Streaky Bay - dose rate grid (AWAGS)
1d095946-b16c-419d-804e-f93a8a2bb3fd
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 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 Streaky Bay - dose rate grid (AWAGS) has a cell size of 0.0004 degrees (approximately 41m) and shows the total dose rate of the Streaky Bay Airborne Magnetic Radiometric and DEM survey, SA, 2018 survey. The data used to produce this grid was acquired in 2018 by the SA Government, and consisted of 90670 line-kilometres of data at 200m line spacing and 60m terrain clearance.
