Effect of modulated 450 MHz microwave on humanEEG at different field power densities

Abstract

The experiments on the effect of modulated microwaves on human EEG were carried out on two different groups of 14 and 7 healthy volunteers exposed to 450 MHz microwave radiation modulated at 40 and 1000 Hz frequencies. The field power densities at the scalp were 0.16 mW/cm2for the first and 0.9 mW/cm2for the second group. The EEG analysis performed for individuals showed that increase in the EEG rhythm energy in both groups was comparable: up to 40% at lower and up to 30% at higher level of the field power density. Microwave caused statistically significant changes in the EEG rhythms energy for 20% of subjects in the first and for 14% of subjects in the second group. Our results suggested that effect of microwave on EEG didn’t enlarged with increase of the applied power density.
