可通过解译揭示地下地质构造。经处理的数据将由GA地球物理学家进行质量核验，以确保GA发布的最终数据符合使用要求。该辐射测量钾元素网格的单元尺寸为0.00083度（约91米），展示了1990年昆士兰州（QLD）伊巴古拉（Ebagoola）地区的钾元素浓度，单位为百分比（%）。用于生成该网格的数据由昆士兰州政府于1990年采集，总测线长度达44711线公里，测线间距为400米，地形离地高度为100米。
