The increasing use of MRI equipment increases the number of medical and technical personnel at risk of exposure to EMF and workplace noise. Existing domestic and foreign and regulatory documents defining controlled indicators, permissible exposure levels, control methods need adjustments that require additional research.

The authors presented new forms of professional training for specialists in occupational medicine (network type of running educational programs, electronic education and distant training technologies, etc.), based on continuous training concept with module system and creation of competency approach.

Electromagnetic field (EMF) of power transmission, broadcasting systems, etc. are health risk factor. In case of occupational exposure EMF are purposeful risk factor; for other workers and general public EMF are enforces risk factor, and in case of different emitters (mobile phones, laptops, etc.) use EMF are voluntary risk factor.The main principle of EMF occupational exposure risks management in Russia is based in concept of EMF ‘cumulative’ effects. Hygienic norms are time dependent, comprising a principle ‘protection by time’. EMF hygienic standardisation in Russia is based on the results of hygienic, clinical-physiological, epidemiological and experimental studies (directed to long-term exposure threshold effects determination), as well as the data of peer rewied scientific publications. Hygienic norms are developed for discrete frequency ranges in account of hygienic safety factor. Today EMF occupational exposure hygienic standards include: hypo-geomagnetic conditions, static electric and magnetic fields, 50 Hz electric and magnetic field, radiofrequency EMF (from 10 kHz to 300 GHz, and special EMF case (ultra broadband pulses). Dose (time-dependence) approach allowed to specify value of EMF permissible levels depending on exposure duration. This approach in radiofrequency range is realised by introduction of ‘power exposition’ (PE) and ‘maximal permissible level’ values.The progress in EMF hygienic safety problem solving is time dependent norms for frequencies from 3 Hz up to 10 kHz development, as well as attempt of near zone EMF adequate evaluation (for >300 MHz frequency range) principles.EMF risks management is based in realisation of protection by distance and protection by protective measures and means too. There are developed new methods of overhead and cable extremely high voltage transmission lines 50 Hz magnetic field decrease as well as new regulatory documents on requirements and testing of 50 Hz electric field and radiofrequency EMF individual protective means.

Introduction. Until now, in the Russian Federation, unlike Western countries, hygienic regulations have not been developed for magnetic fields (MF) of low-frequency ranges. The aim of the study is a scientific substantiation of the threshold limit values (TLV) of magnetic fields in the range of 3 Hz - 30 kHz at workplaces. Materials and methods. A comparative analysis of domestic and foreign hygienic normative-methodical documentation regulating the TLV of magnetic fields of low-frequency ranges at workplaces is carried out. When substantiating TLV in the frequency range of 3 Hz - 30 kHz, the method of calculating the corrected value of the RMS MF strength in decadal frequency bands is used, taking into account its target values for different exposure times. Results. MF sources in the frequency range 3 Hz - 30 kHz were shown to be widely used in various areas of activity. The analysis of current domestic and foreign documents regulating the impact of MF in low-frequency bands showed the possibility of harmonizing hygienic regulations. The TLV MP in decadal frequency bands and the criteria for their hygienic assessment are scientifically substantiated. Conclusion. The studies made it possible for the first time in the Russian Federation to develop MF hygienic standards in the frequency range of 3Hz - 30 kHz at workplaces, the introduction of which into the practice of sanitary and epidemiological supervision will ensure adequate control over the electromagnetic environment and preservation of workers’ health.

Assurance of workers and population’s electromagnetic safety represents a big relevance in connection with the increasing electromagnetic pollution both of in-plant and natural environment and increase with respect thereto in risk of health loss. Implementation of the principles for protection against electromagnetic fields (EMF) can be not always realized in practice by time, distance, and application of collective and individual means of protection. The question of human being’s protection against EMF has a high relevance especially in connection with potential carcinogenicity of some ranges and modes for EMF generation. Relevance of enhancement of hygienic standards and control methods for EMF, especially taking into account determination of values not only for falling energy, but for the absorbed one, has been demonstrated. The developed modern principle for solution of the problem related to adequate assessment of EMF exposition using a combination of numerical and experimental dosimetry methods, and investigational studies on animals has been separately considered.
