Popis: | Introduction. The article presents results of a study on the hygienic evaluation of the impact of levels of electromagnetic fields (EMF) from electrical equipment, communications and navigational aids on modern automated ice-breaking vessels to the electromagnetic safety of the crew. Material and methods. The instrumental measurement of EMF levels from power equipment, electronic equipment, computers, were conducted in places of a permanent and temporary stay of the crew watches in parked icebreakers in the port and during sea trials. The assessment of the levels of electromagnetic radiation from the antennas of radio relay stations (radar) was conducted using the forecasting parameters of the EMF. Results. Onboard computers, marine electrical, communications and radar transmitters do not create electromagnetic fields exceeding the RC in crew workplaces of ship premises. Levels of EMF SHF range generated by RADAR antennas on the open deck, also do not exceed RC. Electromagnetic fields exceeding the RC are registered at work communications transmitters VHF, MF/HF on the decks of the installation of antennas transmitting devices. Discussion. There is a relevant matter of the protection of the crew from the EMF generated by the antennas of modern radars. Evaluation of the EMF RADAR intensity is only possible on the basis of data on forecasting levels of the electromagnetic radiation. To protect the crew from the EMF generated by antennas means the marine radio and RADAR on open decks should implement measures to limit exposure time to install warning signs and placards. Conclusions. There is required the improvement of normative-methodical documents in the field of the protection of the crew from the EMF. You must create a measurement technique for recording the intensity of electromagnetic radiation from the radar. Research data can be used for the development of science-based sanitary-epidemiological requirements for electromagnetic safety of the crew. |
