[The effect of a high-frequency electromagnetic field (2.45 GHz) on perceptual processes, psychological performance and well-being].
In a sample of 8 male subjects the effect of an ultra-highfrequency electromagnetic field (f = 2.45 GHz) with power densities of 1,000, 500 and 100 microW/cm2 was investigated. As parameters were used the perceptional threshold in a tachistoscopic perceptional test, the total time from the numbersearch-test and the sum of acute symptoms and complaints measured by a special questionnaire. At the highest field intensity on the one side increases of the total times and of the sum of complaints occurred. The differential threshold increased distinctly under 500 microW/cm2 exposure, whereas the total times and the sum of symptoms were not affected. At the lowest power density no differences between exposure and nonexposure conditions have been found. The intraindividual variability was considerable.
