Stanley 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 Stanley, WA, 1999 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1999 by the WA Government, and consisted of 24080 line-kilometres of data at 400m line spacing and 80m terrain clearance.

放射测量法，亦称伽马射线能谱法，可探测地球表面附近的伽马射线自然变化，此类伽马射线源于钾（K）、铀（U）及钍（Th）的自然放射性衰变。所采集的数据将通过标准化流程进行处理，以确保记录到的响应仅来源于地下岩石。经处理得到的数据集可通过解译，用以揭示地下地质构造。已处理的数据将由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。
本放射测量铀格网的单元尺寸为0.00083度（约88米），展示了1999年西澳大利亚州（Western Australia，WA）斯坦利地区的铀元素浓度，单位为百万分率（parts per million，简称ppm）。本格网所用数据由西澳大利亚州政府于1999年采集，数据总测线长度达24080测线公里，测线间距为400米，离地高度为80米。
