Electromagnetic Field Measurements In Student Microwave Laboratory

This paper presents the measurements of the electromagnetic fields present in the student microwave laboratory. Due to the high altitude and vulnerability to the ambient electromagnetic fields, it was interesting to see if the level of exposure to microwave frequencies in the laboratory exceeds the international and Croatian standards. The measurements were done in the frequency range from 75 MHz to 3 GHz. The highest fields were from the nearby base station, but still only 0.25 V/m, which is app. 0.5% of the reference level, while the measured radiation from the mobile phone showed peak value of 30 V/m during call, or app. 0.9% of the reference level
