Buchanan, NT, 2002 - company5 2 (P1023), radiometric line data

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 Buchanan, NT, 2002 - company5 2 (P1023), radiometric line data were acquired in 2002 by the NT Government, and consisted of 175073 line-kilometres of data at 400m line spacing and 80m terrain clearance.

放射性测量法（radiometric method），亦称伽马射线能谱法，用于检测地表附近的伽马射线自然变化，该变化源于钾（K）、铀（U）与钍（Th）的天然放射性衰变。所采集的数据将通过标准化流程进行处理，以确保记录的响应信号仅来源于地下岩石的辐射。经处理得到的数据集可通过解译，揭示地下地质构造特征。经处理后的数据将由GA地球物理学家开展质量校验，确保GA发布的最终数据符合使用需求。编号为company5 2 (P1023)的2002年北领地（NT）布坎南区域测线放射性数据由北领地政府于2002年采集，总测线长度达175073线公里，测线间距为400米，地形离地高度为80米。
