This GSWA Lake Grace potassium grid geodetic is an airborne-derived radiometric potassium window countrate grid for the Lake Grace, WA, 1995 survey. 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 GSWA Lake Grace potassium grid geodetic radiometric potassium window countrate grid has a cell size of 0.00042 degrees (approximately 43m). The data are in units of counts per second (cps). The data used to produce this grid was acquired in 1995 by the WA Government, and consisted of 4847 line-kilometres of data at 200m line spacing and 60m terrain clearance.
