Evaluation of non-ionizing radiation emitted by FM broadcasting and free-to-air TV systems in the municipality of El Crucero, Managua

The aim of this work is to provide an evaluation guide for the Nicaraguan telecommunications regulator Instituto Nicaraguense de Telecomunicaciones y Correos TELCOR to assess the Non-Ionizing Radiation NIR levels emitted by FM Radio and Free-To-Air TV broadcasting systems installed in the municipality of El Crucero, an empoverished municipality where 44 FM Radio and TV Broadcasting operators simultaneously transmit nearby populated areas, using measurement equipment available in TELCOR's mobile monitoring units. These mobile units, each equipped with an ESMB Monitoring Receiver, Antenna ADD-190 and Software ArgusMon 4.3, were made available for this investigation, alongside the personnel of Dirección de Calidad y Monitoreo del Espectro Radioeléctrico (DCAMER-TELCOR) for NIR measurement campaigns performed in 11 selected points in El Crucero. The measurements results show that the exposition to these emissions does not exceed 1% of ICNIRP's general public exposure limits in 7 points, and 5% on the rest.
