Work exposure to electromagnetic fields

Paper i proceeding, 2009

In order to investigate whether safety guidelines for workers exposure to electromagnetic fields are complied with, it is important to be able to model the field distribution. A method of determining the phase of the field, when only field amplitudes have been measured on a set of planes in the near field of an electromagnetic source, have been tested with good result, for a test case with measured magnetic flux density in front of a transformer. When the magnetic fields are known in the body of the worker the induced current density can be calculated. Induced body current calculated with an impedance method, is also presented.
