Method for monitoring the electromagnetic impacts due to high voltage overheads lines in Aosta Valley

The aim of this paper is to show the methodology used by the Environment Protection Agency (ARPA) of the Aosta Valley for evaluating the electromagnetic impact due to high voltage overhead lines which cross the region, with regards to public exposure. Simulation and inspections have been used to identify the buildings which can be characterized by electromagnetic pollution, due to their proximity to the lines. After the measurements it is definitely possible verify if limits are exceeded, evaluate the exposure level of population living near the lines and identify actions to reduce it. So far, two important branches were examined with the purpose to extend the controls to all lines in Aosta Valley.
