Robinson Range Belele 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 0.00083 degrees (approximately 88m) and shows uranium element concentration of the Robinson Range - Belele, WA, 2003 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2003 by the WA Government, and consisted of 53021 line-kilometres of data at 400m line spacing and 60m terrain clearance.

放射性测量法（亦称伽马射线能谱法）通过检测地球表面附近的伽马射线自然波动，以表征钾（K）、铀（U）及钍（Th）的自然放射性衰变所产生的辐射信号。所采集的数据将通过标准化流程处理，确保记录的辐射响应仅源于地下岩石的辐射贡献。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使用需求。本次放射性铀元素网格的像元尺寸为0.00083度（约88米），展示了2003年西澳大利亚州（Western Australia，WA）罗宾逊岭-贝莱勒区域的铀元素浓度，单位为百万分率（parts per million，简称ppm）。用于生成该网格的数据由西澳大利亚州政府于2003年采集，总测线长度达53021线公里，测线间距为400米，地形离地高度为60米。
