Abstract : The primary goal of the Symposium was to discuss how nonionizing radiation deposits thermalizing energy in biological tissues and the means by which this energy may be detected and effectively dealt with by the conscious organism. Much is known of the mechanisms by which endotherms achieve and maintain a characteristic stable internal body temperature in the face of environmental and internal thermal stresses. Nonionizing radio-frequency radiation provides a unique thermal challenge to deep as well as peripheral tissues that must be dealt with by these same mechanisms. Over the past several years, research into the biological effects of microwave exposure has advanced considerably; research emphasis has shifted from high intensity to low intensity exposure as scientists probe more and more subtle biological effects. With this shift in emphasis has come the realization that a body temperature increase in an experimental animal exposed to microwaves implies a breakdown of thermoregulatory mechanisms. On the other hand, low intensity exposures (previously dubbed non-thermal) usually initiate immediate and efficient thermoregulatory processes that ensure the constancy of the internal body temperature.
