GSQ Bowen Surat North 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 0.00083 degrees (approximately 88m) and shows uranium element concentration of the Bowen-Surat North, Qld, 2006 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2006 by the QLD Government, and consisted of 169983 line-kilometres of data at 400m line spacing and 80m terrain clearance.

辐射测量法（radiometric method），亦称伽马射线能谱法（gamma-ray spectrometric method），通过探测地球表面附近的伽马射线自然波动，来表征钾（K）、铀（U）与钍（Th）的自然放射性衰变所产生的伽马射线变化。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的放射性衰变。经处理后得到的数据集可用于解译，以揭示地下地质构造。GA地球物理学家会对处理后的数据开展质量检查，以确保GA发布的最终数据符合使用要求。本辐射法铀元素栅格数据的像元大小为0.00083度（约88米），展示了2006年昆士兰州北部鲍恩-苏拉特区域（Bowen-Surat North, Qld）的铀元素浓度，单位为百万分之一（ppm）。本栅格数据所用的原始数据集由昆士兰州政府（QLD Government）于2006年采集完成，总测线长度达169983线千米，测线间距为400米，飞行离地高度为80米。
