Estudio Estadístico Comparativo sobre Emisiones No Ionizantes Emitidas por Radio Bases de Telefonía Celular y Estaciones Transmisoras de Radio y Televisión en la Ciudad de Riobamba

Abstract

It is performed a comparative statistical study on Non-Ionizing Radiation emitted by cellular and radio base stations of Radio and Television Broadcasters in the city of Riobamba, developed by the Superintencia de Telecomunicaciones – Delegación Centro, to assess the state of the signal levels NIR. In the project's development team used the frequency bands coach NARDA SRM - 3000, because it was developed specifically to monitor NIR, tri-fixing - axial antennas, omnidirectional measuring the EMF in the range of 75MHz to 3GHz also for purposes of taking action was based on Annex 3 REGLAMENTO DE PROTECCION DE EMISIONES DE RADIACION NO IONIZANTE GENERADAS POR USO DE FRECUENCIAS DEL SPECTRO RADIOELECTRICO, radio spectrum, which specifies the measures taken at different distances, always referring to the boundary between far field and near field. When the collected samples were evaluatedand tabulated they have an average value of 0.0064 W/m2 (power density) emitted by cellular telephony base stations and 0.0045 W/m2 for Radio and Television Broadcasters, compared with the limit maximum allowed, only make up 24%. In conclussion the NIR signal level in the city of Riobamba is well below the critical limit allowed. It is recommended to take into account the maximum between far field and near field; this value shows the optimum point for taking samples in the direction of the antennae or panels as the case for a proper assessment of the contribution of NIR.
