THE NEURAL EFFECTS OF MICROWAVE RADIATION
Abstract
The form and extent of neural effects associated with exposure to microwave radiation were studied. The possibility of non-thermal effects were also investigated. The frequency range most likely to evoke direct stimulation is found to be the 400 = 2000 m. c. s. region. Radiation experiments were conducted at th higher microwave frequency bands - the 3,000, 10,000, and 25,000 m. c. s. bands in particular. Initial experiments were with isolated nerv s and me br n s. In these e periments as well as in subsequent work with lizards and toads, refrigeration procedures are used in an attempt to isolate non-thermal effects. No non-thermal effects are observed. Further experiments with mammals provide extensive information on heating effects which seem to be predominant in the higher frequency bands. A radiom ter was developed to provide a remote passive measurement of i u temperature. A response to heating by radiation is observed with the peripheral nervous system. Variations in the response are found with variations in the type of experimental animal. The response is nociceptive and can be duplicated by conductive heating. Histological work shows that no nerve damage is involved. (Author)
