Full description

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 thorium grid has a cell size of 0.001 degrees (approximately 109m) and shows thorium element concentration of the Medusa Banks, Port Keats, WA, 1994 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1994 by the WA Government, and consisted of 68378 line-kilometres of data at 500m line spacing and 100m terrain clearance.
