Mobile phones have been started to be in concern as an electromagnetic interference source in hospitals in Turkey as well as other countries. There are about 50 million subscribers in the country that each patient can be assumed as a mobile phone holder, and they always want to be in service. Meanwhile, hospital buildings are very huge buildings which are not allowing deep radio penetration through the holes. While weak signal coverage level allows mobile phones camping on operator, it forces mobiles to operate at its maximum power level of 2 W. While ANSI C63.18 offers safety distances (m) for medical devices for mobile phone usage, this study points out that output power (equivalently distance) cannot be a reason itself. This phenomenon has been examined by three-dimensional electromagnetic field distribution measurement through the health units. © 2011 Wiley Periodicals, Inc.

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.
