| Popis: | 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. |
