GSQ Munduberra Qld 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 0.00096 degrees (approximately 102m) and shows uranium element concentration of the Rockhampton 1 & 2, Monto & Munduberra, 1994-1995, Qld,AIRDATA in units of parts per million (or ppm). The data used to produce this grid was acquired in 1994 by the QLD Government, and consisted of 156236 line-kilometres of data at 400m line spacing and 80m terrain clearance.

辐射测量法（radiometric method，又称伽马射线能谱法）可探测地球表面附近的伽马射线自然变化，该变化源自钾（K）、铀（U）及钍（Th）的天然放射性衰变。所采集的数据将通过标准化流程进行处理，以确保记录的响应仅来自地下岩石的辐射信号。经处理后得到的数据集可用于解译，以揭示地下地质构造。经处理的数据将由GA地球物理学家开展质量检查，以确保GA发布的最终数据符合使用要求。本次发布的辐射测量铀元素网格的像元大小为0.00096度（约合102米），展示的是1994-1995年昆士兰州（Qld）罗克汉普顿1号与2号、蒙托与蒙杜贝拉区域的AIRDATA铀元素浓度数据，单位为百万分之一（ppm）。本网格所用数据由昆士兰州政府于1994年采集，总数据量为156236线公里，测线间距为400米，地形离地高度为80米。
