Abstract
Electromagnetic field (EMF) monitoring activities provide transparent information to the public interested in the safety levels of human exposure when using various radiofrequency (RF) emitting technologies. In the present work, we investigate different methods of data processing that enable relevant knowledge extraction from the databases gathered by the Romanian EMF-fixed monitoring network. Four categories of methods are proposed and illustrated by investigating the situation of electromagnetic exposure at three locations in Bucharest, during 25 months. The conducted application methods enables field level distributions and trends, time-variability on the short- and long-term basis, cumulative influence comparison and sensing of the significant changes in the environment.
