The uranium content data were digitized along contour lines from 33 maps in a series entitled "Map of Uranium (Radium) Contents of Afghanistan (Western Area)," compiled by V. N. Kirsanov and R. S. Dershimanov. The thorium content data were digitized along contour lines from 33 maps in a series entitled "Map of Thorium Contents of Afghanistan (Western Area)," compiled by V. N. Kirsanov and R. S. Dershimanov. The potassium content data were digitized along contour lines from 33 maps in a series entitled "Map of Potassium Contents of Afghanistan (Western Area)," compiled by V. N. Kirsanov and R. S. Dershimanov. The gamma-ray intensity data were digitized along contour lines from 33 maps in a series entitled "Map of Gamma-Field of Afghanistan (Western Area)," compiled by V. N. Kirsanov and R. S. Dershimanov. The survey route location data were digitized along flight-lines located on 33 maps in a series entitled "Survey Routes Location and Contours of Flight Equal Altitudes. Western Area of Afghanistan," compiled by Z. A. Alpatova, V. G. Kurnosov, and F. A. Grebneva. Purpose: Unknown.

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The digital data are Geosoft databases and grids, which were created from the original digitized radiometric data identified in this report. Data accuracies thus coincided with the original survey/data processing accuracies. The final radiometric grid interval of 400 m was chosen as representative for all grids. The data in the original grids have been processed using formulas and methods that are not usually documented but that represent industry standard practices for airborne data reduction. Logical_Consistency_Report: Standard industry practices of the time were followed in data collection and processing. Completeness_Report: Areas with no data in the radiometric grids are flagged with Geosoft dummy values. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal position of the survey aircraft used to collect data being integrated into the composite grid were determined by varying standard aircraft navigation aids. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The individual radiometric surveys that make up this data set were flown in draped mode at approximately 75-100 m above the terrain. Lineage: Process_Step: Process_Description: Unknown. Process_Date: 1976-2007 Process_Step: Process_Description: Each of the original radiometric survey maps were digitized along coutour lines. The initial radiometric grids for each survey were constructed using a minimum curvature algorithm and a grid cell size appropriate for the scale of the digitized map. The digitized radiometric data for all surveys were then assembled and regridded to the final grid cell size of 400 m using a minimum curvature algorithm.
