ABSTRACT
The authors present research findings on the problem of technology-related electromagnetic fields as an occupational risk factor of workers health disturbances, and on the issue of prevention measures development against this adverse physical factor effects. Prospects for further research development in the field of electromagnetic safety are discussed.

Specific arrangement, character, conditions and work schedule of sailing staff provide a complex of stressors. Hygienic and psychophysiologic examinations of sailing crews under stress on various ships revealed chronic occupational stress and helped to define ways eliminating causes for that stress.

Analysis of causes for sea accidents proves importance of human factor in a system "human--environment--transport". The authors consider possibility that such physical factors as noise, vibration, direct and alternate magnetic fields harm sailing staff's functional state. A universal water transport system of hygienic control over physical factors on ships is considered expedient.

The influence of extremely low frequency magnetic field on rats behavior (working memory, learning, social activity) was examined. Rats were exposed to magnetic fields at three different conditions: exposure 1-50 Hz, 46 mT; DC 65 mTl; exposure II-50 Hz, 46 mTl; DC 14-17 mTl; Exposure III-sham. Field related changes were observed after exposure I: the increase of error rate in Y-maze performance, shorter adaptation time in instrumental performance, the decrease of aggression and sociability, enhancement of the defence reactions. Data obtained show that influence of 50-Hz magnetic field depends on the level of DC field. The combination presumably considered as resonant to Ca++ was more effective.
