Electromagnetic pollution or electrosmog

Magnetism and electricity are associated and inseparable phenomena, so that electromagnetism arises from the interaction of electrical and magnetic phenomena. Although electricity is a phenomenon in which the presence of waves –magnetic fields– and particles in the form of free electrons –electric fields– are associated, in practice there are circumstances in which we are faced with a clear phenomenon of electrical pollution produced by the intense electric fields that are released from the walls through which cables with alternating current pass or by electrical appliances that do not have a correct grounding; In other circumstances, the biggest problem is that of electromagnetic contamination and is associated with the presence of intense magnetic fields in the vicinity of voltage transformers, electric motors, electric heaters in kitchens or near high-voltage power lines and even in power cables. medium or low voltage of urban electric transport. Although the human being has evolved constantly exposed to natural electric and electromagnetic fields, since the beginning of the 20th century the intensity of environmental electricity has increased thousands of times due to the influence of artificial electromagnetic fields (EMF) generated by power lines. voltage, electrical networks, transformers, radio and telecommunications antennas, computer screens or by household appliances; both in our homes, as in schools and workplaces, altering the whole of the natural electrical and electromagnetic environment and affecting our health to a greater or lesser extent. Most of the phenomena of electrical and electromagnetic pollution in our homes appear when electric fields and electromagnetic fields are created from alternating electric currents (50 Hz in Europe and 60 Hz in America) that run through conductive cables or in the windings of transformers , electric motors and other electrical equipment or household appliances.

Generally, high-voltage lines are of more concern than that of small electrical appliances and although the fields generated by some electrical appliances may be lower than those of high-voltage lines or transformers, they are still thousands of times more intense than natural ones, although often their range of action is small and the time of use limited.

The effects of EMF on health depend mainly on the frequency of radiation, the intensity of the field, the size and the morphology of the exposed subject.
