Study Type		Human / Provocation
Model		1800 MHz (GSM) exposure to humans and analysis of reaction times, cognitive function, EEG, and MEG
Details		Human volunteers (n=12) were exposed in an anechoic chamber to 1870 MHz (GSM) RF for 30 minutes with an average power output of 0.125 W and a peak output of 1 W (similar to a mobile phone operating at max power) over the subjects left ear, with an estimated SAR of 0.61 W/kg (10-gram average) or 1.41 W/kg (1-gram average). Exposure to GSM RF did not significantly effect reaction times or the ability to remember words as had been previously presented from the lab. However, small early task-specific differences in neural activity due to exposure that had been previously seen by the authors led them to hypothesise that a GSM signal might affect word encoding, possibly through some type of hippocampal interaction. In a subsequent paper, the authors used a design of length distribution of low variability periods (LDLVP) as well as energy integration of EEG results to examine subtle changes in EEG from RF exposure. Volunteers (n = 15) were exposed to 450 MHz pulse modulated at 40 Hz for 1 minute at a power density of 0.16 mW/cm2. The authors report some individuals (6) showed changes detectable using these assays.
