    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 89m) and shows uranium element concentration of the GSWA Central Canning, GA Onshore Canning merge, 2007-2009 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2007 by the WA Government, and consisted of 175415 line-kilometres of data at 800m line spacing and 60m terrain clearance.

This radiometric uranium grid has a cell size of 0.00019 degrees (approximately 20m) and shows uranium element concentration of the NTGS Mount Peake-Crawford Magnetic, Radiometric and Elevation Survey, NT 2019 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2019 by the NT Government, and consisted of 136990 line-kilometres of data at 200m line spacing and 60m terrain clearance. To constrain long wavelengths in the grid, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey grid.
