Abstract

Rabbits and monkeys were irradiated in the near field of a cavity-backed 2450 MHz resonant slot radiator, to determine the cataractogenic threshold. Rabbits developed cataracts at incident "apparent" power densities of 180 mW/cm2 (E2/120 pi, where E=rms/electric field strength). Monkeys sustained facial burns, but no lens damage, even at incident "apparent" power densities of 500 mW/cm2. These results were substantiated by computer thermal models.

Main findings

In near-field exposure to a 2450 MHz resonant slot radiator, rabbits developed cataracts at incident apparent power densities of 180 mW/cm2. Monkeys had facial burns but no lens damage even at incident apparent power densities of 500 mW/cm2; computer thermal models were reported to substantiate these results.
