Individual changes in human EEG caused by 450 MHz microwave modulated at 40 and 70 Hz
Environmentalist - Tập 27 - Trang 511-517 - 2007
This study was aimed to investigate the changes in the human electroencephalographic (EEG) signal caused by modulated low-level microwaves. The 450 MHz microwave exposure modulated at 40 Hz and 70 Hz frequencies was applied to a group of 15 volunteers. The field power density at the scalp was 0.16 mW/cm2. Ten cycles of the exposure (1 min on and 1 min off) at both modulation frequencies were appli......
