Study Type		In Vivo
Model		1-30 MHz (AM) exposure to rabbits and analysis of EEG patterns
Details		Rabbits were exposed to between 1 - 30 MHz (AM at 60 Hz) RF at power levels of 0.5-2 kV/m. Acute exposure (2-3 hours) did not produce any detectable EEG abnormalities as long as intracranial recording electrodes, which generate strong local fields, were not used. Chronic exposure (2 hrs/day for 6 weeks) enhanced low frequency delta EEG components (0-4 Hz) and reduced high frequency beta (12-30 Hz)EEG components after 2 - 3 wks of exposure. Abnormal EEGs in exposed animals contained two major peaks in the delta and alpha bands (2 and 10 Hz), while normal EEGs contained three major peaks at 4.5, 8, and 11.5 Hz.
