ID Number		757
Study Type		Human / Provocation
Model		900, 1800 MHz (GSM) exposure to volunteers and analysis of subjective complaints.
Details		Human volunteers (n = ~40 self reported hypersensitive, n = ~30 normal) were exposed to 900 MHz (GSM +/- DTx) RF from a panel antenna set to the left side of the head for 3 hours (5 minute break at 1.5 hours) with either sham or RF at an SAR of 1.4 W/kg (blind crossover design) and evaluated for headaches, skin irritation, sensations of heat, increases in skin temperature, levels of stress-related hormones, changes in blood pressure, heart rate, heart rate variability, sleepiness, changes in cognitive performance, and effects on EEG patterns during sleep. In studies presented at BEMS 2006 in Cancun, self-reported hypersensitive individuals expressed more symptoms in general during the testing, but with no correlation to RF exposure. At the meeting in Crete Greece (2006) and in a recent publication in Bioelectromagnetics (2007), the authors reported an increase in headaches in the non-hypersensitive group (OR = 2.5; 95% CI 1.2-5.5) but not in the hypersensitive group (OR = 0.24; 95% CI 0.09-0.68).
