Glengarry Peak Hill Robinson Range Areas ABC,1994 (P631), 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 Glengarry Peak Hill Robinson Range Areas ABC,1994 (P631), radiometric line data, AWAGS levelled were acquired in 1994 by the WA Government, and consisted of 118765 line-kilometres of data at 400m line spacing and 60m 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，通过探测地表附近的伽马射线自然变化，量化反映钾（K）、铀（U）与钍（Th）的天然放射性衰变产生的信号。
所采集的数据将通过标准流程处理，以确保记录到的响应信号仅源自地下岩层。
处理后得到的数据集可通过解译揭示地下地质构造。
经处理的数据将由澳大利亚地质调查局（Geoscience Australia，GA）的地球物理学家开展质量核查，以确保该局发布的最终数据符合使用要求。
本次数据集为1994年由西澳大利亚州政府（Western Australia Government，WA）采集的格伦加里峰希尔-鲁滨逊岭区域ABC（1994年，编号P631）放射性测量航线数据，已完成全澳航空地球物理调查（Australia-wide Airborne Geophysical Survey，AWAGS）水准校正，总航线长度达118765线公里，航线间距为400米，飞行离地高度为60米。
为约束数据中的长波长信号，研究团队采用独立数据集——全澳航空地球物理调查（AWAGS）航空磁测数据——对本次调查数据的基准水平进行校正控制。
本次调查数据已基本完成AWAGS基准水准校正。
