For the purposes of this Directive, the following definitions shall apply:

1. (a)

   "electromagnetic fields": static magnetic and time-varying electric, magnetic and electromagnetic fields with frequencies up to 300 GHz;

2. (b)

   "exposure limit values": limits on exposure to electromagnetic fields which are based directly on established health effects and biological considerations. Compliance with these limits will ensure that workers exposed to electromagnetic fields are protected against all known adverse health effects;

3. (c)

   "action values": the magnitude of directly measurable parameters, provided in terms of electric field strength (E), magnetic field strength (H), magnetic flux density (B) and power density (S), at which one or more of the specified measures in this Directive must be undertaken. Compliance with these values will ensure compliance with the relevant exposure limit values.
