Work exposure to electromagnetic fields

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.
