Personal exposure to radiofrequency electromagnetic fields: University of Barcelona study

A study was conducted at the University of Barcelona (Physics Faculty) to assess the electromagnetic field strengths to which students are exposed in their day-to-day lives. We analyzed different radiofrequency sources (GSM900, GSM 1800, UMTS and Wi-Fi). Our aim was to analyze not only electric field strengths but also absorption, so we considered different scenarios and situations: both empty and full classrooms with personal devices switched on and off. Areas with Wi-Fi hotspots nearby were also analyzed. We observed a huge variation in the results, but the strengths were always below the limits set by the relevant regulations.
