"An additional interesting feature of the data concerns the relatively severe effects of fairly "low powers. At the 1700 KHz frequency, a power of only 50 mw/cm2 produced a complete cessation of bar-press responding within a ten-minute exposure period. A level of 50 mw/cm2, of course, is relatively close to the safety level of 10 mw/cm established for humans exposed to microwave fields. The fact that microwave effects are found at power levels not far above the established safety level points to the necessity for additional, careful, and comprehensive examinations of the biological effects of microwaves, with a variety of species. It is possible that not only the rat, but other species as well, may exhibit enhanced sensitivity to certain microwave frequencies."
