Networks of EMF Area Monitor for Distributed Human Exposure Monitoring: Assessment of Performances in Simulated Realistic Scenarios

Multi-Band Area Monitors are currently employed by national authorities and agencies to implement monitoring networks able to evaluate the exposure generated by RF-EMF sources in a given geographical area. In most of the cases the focus is the evaluation of the exposure generated by sources operating in High Frequency Bands (f > 30 MHz), but in some particular case the sources operate in Low Frequency Bands (10 kHz–30 MHz), e.g. high power transmitters for long distance communications. Depending from the different applicative scenarios present in the different nodes of the network, an Area Monitor can be equipped or not with a cabling for the connection to an external power source. Since it is well known that low frequency electric fields are very sensitive to environmental boundary conditions, represented e.g. by interconnecting conductive cablings, some experimental activities have been performed to evaluate this kind of adverse phenomena and the effectiveness of possible countermeasures. The results of this experimental activity are described in the paper.
