Abstract
Electric fields in areas of 50 Hz high voltage plants are typically found to be up to
the reference values or action levels, or may even locally exceed them. In such electrically
dominant exposure situations, demonstration of compliance with exposure limits is often only
possible based on the induced electric field strengths inside the body and comparison with the
exposure limit values. Numerical simulations of several exposure situations in the area of
such high voltage plants are therefore conducted and analysed with realistic human body
models. Additionally, the summation of induced electric fields inside the body during
simultaneous exposure to external electric and magnetic fields have been evaluated. It could
be shown that for the considered electrically dominant exposure situations the magnetic field
can be neglected as long as the magnetic induction stays below a certain threshold, which is
dependent on the actual external electric field
