Electromagnetic stray fields of the power supply systems of TEXTOR regarding the Council Recommendation (1999/519/EC)

The European Union adopted a Council Recommendation to limit the exposure of the general public to electromagnetic fields (EMF) (0 Hz–300 GHz), in July 1999. The new limits for EMF are much lower than in the past. As EMF from supplies and feeder lines of TEXTOR occur in places with public access the fields have to be known to be sure that protection limits are not exceeded or precautions can be taken against the exposure to the fields. Magnetic fields were measured in relevant areas. Different instruments have registered direct fields as well as alternating fields up to 30 kHz and from 27 MHz to 1 GHz. The mechanisms for the impacts of EMF and the sources of magnetic stray fields are listed. The results of the measurements are given and discussed. For areas where the limits are clearly exceeded, suggestions for measures or precautions to be taken are given. The results also show that in some areas further measurements have to be done.
