Assessment of personal radio frequency electromagnetic field exposure in specific indoor workplaces and possible worst-case scenarios

The aim of this study is to examine the electromagnetic field (ranging from 80 MHz to 6 GHz) exposure level at different locations over time in Prishtina, Kosovo, and develop possible worst-case exposure scenarios. We performed personal exposure measurement for persons working in the offices of some companies which are characterized by extensive use of wireless technologies. The measurements were recorded during working hours, after working hours and during the weekends. The results showed that the total mean power density value of the working day was 0.524 mW/m2. During the weekend, for the same exposure hours as working day, the mean power density value was 0.828 mW/m2. The total mean power density value has been just 0.676 mW/m2. Due to the usage of the DECT system, the total mean power density value of the work day was approximately 37% less when compared to the weekend. Based on the results obtained from our measurement campaign, we may conclude that the mean values of the power density for office environments in Kosovo are comparable with those of several European countries.
