A novel, car based, measuring system for estimation of general public outdoor exposure to radiofrequency fields (RF) has been developed. The system enables fast, large area, isotropic spectral measurements with a bandwidth covering the frequency range of 30 MHz to 3 GHz. Measurements have shown that complete mapping of a town with 15000 inhabitants and a path length of 115 km is possible to perform within 1 day. The measured areas were chosen to represent typical rural, urban and city areas of Sweden. The data sets consist of more than 70000 measurements. All measurements were performed during the daytime. The median power density was 16 µW/m 2 in rural areas, 270 µW/m 2 in urban areas, and 2400 µW/m 2 in city areas. In urban and city areas, base stations for mobile phones were clearly the dominating sources of exposure. Bioelectromagnetics. 35:227–230, 2014. © 2013 Wiley Periodicals, Inc.
