• Abstract:

   The electromagnetic spectrum of environmental energy between (1 Hz - 9,4 GHz) was measured in the region of São José dos Campos, SP, with a sensitivity of up to -170 dBm (unidade de potência) In addition to the typical environmental radiation, the main human sources polluting this environmental radiation in these places were also identified in the measurements of the electromagnetic spectra. In the range (1 Hz to 1 kHz) the average value of the electric field strength measured in this frequency range was 50 V/m, with peaks that reached up to 730 V/m at a time. Between 1 kHz to 1 MHz, the average value of the electric field of these radiations was 1 V/m, with some peaks reaching up to 12 V/m. In the frequency range (1 MHz to 9400 MHz) there are radiations with a minimum intensity of up to -90 dBm. Several peaks above this power identify the main emission sources existing in this frequency range in the region between the years 2011 to 2022. The sensors used in these measurements were the SpectranNF e SpectranHF.
