An aerial radiac monitor system was evaluated in manned and drone aircraft to determine the feasibility of automatically correcting gamma radiation dose-rates measured at heights of 200 to 1,000 feet above terrain to the ground level 3-foot dose-rate by the introduction of a correction signal from a radar altimeter. The radiac system consisted of scintillation detector, logarithmic amplifier, summation circuit, radar altimeter, and recorder. A telemetry system relayed height-corrected information from drone aircraft to a ground station for recording. The equipment demonstrated the feasibility of per forming aerial radiological survey, with automatic height correction, in manned and drone air craft of the surveillance types now in tactical use by the Armed Forces. Information on air-to ground correlation factors was also obtained.
