ID Number		1835
Study Type		Human / Provocation
Model		900 Mhz (GSM), 2 GHz (UMTS) exposure at base station levels to humans and analysis of cognitive function (replication of TNO / Zwamborn et al. 2003 study)
Details		Volunteers (n = 15) were exposed to 900 MHz (GSM) or 2 GHz (UMTS) at either 1 W/kg (GSM and UMTS) or 0.1 W/kg (UMTS only) using a small broadband antenna placed over the left ear similar to a phone. No effects of exposure were reported on several cognitive (continuous performance test), evolked potential (VEP, AEP, AE-P300), and physiologic (EEG) tests.
Findings		No Effects
Status		Completed With Publication
Principal Investigator		University Berne, Switzerland
Funding Agency		Nat'l Res Prog, Switzerland (SNSF, NRP57)
Country		SWITZERLAND

Comments		The studies are contrary to the TNO report of increased subjective symptoms as well as that reported by Croft et al (increased EEG spectral power across several frequencies, most notably alpha bands)
