Measurements were taken in a variety of environmental locations, mostly houses and workplaces in urban, suburban and rural areas, outdoor and indoor, in the islands of Zante and Lesvos as well as in dwellings in Attica. Emphasis of the electromagnetic field measurements was placed on mobile frequency (RF) sources, wireless technologies and DECT telephony. In different location points a total number of 208 measurements were taken in Zante island and 355 measurements in Lesvos. In Zante, measurements were performed using Antenessa and Aaronia spectrum analyzers (HF & NF) which show the exact frequency and the signal strength of the sources including RF and EMF. All possible sources of background EMR were investigated, namely in the frequency area between 9 KHz – 1.5 GHz. In Lesvos, measurements were taken with NARDA EMR-300 RF survey meter. In Lesvos, a map of the measurement points was created and analyzed by GIS software. The measurements in Attica were also taken with NARDA EMR-300 RF. On the electrical field the maximum values were below 5V/m, however increased values of up to 3 kV/m were addressed near high voltage power transmission lines. On rural areas measurements of the electric field values were approximately 3–5 times lower than those existed in urban areas. In most cases the magnetic field values were lower than 2T. In some occasions some of the measurement values up to 6T were occasionally observed.
