The contemporary conditions of life put the biosphere, in general, and mankind, in particular, to a strong dependence of various physical factors, including electromagnetic fields (EMF). During their phylogenetic and ontogenetic development the living organisms are exposed to various magnetic fields with Earth and space origin. The natural magnetic/electromagnetic fields are characterized with their continuous and comprehensive action throughout the evolution of life on the planet. The beginning of the XXIst century is characterized with exponentially increasing pollution of the atmosphere with various new means of communications which place the entire civilization into uncontrolled action of high frequency electromagnetic fields.
