These studies clearly indicate the thermoregulatory capacity of the dog to withstand exposure to high microwave fields at specific absorption rates (SAR) of 3.7 and 6.1 W/kg. It appears that adequate thermoregulation takes place at an SAR of 3.7 W/kg but only transiently at 6.1 W/kg. These values, compared with the standardized resting metabolic rate of 3.29 W/kg (0.75), provide a basis for assessing the relationship of the thermal burden and thermo-regulatory disruption by microwaves in the dog. To elucidate the thermal potential of microwave exposure, it was helpful to conduct these exposures at various ambient temperatures in which the normal body temperature remained stable, thus permitting comparison of heat production and dissipation with our without microwaves. The zone of the thermal neutrality or thermoneutral zone of vasomotor activity, 22-26.5 deg C, where body temperature is regulated by changes in vasomotor tonus, fulfilled this requirement.
