ID Number		140
Study Type		Human / Provocation
Model		900 MHz (NMT, GSM, PCN) exposure to humans and analysis of EEG (while awake)
Details		Human subjects (n=19; 10 males [28-48 yr] and 9 females [32-57 yr]) were exposed for 30 minutes in the right ear to various types of cellular phones which included 4 analogue (900 MHz NMT) models and 2 digital models (900 MHz GSM and 1800 MHz PCS) with maximal output powers of 1-2 watts. The only statistically significant difference observed was in the absolute power of the delta wave EEG emission between sham exposed and exposed conditions. There was no difference in the relative power of the delta wave band, and no difference in theta, alpha, or beta bands. The authors interpret these findings as indicating no adverse effects of cell phone RF exposure, and attribute the statistically significant finding to statistical chance. This study was first reported at the 4th anual EBEA conference in Zagreb, Croatia, 1998
