The rapid spread of mobile telephone technology has greatly increased the number of the radio base stations (RBS) in Italy during the recent years. The analysis of the electromagnetic field levels generated by radio base stations (RBS) situated on rural-agricultural lands allows evaluating the farm workers exposure in the surrounding area. These workers are generally unaware of their exposure and the potential risks, and are not trained to take appropriate precautions. The aim of this paper is to evaluate the electromagnetic field produced by a mobile phone RBS situated on a rural area according to the Italian Regulation concerning the exposure of workers to EMF and the recent European Standard that assesses “Exposure Limit Values” (ELV) and “Action Levels” (AL) in the frequency range used by the RBS.
