Ebagoola uranium 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 uranium grid has a cell size of 0.00083 degrees (approximately 91m) and shows uranium element concentration of the Ebagoola, QLD, 1990 in units of parts per million (or ppm). 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.

放射测量法（radiometric method），亦称伽马射线能谱法（gamma-ray spectrometric method），通过探测地球表面附近的伽马射线自然变化，反映钾（K）、铀（U）与钍（Th）天然放射性衰变所产生的辐射波动。所采集的数据将通过标准化流程进行处理，以确保记录到的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用于解译，以揭示地下地质构造。处理后的数据将由GA地球物理学家开展质量核验，确保GA发布的最终数据符合使用要求。
本放射测量铀格网（radiometric uranium grid）的单元尺寸为0.00083度（约合91米），展示了1990年昆士兰州（QLD）埃巴古拉（Ebagoola）地区的铀元素浓度数据，单位为百万分之一（ppm）。用于生成该格网的数据由昆士兰州政府（QLD Government）于1990年采集，总测线长度达44711测线公里，测线间距为400米，航空测量离地高度为100米。
