skin a new technology called Gas Discharge Visualizationis is being developed. Gas Discharge Visualization( GDV) generates gas discharge images of the air gap around the skin in response to a train of triangular
electrical pulses( 0.1 second duration, 1000 Hz, 3kV and 106 V / s). The electric field initiates electron-ion avalanches, which result in a gas discharge along the dielectric surface. The spatial distribution of discharge
34 channels is recorded using a charge coupled optical system, digitized using a video-blaster and mathematically analyzed for several linear and nonlinear parameters including area, fractality and entropy. GDV images of each of ten fingers were obtained from cohorts of volunteers before and after a ten-minute exposure to EM fields generated by computer monitors. The results seem to indicate that two populations exist, one of which is prone to undergo remarkable changes of skin-surface electric properties, whereas the other seems to maintain unchanged properties in the conditions of the experiment( short exposures). Overall significance was determined using statistical analysis( t-test). Topical application to the face of a cream specially prepared to shield EMF hemmed the
