Análise da exposição humana aos níveis de RNI emitidas pelas ERBs na faixa de 2,5 Ghz localizadas em um distrito piloto em São Luís – MA

Abstract

This study has as main theme the measurement of the parameters of Non Ionizing Radiations (NIR) emitted by cellular Radio Base Stations (RBS) in the frequencies 4G band of 2,5 GHz. The analysis of these parameters as such as power density, intensity of electric field and magnetic field from the frequencies of the cellular (4G) systems. This study proposes to measure and make the assessment of those parameters mentioned above based on the analysis of the national standard (ANATEL resolution 303/2002). The use of information technology (IT) influences the measurement of the power density (S), electric field strength (E) and magnetic density (B) generated by Radio Base Stations (ERB), since they are modulated in analogue frequency waves in digital format. The analysis was conducted in a pilot district to measure the intensities of related magnitudes to compare with the limits set by normative standards, thus assessing whether the populations of surrounding communities in the ERB environments are exposed to levels above the limits permitted by national legislation whether or not.
