Hyperthermia in Rhesus Monkeys Exposed to a Frequency (225 MHz) Near Whole-Body Resonance,
Abstract
Exposure of rhesus monkeys to 225 MHz radiation caused severe hyperthermia at power densities greater than 5 mW/sq cm (2.3 W/kg). A comparison of body temperature responses to exposure at two frequencies, 225 and 1290 MHz, indicated that the resonant frequency (225 MHz) is at least two times more effective in causing hyperthermia than the higher frequency, even after considerations of specific absorption rate are included in the analysis. It was concluded, therefore, that the effects on rhesus monkeys of exposure to a resonant frequency (225 MHz) were substantially greater than what could be predicted based upon straightforward comparisons of dosimetric information (SAR) and the effects of exposures to a much higher frequency (1290 MHz).
