Montague Is uranium grid

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 0.00167 degrees (approximately 182m) and shows uranium element concentration of the Prince Regent, Camden Sound, Montague Sound, WA, 1994 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1994 by the WA Government, and consisted of 61497 line-kilometres of data at 800m line spacing and 100m terrain clearance.

辐射测量法（或称伽马射线光谱法，radiometric/gamma-ray spectrometric method）用于测量地球表面附近探测到的伽马射线的自然变化，这些变化由钾（K）、铀（U）和钍（Th）的自然放射性衰变引起。收集的数据通过标准方法处理，以确保记录的响应仅来源于地下岩石。处理结果生成的数据集可通过解释揭示地下地质结构。GA地球物理学家对处理后的数据进行质量检查，确保GA发布的最终数据符合预期用途。

该辐射铀网格的单元格大小为0.00167度（约182米），显示了1994年西澳大利亚州（WA）摄政王地区、卡姆登湾及蒙塔古湾的铀元素浓度，单位为百万分之一（parts per million，简称ppm）。生成该网格所用的数据由西澳大利亚州政府（WA Government）于1994年采集，包含61497线公里的数据，线间距为800米，地形净空高度为100米。
