[Effect of wide-band modulated electromagnetic fields on the workers of high-frequency telephone exchanges].

Physiological examinations of 63 subjects were performed as well as clinical, functional, paraclinical, etc. examinations of 82 subjects working under the effect of wide-band modulated electromagnetic fields in HFA of telephone exchanges. Some physiological changes were found as regards the level of blood pressure and auditory threshold. Though the intensity of EMF were within the allowable limits, changes in the neuro-vegetological state, genital sphere, were found in some of the examined workers as well as in immunologic reactivity and some paraclinical indices, described to develop under electromagnetic effect, attributed to the specificity of EMF-wide-band, modulated.
