[Sanitary specification by electromagnetic factor for radiofrequency transmitters].

The article represents structure and contents of sanitary specification by electromagnetic factor to unify radio transmitter. The authors determined requirements to calculate intensity of radio frequency electromagnetic rays and to complete calculations in sanitary specification. Complete information on calculation of radio frequency electromagnetic rays intensity should be stored in electronic carrier (diskette).

[The formation of knowledge of electromagnetic ecology among high-school students].

The article tackle the problem of ecologic education, training and development in electromagnetic safety. Electromagnetic ecology is associated with effects of electromagnetic fields, so these topics are expedient in comprehensive courses of physics, ecology, natural science, biology, geography. The authors necessitate specification of regulatory document, program, methods and means of giving such knowledge.

[Features of control of electromagnetic radiation emitted by personal computers].

Measurements of PC electromagnetic irradiation show that the main sources are PC blocks emitting the waves of certain frequencies. Use of wide-range detectors measuring field intensity in assessment of PC electromagnetic irradiation gives unreliable results. More precise measurements by selective devices are required.

[Hygienic regulation of electromagnetic radiation of 300-3000 MHz frequency range].

The article contains analysis of national standards determining maximal allowable levels of electromagnetic exposure in some developed countries. The point of specific interest is the levels in frequency range of 300 MHz-30 GHz, as this range is widely used in most apparatus for mobile communication. Different in various countries, values of the maximal allowable levels appear to be the most strict in Russia.

[Ecological aspects of electromagnetic radiation emitted by mobile stations of communication means].

Electromagnetic environment of staffers using mobile communication means is characterized by complicated field structure with prevalent magnetic load. Biologic effects of the field parameters depend to large extent on location of emitting source and exposed object, presence of reflecting articles and grounding in the neighborhood. Human body is sensitive to electromagnetic influence on the certain organs.
