The authors analyzed a state of hygienic regulation of electromagnetic fields in Russian Federation and abroad, justified necessity of hygienic regulation of electric and magnetic fields in frequency range of 3 Hz - 30 kHz, specified MAL for electromagnetic fields at workplace, that match recommendations of international organizations on non-ionizing rays safety.

[Criterial parameter of hygienic regulation for exposure to rarely repeated ultrashort electromagnetic impulses].

The authors justified an estimated induced current density as a criterial parameter for hygienic regulation of exposure to rarely repeated ultrashort electromagnetic impulses of nanosecond duration in electrical discharge devices applied in scientific research. The authors defined a threshold for harmful effects of the impulse, set maximal allowable levels of exposure for the devices operators. Methodic and regulatory documents were specified and approved to provide electromagnetic safety for personnel working in impulse fields.

[Assessment of the health status and working capacity of electric charge plant operators].

High-power broadband electromagnetic pulses of nanosecond range duration have been found to adversely affect the health status and working capacity of electric charge plant operators. A system of measures to protect the workers from exposure to such pulses, which is based on the hygienic regulation of the exposure, has been implemented.

[Health state and performance of operators in electric discharge facilities--sources of electromagnetic impulses].

The authors revealed that potent broadband electromagnetic impulses in nanosecond range have negative influence on health state and performance of electric discharge facilities operators. Created system of measures protecting workers from such impulses is based on hygienic regulation of the exposure.

[Contemporary state of hygienic regulation of electromagnetic fields and prospective harmonizing with foreign standards].

The authors briefly present data on state of hygienic regulation of electromagnetic fields in Russian Federation and abroad, describe differences in criteria and approaches to regulation. Based on data analysis, the authors suggest possible harmonization of national and foreign norms and prospective research trends in assessing biologic influence and hygienic regulation of electromagnetic fields.

[Evaluation of occupational risk caused by exposure to electromagnetic rays]. / Otsenka professional'nogo riska ot vozdeistviia élektromagnitnykh izluchenii.

Transverse epidemiologic study of work conditions and health state among workers of Civil Aviation Department Running Radiotechnic and Communication Equipment revealed higher relative risk for arterial hypertension and coronary heart disease, occurrence of these diseases in younger age in individuals exposed to electromagnetic rays of ultra high frequency and high frequency ranges, when compared to occupational group matching by occupational and general characteristics excluding exposure to electromagnetic rays.

[Hygienic evaluation of electromagnetic situation and vibroacoustic factors at workplaces for radio-technological staff of civil airports]. / Gigienicheskaia otsenka élektromagnitnoi obstanovki i vibroakusticheskikh faktorov na rabochikh mestakh radiotekhnicheskogo personala aéroportov grazhdanskoi aviatsii.

The authors proved electromagnetic environment for staff servicing radiolocation, navigation and communication systems in civil airports to be very severe: electromagnetic irradiation of broad frequency spectrum, in impulse and continuous generation mode, varying in intensity and time, with low telluric conditions in shielded chambers, with equivalent noise levels more than by 15 dBA exceeding the allowable ones.

[Hygienic regulation of electromagnetic fields for the preservation of workers' health]. / Gigienicheskaia reglamentatsiia élektromagnitnykh polei kak mera obespecheniia sokhraneniia zdorov'ia rabotaiushchikh.

The article covered results of studied hygienic regulation of occupational exposure to electromagnetic fields for preservation of workers' health. Examples of examined professionals who run radar, navigation and communication means in civil airports proved adequacy of the approaches applied. The authors formulated prospective directions to further improve hygienic regulation of occupational exposure to electromagnetic fields.

[Biologic effects and hygienic regulation of electromagnetic fields caused by mobile communication devices]. / Voprosy biologicheskogo deistviia i gigienicheskogo normirovaniia élektromagnitnykh polei, sozdavaemykh sredstvami mobil'noi sviazi.

The authors present results of hygienic, physiologic and experimental studies and mathematic simulation of biologic effects. Experimental studies (by functional state of CNS and immune system, cytologic examination of rats' lens epithelium) on 450 and 900 MHz frequencies prove the intensity of 1,900 MW/cm2 to be hazardous for animals and supraliminal.

[Physical factors and stress]. / Fizicheskie faktory i stress.

Physical factors of occupational environment and surroundings (noise, vibration, non-ionizing electromagnetic radiation, microclimate, etc) frequently could be considered stressing hazards, as cause marked functional changes in cardiovascular and nervous systems, in hematologic, immune and cytochemical values. These changes demonstrate adaptation and compensation processes or disadaptation and subsequent asthenic, astheno-vegetative and hypothalamic syndromes.

[Characteristics of electromagnetic situation in Far North regions]. / Osobennosti élektromagnitnoi obstanovki v raionakh Krainego Severa.

Coming to Far North from moderate climate area, humans face completely different, specific electromagnetic surroundings. Far North is a place with higher levels of Earth magnetic field, that is due to increased number of potent radiostations, radars, electric supply lines and other electromagnetic field sources. This specific complex of electromagnetic factors can contribute significantly to unfavorable changes in health state of Far Northern residents and requires thorough studies and careful attention.

[Dosimetry in setting practical hygienic standards for radio-wave irradiation]. / Dozimetriia v praktike gigienicheskogo normirovaniia radiovolnovykh obluchenii.

In dosimetric approach to the hygienic norm setting of radio waves adequate metrological basis is required. Joint investigations, carried by physicists and hygienists helped solve the new medical and technical problems, connected with the creation of individual dosimeters and indicators, monitor the hygienic norms of superhigh frequency electromagnetic waves. The devices are small, light, with autonomic power supply and digital indication of current exposure dose. The devices are supposed to give signals (light, sound) if the individual hygienic levels of superhigh frequency electromagnetic waves are surpassed.
