    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 0.00042 degrees (approximately 43m) and shows uranium element concentration of the South West 2 (Corrigin), WA, 2012 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2012 by the WA Government, and consisted of 115492 line-kilometres of data at 200m line spacing and 50m terrain clearance.

This Thomson Extension, Qld, 2011 (P1249), radiometric line data, AWAGS levelled were acquired in 2011 by the QLD Government, and consisted of 46530 line-kilometres of data at 400m line spacing and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.
