Time of investigation:
  • during exposure
  • after exposure

Main outcome of study (acc. to author)

EEG-data of human sampled under the influence of low frequency pulsed electromagnetic fields are altered extremely in the range of alpha-activity as well as during and after exposure for some hours. This effect is induced by field intensities lower than the given international limiting values.
