The aim of this study was to collect example measurements of electromagnetic field exposure via smart meters for cable-transmitted (50–100 kHz) signal emissions in a meter room in Finland. We measured different smart meters and different concentrators. The magnetic fields in various situations on the meter surface ranged from 0.1−2.2 μT. The measured values were less than 10% of the ICNIRP reference level (RL) for the public (27 μT for those frequencies). When the typical spectator distance is considered, the ratio is even smaller: less than 1% of the RL. The electric fields (EFs) were between 0.2 and 2.5 V m-1 (RL 83 V m-1 for the public). In comparing the measured EF values with the RLs, the values are less than 3%. Based on our measurements, there is no need to improve the sheltering of the meters from the public.
Key words: magnetic field / electric field / smart meter
