Honeysuckle Creek doserate 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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.This Honeysuckle Creek doserate grid geodetic has a cell size of 0.00021 degrees (approximately 21m) and shows the terrestrial dose rate of the SMMSP - MagSpec - Honeysuckle Creek, Vic, 2001. The data used to produce this grid was acquired in 2001 by the VIC Government, and consisted of 14795 line-kilometres of data at 100m line spacing and 60m terrain clearance.

放射测量法（或称伽马射线能谱法）可检测地球表面附近的伽马射线自然变化，此类变化源自钾（K）、铀（U）与钍（Th）的自然放射性衰变。所采集的数据将通过标准方法进行处理，以确保记录的响应仅源于地下岩石。经处理后得到的数据集可通过解译揭示地下地质构造。经处理的数据将由GA地球物理学家开展质量核查，以确保GA发布的最终数据符合使用需求。地表剂量率网格通过滤波后的钾、铀、钍网格的线性组合生成。对该网格应用低通滤波器后，即可得到滤波后的地表剂量率网格。本霍尼萨克溪大地测量剂量率网格的单元格尺寸为0.00021度（约21米），展示了2001年维多利亚州霍尼萨克溪SMMSP-MagSpec项目的地表剂量率。本网格的制作数据由维多利亚州政府于2001年采集，数据总长度达14795线公里，测线间距为100米，飞行离地高度为60米。
