This volume includes the lectures and selected posters on different aspects of biological
effects of EMF presented at the NATO ADVANCED RESEARCH WORKSHOP The mechanisms of biological
effect Extremely High Power Pulses (EHPP) (3-5 March 2005) and the UNESCO WHO IUPAB Seminar
Molecular and Cellular Mechanisms of Biological Effects of EMF (1-2 March 2005) that took place
in Yerevan Armenia. The gracious support of several international organizations made possible
to bring together 47 scientists engineers physicians and policy makers from 21 countries from
Europe North and South America Asia. The Capital of Armenia Yerevan provided an excellent
opportunity for discussions of the experimental data and theoretical models of EMF effect on
various levels starting from cell aqua bathing medium to the whole organism including the
human applying multidisciplinary approaches. The continuous increase of the number of man made
EMF sources leads to dramatic changes in the spectrum of EMF in the biosphere. During the last
two decades the public concern about potential hazard of EMF generated by power and
distribution lines as well as mobile communications and base stations have initiated serious
public concern and has triggered the attention of the WHO which reflected in the EMF project
of harmonization of standards. At the same time contemporary medicine largely uses EMF
diagnostic methods. The beneficial effects of EMF are complemented with a large scale of EMF
therapeutic modalities used in a number of countries helping millions of people.
