Abstract [en]

The emergence of new technologies and increased use of wireless voice and data transmissions has increased the human exposure to the radiofrequency (RF) electromagnetic fields (EMFs). Effective reduction measures of these fields have become more relevant in risk management at workplaces. Not only occupational health, but also counter-espionage and low electromagnetic interference are important arguments for RF EMF mitigation. This study investigates the most commonly used mitigation materials and methods of RF EMFs. The materials investigated in this study included: a graphite based paint; a wire netting; a foil paper; a metalized fabric; a transparent conductive film and other solutions. The study undertook two kinds of measurements: 1) a semi-controlled environment was created to test the mitigation materials/methods under equal conditions, 2) measurements were conducted before and after the implementation of the intervention measures in the actual living and working environments. The results revealed great differences in various mitigation materials and methods: under semicontrolled conditions the best shielding capability was achieved by metallized fabric, followed by iron wire netting and foil paper. Iron bars produced moderate screening whereas graphite paint and metallic frame proved to have little effect.
