GSWA Mt Anderson McLarty Hills North Canning 3 ppm 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 0.00081 degrees (approximately 88m) and shows uranium element concentration of the Mt Anderson - McClarty Hills, WA, 2009 (North Canning 3) in units of parts per million (or ppm). The data used to produce this grid was acquired in 2009 by the WA Government, and consisted of 99192 line-kilometres of data at 400m line spacing and 60m terrain clearance.

放射性测量法（或称伽马射线能谱法）通过检测地球表面附近的伽马射线自然波动，对钾（K）、铀（U）与钍（Th）的天然放射性衰变所产生的辐射信号进行量化。所采集的数据将通过标准化处理流程进行优化，以确保记录到的响应仅源自地下岩石的辐射。经处理得到的数据集可通过地质解译，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核查，以确保GA发布的最终数据满足使用需求。
本放射性铀元素栅格数据的像元大小为0.00081度（约88米），展示了2009年西澳大利亚州（WA）安德森山-麦克拉蒂山地区（北坎宁3区）的铀元素浓度，单位为百万分率（ppm）。本栅格数据所用的原始数据集由西澳大利亚州政府于2009年采集，总测线长度达99192线公里，测线间距为400米，飞行地形离地高度为60米。
