Airborne Atmospheric Electric Measurements Over a Mountain Ridge and in Radioactive Debris

Airborne measurement of atmospheric conductivity in fifteen-day-old thermonuclear debris

“…In considering past data, it was found that only 5 flights out of a total of 27 had an exchange layer extending above 5000 feet. Consequently, the maximum The variations in potential gradient for penetration of this debris are inconclusive, as they were in the flight of March 3, 1955, [Clark and Kraakevik, 1959]. Also inconclusive were the data from the Geiger counter, since neither the magnitude of its reading nor its variability differed significantly from background readings.…”
