This study was designed to investigate the acute effects of the electromagnetic fields (EMF) emitted by the Universal Mobile Telecommunication System (UMTS/W-CDMA) mobile phone base stations on human cognitive function and subjective symptoms. A group of 80 volunteers; 40 adolescents (15-16 year old) and 40 adults (25-40 year old) were exposed to four conditions: 1) sham, 2) a Continuous Wave (CW) at 2140MHz, 3) a signal at 2140 MHz modulated as UMTS and 4) UMTS at 2140 MHz. in a randomised, double blinded cross-over design. The duration of each exposure was 45 minutes. During exposure the subjects performed a battery of different cognitive tasks with the Trail Making test, part B as the main outcome and completed a computer based questionnaire measuring self reported subjective symptoms. The project is finished and a manuscript is submitted for publication.

Danish Front page Det Strategiske Forskningsråd varetager forskningsprogrammet for ikke-ioniserende stråling. DSF’s bestyrelse udmønter ikke selv programmidler, og bestyrelsen har derfor nedsat en programkomite for ikke-ioniserende stråling bestående af fire anerkendte forskere. Der er afsat en samlet ramme på 30 mio. kr. til programmet. 15 mio. kr. blev uddelt i 2004, og 15 mio. kr. i 2005. Oplysninger om denne forskningsindsats – bl.a. omtale af de bevilgede projekter og forskernes oplæg på de afholdte åbne møder kan ses på DSF’s website på adressen: www.mobil.forsk.dk	Experimental study of mobile phone related radio-frequency electromagnetic radiation in healthy adults and adolescents (X-Mobil). project team: Ingunn S Riddervold,¹ Gert F Pedersen,² Niels T Andersen,³ Anders D Pedersen,⁴Jørgen Bach Andersen,²Robert Zachariae,⁵ Lars Mølhave,¹ Torben Sigsgaard,¹ and Søren K Kjærgaard¹(PI) ¹Department of Environmental and Occupational Medicine, Institute of Public Health, University of Aarhus; ²Institute of Electronic Systems, Aalborg University; ³Department of Biostatistics, Institute of Public Health, University of Aarhus, ⁴Hammel Neurocentre, Aarhus University Hospital; ⁵Psychooncology Research Unit, Aarhus University Hospital.
