SA Exploration Initiative - Area A6, SA., 1993 (P700), radiometric line data, AWAGS levelled

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 SA Exploration Initiative - Area A6, SA., 1993 (P700), radiometric line data, AWAGS levelled were acquired in 1992 by the SA Government, and consisted of 330915 line-kilometres of data at 400m line spacing and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

放射性测量法（又称伽马能谱法）通过探测地球表面附近的伽马射线自然变化，来反映由钾（K）、铀（U）与钍（Th）的天然放射性衰变所产生的伽马射线信号特征。所采集的数据将通过标准化流程进行处理，以确保记录的测量响应仅源自地下岩石的放射性活动。经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地球物理学家开展质量检查，以确保GA发布的最终数据符合使用需求。
本次数据集为1993年（编号P700）的SA勘探计划A6区域伽马能谱测线数据，经澳大利亚全国航空地球物理调查（Australia-wide Airborne Geophysical Survey, AWAGS）平差校正。该数据由SA政府于1992年采集，总测线长度达330915测线公里，测线间距为400米，飞行离地高度为80米。
为约束数据中的长波长分量，研究人员采用独立数据集——澳大利亚全国航空地球物理调查（AWAGS）航空磁测数据，对本次勘探数据的基准水平进行校正。
本次勘探数据本质上已按AWAGS标准完成平差校正。
