Using weighting filters to assess complex fields against the EU directive for worker protection

The EU Directive 2013/35/EU requires that employers perform risk assessments for workers exposure to Electromagnetic fields. The exposure limit values are expressed as the induced electric field strength in the human body. The induced electric field cannot be measured, only calculated in computer simulations. In order to facilitate assessments, the directive also gives action levels expressed in electric and magnetic field strength. The action levels have been set so that the exposure limits shall not be exceeded.
