Efectul radiațiilor electromagnetice produse de sistemele de comunicații mobile asupra organismului uman / The effect of electromagnetic radiation produced by mobile communications systems on the human body

People want to be informed about the living environment, the environmental electromagnetic field is a topic of high interest. The present thesis wishes, as related to the ICNIRP norms, to investigate the degree of exposure to the electromagnetic field with emphasis on the frequency range in which mobile telephony operates. Ambient electromagnetic field measurements were made in the vicinity of 1750 mobile phone base stations before the activation of 5G technology, repeating 122 of the measurements after the activation of 5G. The exposure coefficient was also calculated in indoor spaces where indoor mobile phone stations operate. The exposure on sites where there are several types of emission or emission-reception stations was analyzed, practically creating an exposure map for this special case of sites. More than 10 million samples of the electric field intensity measured nationally during one year by the 150 sensors installed by ANCOM in the vicinity of congested, sensitive areas or where there is an agglomeration of field sources were analyzed. The general conclusion following all the measurements made or interpreted by the author is that the level of exposure to the ambient field both inside the buildings and outside them is far below the reference levels established by law, in most cases it does not exceed a few percent of them. This conclusion is also reinforced by the bibliography related to the subject. The end of the thesis evaluates the power and energy emitted by user terminals in commercial 4G and 5G networks concluding that although mobile fixed stations are the main source of exposure in terms of population fear, the closest field source to the human body is the mobile phone, the energy received from it exceeding the energy received from the radio base stations.
