Electromagnetic field produced by a cell phone

摘要

The present different types of industrial applications and products make use of electromagnetic energy. One way to this energy, the constitutes the radio frequency (RF), in which radio waves and microwaves are used in telecommunications. The RF emissions can be studied in terms of energy, radiation or electric field; radiation is defined as the energy propagation through space in the form of waves or particles. This electromagnetic radiation can be understood as the set of electric and magnetic waves that move together through space generated by the movement of electrical charges that may take place in a metallic conductive object, such as an antenna. The effects of electromagnetic radiation are so generally imperceptibles, by the above is importance of the study of these waves because of the use and management of mobile devices that go hand in hand with time of use and the dissipated energy and avoid injuries in the health. In this work we present an analysis of the issued electromagnetic radiation from a cell phone. We did measurements with an device electric field measure PCE-EM29. From these measurements, we observe that there an important variation of the electromagnetic field, without cellular signal and with cellular signal, so this we indicate that the electromagnetic waves could damage tissue in the ear and the face region.
