Far field measurement of electric fields in an area surrounding the GSM, and TV broadcast stations in Antalya (Turkey) is presented. A great inclination to use of mobile phones as well as FM radios and TV transmitters has brought about a proliferation of new radio base stations. Lack of public information and scientific studies carried out at limit values cause a spite against radio companies. Collected data through out Antalya City demonstrates that radio emissions are about at most 10% of limit values for GSM transmitters, while it is about 50% of limit values for TV transmitters. Results show that 164 MHz radio transmitter (∼1.1 mW/kg) produces about 60 times stronger local SAR than 1800 MHz GSM transmitter (∼0.02 mW/kg), and children are more sensitive than average‐man for the same electric field intensity, and gather more SAR values.© 2007 Wiley Periodicals, Inc.
