Gamma-ray spectrometer profiles, Ottawa, Ontario to Yellowknife, Northwest Territories. This item comprises data derived from work carried out in July and August 1969. The data are presently in computer-plotted form showing total, potassium, uranium and thorium count rates, and uranium/thorium ratios plotted against distance with fiducial and mileage marks. The item is made up of 39 profiles (scale approx. 1:1,000,000) an index map and the flight lines shown on ten 1:1,000,000 sheets. Data were obtained using six 9x4 inch Nal (Tl) detector crystals at a mean terrain clearance of 500 feet. The results are corrected for variations in terrain clearance, atmospheric background radiation and Compton scattering.
