In the present work, the changes in the exposure to electromagnetic fields due to television signals incurred by the digital switchover in Thessaloniki, Greece, are investigated. It is shown that the measured electric fields comply with ICNIRP guidelines but are higher than those in the reported literature for other countries. However, this may be attributed to the selection of measurement points. Moreover, it is shown that the median value of the power density dropped from 60 μW m−2 during analog broadcasting to 13.3 μW m−2 for digital television. This finding indicates that the digital switchover has resulted in reduced exposure for the population to radiofrequency fields in the UHF range.
