GSQ Charters Towers Clermont uranium grid geodetic

This GSQ Charters Towers Clermont uranium grid geodetic is an airborne-derived radiometric uranium window countrate grid for the Charters Towers-Clermont merge, 1987-1989 survey. 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 uranium (K), uranium (U) and uranium (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 GSQ Charters Towers Clermont uranium grid geodetic has a cell size of 0.00083 degrees (approximately 89m). The data are in units of counts per second (or cps). The data used to produce this grid was acquired in 1987 by the QLD Government, and consisted of 40255 line-kilometres of data at 400m line spacing and 60m terrain clearance.

本GSQ Charters Towers Clermont铀网格大地测量数据，系1987-1989年Charters Towers-Clermont合并调查中获取的机载辐射铀窗口计数率网格（airborne-derived radiometric uranium window countrate grid）。辐射测量法（又称伽马能谱法，gamma-ray spectrometric method）通过检测地表附近伽马射线的自然变化，反映钾（K）、铀（U）与钍（Th）的自然放射性衰变结果。收集的数据经标准方法处理，确保记录的响应仅源于地下岩石。处理结果生成的数据集可用于揭示地下地质结构。GA地球物理学家对处理后的数据进行质量核查，确保GA发布的最终数据具备预期适用性。

本数据的单元格大小为0.00083度（约89米），单位为每秒计数（counts per second，cps）。生成该网格的原始数据由昆士兰政府（QLD Government）于1987年采集，涵盖40255测线公里，测线间距400米，飞行离地高度60米。
