Assessment of Potential Short-Term Effects of Intermittent UMTS Electromagnetic Fields on Blood Circulation in an Exploratory Study, Using Near-Infrared Imaging
Potential short-term effects of intermittent UMTS electromagnetic fields (UMTS-EMF) on the cerebral blood circulation were assessed by near-infrared imaging. Different UMTS-EMF signals and exposure positions were applied in an exploratory study on eight subjects. Since no significant changes were found, the UMTS-EMF signal and the exposure position with the maximum changes in the measurement variables were estimated.
