GSWA South Canning 1 Madley Herbert 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 88m) and shows potassium element concentration of the Madley-Herbert, WA, 2010 (South Canning 1) in units of percent (or %). The data used to produce this grid was acquired in 2010 by the WA Government, and consisted of 96079 line-kilometres of data at 400m line spacing and 60m terrain clearance.

放射性测量法，又称伽马能谱法（gamma-ray spectrometric method），通过检测地球表面附近的伽马射线自然变化，量化由钾（K）、铀（U）和钍（Th）自然放射性衰变产生的辐射响应。所采集的原始数据将通过标准流程进行预处理，以确保记录的辐射响应仅源自地下岩石。经处理后得到的数据集可通过解译揭示地下地质构造特征。预处理后的数据将由GA地球物理学家开展质量核验，以确保GA发布的最终数据符合应用需求。本放射性钾元素栅格数据的单元格尺寸为0.00083度（约88米），展示了2010年西澳大利亚州（WA）Madley-Herbert地区（南卡宁1区）的钾元素浓度，单位为百分比（%）。本栅格数据的原始采集工作由西澳大利亚州政府（WA Government）于2010年完成，原始数据总测线长度达96079线公里，测线间距为400米，地形离地高度为60米。
