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 GSQ Walsh Red River potassium grid geodetic radiometric potassium window countrate grid has a cell size of 0.00083 degrees (approximately 90m). The data are in units of counts per second (cps). The data used to produce this grid was acquired in 1992 by the QLD Government, and consisted of 54145 line-kilometres of data at 400m line spacing and 100m terrain clearance. {"type": "Polygon", "coordinates": [[[142.9914, -18.0097], [144.2588, -18.0097], [144.2588, -15.9906], [142.9914, -15.9906], [142.9914, -18.0097]]]} 142.9914 144.2588 -18.0097 -15.9906 Australia EARTH SCIENCES Earth sciences GADDS2.0 K NCI Published_External QLD airborne digital data gamma-ray geophysical survey geophysics grid potassium rad radiometrics raster spectrometry survey 600 window countrate File available for download in various formats from the GADDS2 portal documentDigital The Geophysical Archive Data Delivery System (GADDS2) portal provides HTTP download of geophysics datasets in a number of formats.
