Abstract : Past experiments of this project utilizing three separate and distinct radiation facilities have determined the whole body and distribution within the body of resonant electromagnetic power absorption for both man models and laboratory rodents. The absorption of such energy is reliably determined by both the frequency of radiation and the orientation of the model or rodent in electromagnetic energy fields. For an undergrounded 1.75 m tall man, power absorption has been determined for E parallel L, using scaled-down models, for the 23 to 570 MHz band with resonant power absorption at 62-68 MHz. Power absorption for the laboratory rat has been determined for the 300-800 MHz band with resonant absorption being at 600 MHz for the E parallel L orientation. At respective resonance frequencies in the E parallel L orientation for both man and laboratory rodent, maximum power absorption is found in the neck region of the body. For a grounded 1,75 m tall man, the resonance region shifts to approximately one-half the free space resonance or 30-34 MHz. Man models or laboratory rats placed in proximity of metallic reflecting surfaces experience considerably enhanced electromagnetic energy depositions. Behavioral experiments with laboratory rats have shown that frequency of radiation and animal orientation in the fields are highly significant parameters in determining electromagnetic energy absorption and consequential disruption of behavioral performance.
