Aeroradiometric Surveys of North America

Data generated by aerial sensing of radiation emanating from the earth's surface provides general estimates of the geographic distribution of Uranium, Thorium, and Potassium in surficial and bedrock units. Covers the conterminous United States, southeastern Canada, and most of Alaska, but there are gaps in northern Québec, western Canada, and north central Alaska
