GSNSW Exploration NSW Area I Albury 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 0.00049 degrees (approximately 50m) and shows uranium element concentration of the NSW DMR, Discovery 2000, 1994-95, AREA I, Albury in units of parts per million (or ppm). The data used to produce this grid was acquired in 1996 by the NSW Government, and consisted of 35041 line-kilometres of data at 250m line spacing and 60m terrain clearance.

放射性测量法（radiometric method，又称伽马能谱法）通过检测地球表面附近的伽马射线自然变化，表征钾（K）、铀（U）与钍（Th）的天然放射性衰变所产生的辐射响应。所采集的数据将通过标准化流程进行处理，以确保所记录的辐射响应仅源于地下岩石的放射性衰变。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查，以确保GA发布的最终数据符合使用要求。
本放射性铀元素网格的像元大小为0.00049度（约合50米），展示了新南威尔士州矿产资源部（NSW DMR）1994-1995年"Discovery 2000"项目第一区域奥尔伯里（Albury）的铀元素浓度，单位为百万分之一（ppm）。
本网格所用数据由新南威尔士州政府于1996年采集，总测线长度达35041线公里，测线间距为250米，飞行离地高度为60米。
