QUANTITATION OF MICROWAVE RADIATION EFFECTS ON THE EYES OF RABBITS AT 2450 MHz AND 918 MHz
Arthur W. Guy, James C. Lin, Piro O. Kramar, Ashley F. Emery · 1974
Researchers measured absorbed microwave power in rabbit eyes and found peak absorption in the vitreous, with exposures of 200 and 300 mW/cm² raising eye temperatures above 41°C.
Plain English Summary
Absorbed power peaked in the vitreous body at 0.92 mW/cm² per 1 mW/cm² incident power. Eye temperatures reached plateaus after 15-20 minutes, with 100 mW/cm² staying below 41°C while 200 and 300 mW/cm² exceeded 41°C. Eighty-one rabbits were used to determine the cataractogenic threshold for 2450 MHz radiation.
Why This Matters
Absorbed power was measured by exposing tissue to a brief 540 mW/cm² pulse and calculating power density from the temperature rise. The 2450 MHz experiments were repeated under general hypothermia to test the role of temperature in cataract formation.
