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 Evans Head (Beach Sands Project), NSW, 1975 (P424), radiometric line data were acquired in 1975 by the NSW Government, and consisted of 1286 line-kilometres of data at 400m line spacing and 100m terrain clearance.
