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. 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 Rason Throssel combined dose rate grid geodetic has a cell size of 0.00042 degrees (approximately 44m) and shows the terrestrial dose rate of the Rason-Throssel merge, 1991-1998. The data used to produce this grid was acquired in 1991 by the WA Government, and consisted of 107758 line-kilometres of data at a line spacing between 200m and 400m, and 60m terrain clearance.

Statement: This Rason Throssel combined dose rate grid geodetic is an airborne-derived radiometric terrestrial dose rate grid for the Rason-Throssel merge, 1991-1998 survey. The survey was acquired under the project No. 1350 for the geological survey of WA. The grid has a cell size of 0.00042 degrees (approximately 44m). A total of 107758 line-kilometres of data at a line spacing between 200m and 400m, and 60m terrain clearance were acquired to produce this grid. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids.
