Study Type		Human / Provocation
Model		900 MHz (GSM) exposure to human volunteers and analysis of blood flow in the brain
Details		Human volunteers (n = 11) were exposed to 900 MHz (GSM) RF for 2 separate sessions of 40 minutes each using a mobile phone hooked up to the local network and placed to the left side of the head. No SAR was measured or modeled, although the manufacturers max reported SAR was 0.5 W/kg. Before and after each exposure session, the subjects were questioned regarding subjective symptoms (tension, difficulty concentrating, tingling of skin, dizziness, redness of ears, sensations of warmth on the skin, pain, and headache). The authors evaluated blood oxygenation in the frontal cortex of the brain using functional near-infrared spectroscopy (fNIRS). None of the subjective measures were reported to change with exposure, although the authors report a slight and statistically significant linear increase in deoxygenated hemegobin in the frontal cortex with exposure. Oxygenated hemegobin and total hemeglobin also decreased with exposure, but the change was not statistically significant.
