Influence of the Interaction of a 900 MHz Signal with Gender on EEG Energy: Experimental Study on the Influence of 900 MHz Radiation on EEG med./bio.

Published in: Environmentalist 2005; 25 (2-4): 173-179

Aim of study (acc. to author)

To study the effects of electromagnetic fields emitted by cellular phones on human electroencephalogram during an auditory memory task.

Background/further details

19 healthy subjects (10 female, 9 male) participated.
A gender specific influence should be investigated.

Exposure setup
Exposure source
Chamber Faraday screen room
Setup The subjects sat on an anatomical chair, and a certified dipole antenna was fixed near their right ear at a constant distance.
Sham exposure A sham exposure was conducted.
Additional info The subjects attended two sessions, two weeks apart, with or without radiation in random order.

Main outcome of study (acc. to author)

Without irradiation the power spectrum of males was greater than that of females.
Under the influence of electromagnetic field the power spectrum of the males EEG was decreased while that of the females was increased.
The data show that the effect of the electromagnetic field exposure is gender dependent.
