Airborne measurement of snow-water equivalent using natural gamma radiation over Southern Ontario, 1972-1973 / H.S. Loijens and R.L. Grasty.: En36-502/34E-PDF
"Four gamma-ray spectrometer surveys, each 1850 km in length, were carried out using a 50,040 cm3 (3,054 in3) sodium iodide detector assembly, flown at 150 m altitude, in a Skyvan aircraft fitted with a radar altimeter and Doppler navigation system. Total radio-activity, potassium, and thorium, recorded digitally on magnetic tape were used to calculate an average snow-water equivalent for 16 km sections along each flight line. The air-borne results were compared with the measurements from 40 existing snow courses and ten experimental courses established along the flight lines"--Abstract.
