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 0.002 degrees (approximately 210m) and shows uranium element concentration of the Yilgarn Radiometric Grid, 2006 survey. The data used to produce this grid was acquired in UNKNOWN by the WA Government, and consisted of UNKNOWN line-kilometres of data at 400.0m line spacing and UNKNOWNm terrain clearance.
