The release comprises contour maps at a scale of 1:250 000 showing total count, uranium, thorium and potassium concentrations, and U/Th, U/K and Th/K ratios and profiles also at a scale of 1: 250 000 of the 7 radioactivity parameters for each of the 38 flight lines that were flown at approximately 1.6 km (1 mile). This survey was carried out under the Canada Saskatchewan Agreement on Mineral Exploration and Development in Northern Saskatchewan during the summer of 1974.
