Description:
Abstract:
Data generated by aerial sensing of radiation emanating from the earth's surface in Alaska provides general estimates of the geographic distribution of Uranium, Thorium, and Potassium in surficial and bedrock units throughout this area.
Purpose:
The grids were re-projected and geotiff images created for distribution using internet map services.
