Abstract

Electromagnetic radiation, which is used by broadcasting and mobile telephone systems to transmit information, permeates the city environment. In order to properly evaluate population exposure to electromagnetic fields, knowledge of their intensity and spectral components is necessary. In this study the results of radiofrequency field monitoring carried out in Torino, a large town located in the north-west of Italy are shown: the variation of the electromagnetic field strength is evaluated as a function of the height from the ground, the location in the urban area and the frequency. separating the contributions of the different sources (broadcasting antennas and radio base stations for mobile phones). Furthermore, the contribution of the radio base stations is theoretically evaluated, adding the emissions off all installations situated in Torino and examining the field strength maps calculated, considering the orography, for different heights. The theoretical values are also compared with those measured in the frequency range of mobile telephony emissions.

Main findings

Radiofrequency field monitoring in Torino assessed how electromagnetic field strength varies with height, urban location, and frequency, separating contributions from broadcasting antennas and mobile phone base stations. A theoretical evaluation summing emissions from all installations and generating field strength maps (accounting for orography) was compared with measured values in the mobile telephony frequency range.
