[Biological effects of electromagnetic radiation of extremely high frequencies combined with physiologically active compounds].

The study of the action of the electromagnetic radiation (EMR) of low intensity (10 microW/cm2) in the range of frequencies 120-170 GHz at the test-reaction of Infusoria Paramecium caudatum was carried out. The resonant character of the effects was established. The EMR action at 156.6 and 161.3 GHz caused the increase of infusorians mobility, the action at frequencies 151.8, 155.7, 167.1 GHz caused the mobility reduction. Isolated and combined with EMR effects of nicotine (10(-4)-10(-15) mol/l) and antimicrobial drug metronidazole (10(-5), 10(-8), 10(-9) mol/l) were investigated. The radiation at the frequency 167.1 GHz was shown to reduce the effect of nicotine (10(-9) mol/l) and to enhance the effect of metronidazole (10(-9) mol/l). This phenomenon may be explained by different effects of the substances in low concentration at the water hydrogen bonds net structure.

[The influence of electromagnetic radiation of industrial frequency on Daphnia magna (Straus)]. / Vliianie élektromagnitnogo izlucheniia promyshlennoi chastoti 50 Gts na Daphnia magna (Straus).

The influence of electromagnetic radiation of industrial frequency on survival, efficiency, physiological parameters of Daphnia magna (Straus) was investigated. The electromagnetic field with intensity of a magnetic component 15 microTl and an electrical one 12 kV/m was generated. The researches were carried out in acute and chronic experiments. The experimental group was exposed to electromagnetic radiation for 8 hours daily for 30 days. As a result of the study it was revealed that the influence of electromagnetic radiation with the given parameters did not have the lethal effect on the test objects. It was found that electromagnetic radiation negatively affected Daphnia fertility. On the average, a real fertility of the Daphnia in the experimental unit was 26.32% compared to the control. The age of puberty in the experiment increased twice in comparison with the control.

[The use of geographic information technologies in the sanitary control of an environmental electromagnetic field]. / Primenenie geoinformatsionnykh tekhnologi pri sanitarnom kontrole élektromagnitnogo polia okruzhaiushchei sredy.

Multifrequency and multiple factors are the specific features of electromagnetic pollution (EMP) of cities and towns. To measure EMP presents great difficulties. Geoinformation technologies are most suitable in monitoring electromagnetic exposures. The basic potentiality of using this techniques is shown.
