Evaluation of the Exposure to Electromagnetic Fields in Computer Labs of Schools
Abstract
Personal computers, apart from being ubiquitous in our everyday activity, very often have been object of study for eventual negative health consequences. During the recent years, a great number of schools in Albania are equipped with lab rooms for teaching computer skills. This has motivated us to carry out a campaign of measuring the intensity of electric and magnetic fields is such places in the schools of Gjirokastra. This paper presents the results of such a study for the evaluation of the possible hazard related to the exposure to this “electro-smog” of the students and teachers. This is done by comparing the measured values of physical quantities with the respective limits and standards recom-mended by scientists and established by European directives such as 2004/40/CE and 1999/519/CE.
