In general, the radiation means the distribution of energy through space particles or waves. Sources of radiation are very different: the sun, the radioactive decomposition, devices for induction heating, electromagnetic installations, electrical appliances, radio relay antenna devices, mobile phones, radars and similar. Electromagnetic radiation is a combination of oscillating electric and magnetic fields that spread through space. Electromagnetic energy is spreading space in the form of electromagnetic waves, which represents the expansion of interrelated and time-variable electrical and magnetic fields. Near each electrified body exists an electric field around the conductor through which flows an electric current generated magnetic field. In addition, the electric field strength is proportional to the voltage, and magnetic field strength is proportional to the amount of current flowing conductor. Based on that, mean to conclude that everywhere where there are current and voltage are electric, magnetic or electromagnetic fields. In the final work the general definition of magnetic and electromagnetic fields in order to more closely explain the occurrence of electromagnetic pollution and its impact on man. Today's modern world, unthinkable without the use of electricity. It is everywhere in the home, office, factory, theater and elsewhere. There is virtually no part of the planet to which not reach electromagnetic radiation that are more intense. Electromagnetic radiation as a result of rapid technological development today is perhaps one of the major threat to the health of mankind. Living world so people are constantly exposed to electromagnetic radiation, which means that people are moving and, generally speaking, live in a stronger or weaker electric or magnetic fields.
