Electromagnetic fields on board ships. Assessment of danger for the crew, hygienic regulation, Russian
experience in protection from EMF”.
Statistics shows that no less than two thirds of accidents in the water transport take place due to false actions of thenavigators and crews of ships (human factor). This report considers the problems of hygienic assessment ofelectromagnetic fields on board ships, possible role and significance of the electromagnetic factor in ensuring thenavigation safety. The unfavorable electromagnetic situation on board ships (in premises and on open decks) is formedby the changed natural electromagnetic background and EMF radiation of technical aids. First of all, these areelectro-energetic systems, which are the sources of low frequency magnetic fields. The highest levels of magnetic fields
are registered at watch posts in the premises of the power compartment. There is a problem of irradiation of the crew byradiofrequency EMF produced by the antennas of radars and marine radio communication transmitters on the opendecks. Investigations on hygienic assessment and biological effect of modulated EMF produced by the marine
radioelectronic aids were performed in the Soviet Union. As a result of the complex studies the maximum permissible
EMF levels were developed. The sanitary-epidemiological rules and norms «Electromagnetic fields on board
navigation vehicles and at marine objects. Hygienic safety requirements» were put into effect in 2006. The Federal
special program “Development of civil marine technical aids for 2009-2016” is adopted in Russia. The section of thedocument “Marine technical aids operation safety” notes the need to lower the degree of human exposure toelectromagnetic fields”. The international standards (IMO, ISO, IES and others) determine only operational
requirements to the equipment. According to our opinion, today it is necessary to develop an International standard
establishing the unified requirements to providing electromagnetic safety of ship crews.

Quasistatic electromagnetic tomography methods and its applications
developed in the Institute for Radioengineering and Electronics(Moscow, Russia)
Some new quasistatic tomography methods have been developed for different medical applications in the Laboratory ofmathematical methods in radio physics of the Institute of Radioengineering and Electronics of RAS: Electric
impedance tomography (EIT)/ Magnetic induction tomography (MIT)/ Electric field tomography (EFT). EIT is thetechnique enabling to visualize spatial distribution of electrical impedance (or conductivity) inside the human body. The
device uses voltage measurements on the object's surface when the electric current passes through the volume, as initial
data for the image reconstruction. High accuracy initial electrical data are processed by fast and effective reconstruction
algorithms. As the measurements in electrical impedance tomography can be performed rather fast, it enables tovisualize many processes (such as heart pulsation) in real time. MIT unlike EIT doesn't requires electrical contacts withthe body and uses interaction of oscillating magnetic field with conductive media. The conductivity (and permittivity)
can be reconstructed from the measurements of perturbed field outside the objects. The EFT method exploits interactionof high-frequency electric field with inhomogeneous conductive medium without contact with the electrodes. Unlike anelectrical impedance tomography no electric current is injected into the medium from the outside.

EMF Hhygienic standardization in the Russian Federation and prospects of its harmonization withinternational
In Russia EMF hygienic standards are developed on the basis of hygienic, clinical-physiological, epidemiological andexperimental researches in view of published scientific data. The main role is played the data of experimental researches
under chronic exposure allowing to receive time-value dependences of biological effects and to establish a threshold ofharmful effects. Hygienic norms are developed for discrete frequency ranges. In Russia there are hygienic norms ofoccupational exposure for hypo-geomagnetic conditions, static electric and magnetic fields, 50 Hz electric and magnetic
field and radiofrequency EMF (from 10 kHz to 300 GHz), and for special EMF case (ultra broadband pulses).
General public hygienic standards are developed for static electric field, power frequency (50 Hz) electric and magnetic
fields and radiofrequency EMF (from 30 kHz to 300 GHz). Sanitary Rules and Norms are developed for mobile
communication systems (27-2400 MHz frequency range)
and VDT. The basic problems of international
harmonization of
EMF norms is different principles of threshold permissible levels definitionin RF and ICNIRP(as international) chronic exposure adverse effects in RF and acute exposure hazard
in international rules.

Alexander Worshevsky (ELEMCOM)EMC Standardization and activities in Russia
Federal agency of technical regulation is the national competent body in Russia. EMC law is under consideration.
Technical Committee (TC EMC) prepares national EMC standards. Specialists from different institutes andorganizations work in Technical Committee. There are many subcommittees. Russian Maritime Register of shipping set
EMC requirements for shipboard equipment. Many EMC standards have become mandatory. Standards are used toprove EMC properties of products. Basic and generic standards are based on IEC standards. Many product family andproduct standards have been renovated. The equipment of potential hazardous objects such as ships, railroad, nuclear
power plants has the highest immunity. The standards require 10 immunity tests for shipboard and 16 tests for nuclear
power plant equipment. The test level is higher then the level used in generic standard for industry environment. New
current tests in grounding wires are mandatory. Immunity test of the whole system after an installation will bedetermined. EMC test equipment are produced in Russia. There are accredited laboratories for EMC tests in accordancewith national and international EMC standards. Some laboratories have unique equipment for ligtning and high level
electromagnetic field tests.

The electromagnetic field probe for registration of ultra wideband pulses
Measurement of parameters radiated ultra wideband (UWB) pulses is of interest for many applied and scientificresearches. They include an UWB radar with extremely high spatial resolution, sounding of media with average and biglosses (georadar systems), a wireless UWB communication systems, a systems for monitoring of the radiatedelectromagnetic pulses parameters. The last are used in various researches, including at the decision of theelectromagnetic compatibility problems. The main elements of such measurements are of electromagnetic field probes.
They are intended for measurements of spatial distributions of the radiated signals. As against measuring antennas, they
have the small electric sizes that allow to carry out measurements with higher spatial resolution. The majority of suchprobe designs are developed for registration a relative narrow-band (quasicoherent) signals. Even at relatively wide ofcovering frequency range, with rare exception, it cannot be used for measurements of parameters radiated UWB pulses
having relative width of a spectrum more of an octave.
It is caused by a dispersion, that is by nonlinearity of the phase characteristic the element - converter of anelectromagnetic field in an electric signal on its output. The design of the electromagnetic pulse probe is developed andinvestigated. It has the smooth phase characteristic close to linear at frequencies of 100-2500 MHz. Thus minimizationof dispersive distortions of the nanosecond pulses is achieved. The probe is made on the three-layer
printed-circuit-board together with sections of microstrip lines. The last provide balancing a connecting line between theprobe and the recording device (a digital oscillograph). Thus attenuation of inphase interfering signal is achieved on
25-30 dB. The similar probe for registration electromagnetic UWB pulses by nanosecond duration with the field
amplitude up to 50-100 kV/m is developed. Output signals of similar devices considerably differ from time function ofan electromagnetic field. The processing algorithms of the registered signals are developed and are allowing to restore
the true form of a field in a point of an arrangement of the probe.
