GSQ Adavale Qld 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 0.00096 degrees (approximately 102m) and shows uranium element concentration of the Adavale Qld, (Geomap 2005) GDI 1997/1998 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1998 by the QLD Government, and consisted of 174490 line-kilometres of data at 400m line spacing and 80m terrain clearance.

放射性测量法（radiometric），又称伽马能谱法，通过探测地表附近由钾（K）、铀（U）及钍（Th）的天然放射性衰变产生的伽马射线自然变异，以获取相关辐射响应数据。所采集的数据将通过标准化流程进行处理，确保记录的响应仅源自地下岩石的辐射。经处理得到的数据集可用于解译，以揭示地下地质构造。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。该放射性铀元素网格的单元格大小为0.00096度（约合102米），展示了昆士兰州（QLD）阿达维尔（Adavale）区域的铀元素浓度数据，该数据集对应《Geomap 2005》及GDI 1997/1998，单位为百万分率（ppm）。用于生成该网格的数据由昆士兰州政府于1998年采集，总计包含174490线公里的测量数据，测线间距为400米，地形离地高度为80米。
