Robert combined 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 0.00063 degrees (approximately 66m) and shows uranium element concentration of the Robert merge, 1991-1998 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1991 by the WA Government, and consisted of 82900 line-kilometres of data at 300m line spacing and 60m terrain clearance.放射性测量法（又称伽马射线能谱法）通过探测地球表面附近的伽马射线自然变化开展测量，该变化源于钾（K）、铀（U）与钍（Th）的自然放射性衰变。所采集的数据将通过标准流程进行处理，以确保记录到的响应仅源自地下岩石。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GA地球物理学家开展质量校验，以确保GA发布的最终数据符合使用要求。该放射性铀格网的单元格大小为0.00063度（约66米），展示了1991-1998年Robert merge区域的铀元素浓度，单位为百万分比（ppm）。用于制作该格网的数据由西澳大利亚州政府（WA Government）于1991年采集，数据覆盖82900测线公里，测线间距为300米，地形离地高度为60米。
