The electromagnetic field from GSM mobile phones suppresses glucose metabolism in the human brain, a new study has said.
Recent PET-measurements in Turku, Finland, show that glucose metabolism is suppressed in the temporoparietal and anterior temporal areas of the hemisphere next to the antenna.
Researchers of the study, initiated by Centre for Cognitive Neuroscience (CCN) at the University of Turku, exposed thirteen young healthy males to the GSM signal for 33 minutes.
The study was methodologically unique, as it combined the expertise in brain imaging (National PET-Center and CCN), measurements and modelling of radiation (Radiation and Nuclear Safety Authority in Finland, STUK) and measurements of skin temperature (Finnish Institute of Occupational Health, TTL).
No conclusions regarding health risks could be made based on the result of the study financed by Finnish Technology Agency (Tekes) as a part of the national Wirecom (wireless communication) research program.
The results of the study have been published in the Journal of Blood Circulation and Metabolism.
