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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid. This GSQ Cape York Doserate Grid Geodetic has a cell size of 0.00083 degrees (approximately 91m) and shows the terrestrial dose rate of the Cape York, Qld, 2009. The data used to produce this grid was acquired in 2009 by the QLD Government, and consisted of 241190 line-kilometres of data at 400m line spacing and 80m terrain clearance.

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface.
