Progress on detection of radioactivity by airborne equipment
Coincidence and anti-coincidence counting rate meters and also an air conductivity meter have been installed in a transport plane to measure gamma radiation from ground sources. Materials containing 0.01 percent uranium can be detected at 500 feet and at an airspeed of 150 miles per hour.
