Abstract

Along to recent rapid advances on the ship with the larger proportion of electrical and electronic equipments, expansion of the usable frequency on the ship is a global trend.

Therefore, there are hazardous concern raised on the possible health effects of Electro-magnetic fields radiated from electronic device. However, although a study and a investment for Electro-magnetic fields is continued in the terrestrial area, they are not applied to a ship.

In this paper, ships is sampling and measure up to the special power distribution zone. Subsequently appropriate tests and test procedures Korean criterion regulation propose.

Also EMF Strength measure special power distribution zone. And test procedure have the three cases. first the switchboard measured. second the generator was measured. and third the transformer was measured. The measurement process of the Korean criterion restriction level.

As a result, data in Hanbada and car ship shows the next value. the measured results were satisfied with the Korean criterion, ICNIRP criterion, United Kingdom criterion. However it was not satisfied with the Italian criterion to switchboard in Hanbada ship.

The reason is not satisfied Italian criterion, Korea criterion is short-term exposure in EMF. But the crew in special power distribution worked for six hours. Therefore Korea criterion is not applied to special power distribute zone in ship.

So criterion of EMF in special power distribution zone must be specified by comparative analysis of data obtained by the experiment more and be needed to construct infrastructure in government.
