A new head exposure system for double-blinded human provocation studies, which requires EEG recording during exposure with GSM900- and UMTS-like signals, has been developed and dosimetrically evaluated. The system uses planar patch antennas fixed at 65 mm distance from the subject's head by a special headset, which provides minimum impairment of the test subject and ensures an almost constant position of the antennas with respect to the head, even in the case of head movement. The system satisfies the basic requirements of provocation studies Kuster et al (2004) and corresponds to an upgrade of the system used by the University of Zurich group (Huber et al (2000), Huber et al (2002), Huber et al (2003), Huber et al (2005)). A similar system has been employed in the recent studies of Regel et al (2007), Regel et al (2007), and Hillert et al (2008).
