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 0.00039074 degrees (approximately 40m) and shows thorium element concentration of the Cobar Magnetic and Radiometric Survey, 2021 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2021 by the NSW Government, and consisted of 53617 line-kilometres of data at 200m line spacing and 60m terrain clearance.

This radiometric potassium grid has a cell size of degrees (approximately 40m) and shows potassium element concentration of the East Tasmania Magnetic and Radiometric Survey, 2022 in units of percent (or %). The data used to produce this grid was acquired in 2022 by the TAS Government, and consisted of 57178 line-kilometres of data at 200m line spacing and 80m terrain clearance.

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This East Tasmania Magnetic and Radiometric Survey, TAS, 2022, (P5020), ground elevation geoid grid is elevation data for the East Tasmania Magnetic and Radiometric Survey, 2022. This survey was acquired under the project No. 5020 for the geological survey of TAS. The grid has a cell size of degrees (approximately 40m). This grid contains the ground elevation relative to the geoid for the East Tasmania Magnetic and Radiometric Survey, 2022. It represents the vertical distance from a location on the Earth's surface to the geoid. The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

The total dose rate is due to natural sources of radiation and is computed by adding estimates of cosmic dose at ground level to the terrestrial dose. 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 total dose rate grid. This East Tasmania Magnetic and Radiometric Survey, TAS, 2022, (P5020), dose rate - total grid has a cell size of degrees (approximately 40m) and shows the total dose rate of the East Tasmania Magnetic and Radiometric Survey, 2022 survey. The data used to produce this grid was acquired in 2022 by the TAS Government, and consisted of 57178 line-kilometres of data at 200m line spacing and 80m terrain clearance.
