The common use of radiocommunication systems and their dynamic development affects the exposure of people to the electromagnetic field emitted by devices operating in these systems. Due to the large number of users in the urban environment, there is the highest density of radiocommunication antennas and the electromagnetic field with the most complex frequency spectrum. The article presents the results of the recognition and assessment of exposure to electromagnetic field emitted by radiocommunication systems, based on the results of own research, characterizing the evolution of the parameters of this exposure over nearly twenty years in the center of Warszawa. The results of discussed investigations shown, that till 2020 in considered locations in public buildings and outdoor urban spaces, there was no exposure of workers to electromagnetic field in Warszawa at levels requiring a periodic inspection with respect to the labour law provisions. Discussed investigations did not cover the evaluation of locally stronger electromagnetic field exposure in the proximity of emitting antennas located usually at the building roofs or free-standing constructions.
