No influence on selected parameters of human visual perception of 1970 MHz UMTS-like exposure.

In recent years several studies regarding possible effects of radio frequency (RF) electromagnetic fields(EMFs)oncognitivebrainfunctionwerereported.Inmanyofthesestudiesonawakehumansthe working tasks were presented visually to the test subjects, e.g., on a computer screen. Therefore, the question of where in the chain of visual perception, brain processing and response a possible effect couldbeinducedseemstobeofinterest.Inthisstudy,possibleeffectsofexposuretoageneric1.97GHz UMTS-like signal on humanvisual perception were investigated in a double blinded, crossover study
