RESUMO
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). Notion is that using software complex analyzing electromagnetic situation could resolve many problems and discrepancies in coordination of sanitary specification by State Sanitary and Epidemiologic Supervision.

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.

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.

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. Thus, it is expedient to introduce a term "spectral density of field intensity" and its maximal allowable level. In this case a frequency spectrum of PC electromagnetic irradiation is divided into 4 ranges, one of which is subjected to calculation of field intensity for each harmonic frequency, and others undergo assessment of spectral density of field intensity.
