3. Electromagnetic field measurement
In order to assess the exposure of workers at their workstations, it is necessary to quantify the fields emitted by machines. The quantities used to describe exposure to electromagnetic fields are defined in table 4 .
SAR is the average energy calculated on any part or the whole of the human body.
3.1 Measuring equipment
Portable measuring devices assess workers' exposure at their workstations, i.e. on machines that emit electromagnetic fields. The interchangeable probes are isotropic: they capture the three spatial components of the field simultaneously. The display shows the resulting value.

Means of prevention
Regulations
The "physical agents" social directive specific to electromagnetic fields (2004/40/EC) of April 29, 2004 lays down the minimum requirements for the protection of workers, i.e. any person engaged in a professional activity who may be exposed to a source of electromagnetic fields, whether or not related to their own activity. It sets out the general principles of prevention, as well as the basic restrictions and reference levels...
