[The perceptibility of a microwave field under experimental conditions]

The development of effects caused physical environmental factors on subjective images and on behaviour of exposed persons generally presupposes the perceptibility of the factors concerned via receptors. Though there are no indications regarding the existence of specific receptors for electromagnetic fields as yet, one or the other person is certain of being able to notice the presence of electromagnetic fields. The perceptibility of microwave fields and related effects on short-term subjective effects have been tested in an experimental series. We found a) significant differences in the studied effects between experimental and control situations, b) stability of effects in retests, c) increasing correct indications concerning the presence of fields after several training sessions. Subjects could be discriminated regarding the individual level of effects. Moreover female versus male subjects showed different levels of correct indications of fields. The most important symptoms related to field detection are listed.
