Electromagnetic Interference in the Primary Electromagnetic Laboratory

This paper describes the measurements of the electromagnetic fields performed in the Primary Electromagnetic Laboratory at the Faculty of Electrical Engineering and Computing. Because of the many instruments present in the laboratory and the vulnerability to the ambient electromagnetic fields, it was interesting to investigate if the level of exposure to microwave frequencies exceeds the international and Croatian standards. The measurements were performed in the frequency range from 75 MHz to 3 GHz. The highest fields came from the nearby base station, but still less than 0.3 V/m, which is rather low.
