Electromagnetic fields effects on biological and other objects

Cryogenic and superconductivity is not only involved in creation of static magnetic fields for physic, medicine but also for AC systems -generators, motors, transformers, power lines and finally for high frequency systems at some extent. All this applications are commonly beneficial, but electromagnetic field (EMF) exposure may sometime lead to adverse health effect. This article reviews possible adverse health effects for completeness in the whole range of 0 Hz - 300 GHz according to International EMF WHO Project, (static fields, 50 Hz power, HF systems-radio, TV, radar, mobile phone) with some levels recommendation and standards. The last chapter is devoted to nonbiological EMF effects e.g. on computers, magnetic media and medical implants.
