Abstract : A hazard to aircraft transiting high power density radio and radar beams exists unless appropriate safety measures are practiced. Susceptibilities of humans, aircraft fuel vapors, avionics and electroexplosive devices to microwave radiation indicate limits of power densities of electromagnetic radiation to which aircraft may be safely exposed. From a study of the literature and analyses conducted herein, it is concluded that aircraft not carrying electroexplosive devices may be safely exposed to average power densities of 10 milliwatts per square centimeter (10 mw/sq cm) or less. Aircraft carrying electroexplosive devices may be safely exposed, under some conditions, to power densities of 1 mw/sq cm. This report contains charts, and procedures for using them, which give distances along the antenna beam axis at which the aforementioned limits are reached. It is recommended that experiments be undertaken to verify analyses in this report and that progress of the military services on electroexplosive devices be monitored to assure the earliest possible implementation less restrictive limits.
