||The number of industrial applications involving electromagnetic radiation has significantly increased in recent years. These applications are likely to expose operators to electromagnetic fields exceeding the limits laid down by European Parliament and Council Directive 2004/40/EC. A survey was carried out to identify the types of equipment emitting the most radiation, which were then classified into eight types: resistance welding, magnetization, induction heating, magnetoscopy, dielectric loss welding, electrolysis, magnetic resonance imagery and microwaves. The number of installations by type was estimated by a market survey, which specifically identified several tens of thousands of resistance welding or magnetization machines. This survey enabled the deduction that at least 100,000 operators in France are at risk of exposure to electromagnetic fields. An assessment of exposure levels for operators at their workstations was undertaken for each equipment type. Electromagnetic fields were measured at 635 workstations fitted with radiation emitting machinery. For each measurement, a severity index corresponding to the ratio of the measured value to the action-triggering value (ATV) recommended by Council Directive 2004/40/EC was calculated. The results show that, for seven equipment types out of the eight which were evaluated, 25-50% of measurements resulted in electromagnetic field values exceeding the corresponding ATV. These findings demonstrate the need for prevention. In most cases, exposure reduction is achieved by moving the workstation away from the radiation source. Technical solutions do exist for certain types of equipment, such as shielding for microwave ovens and high-frequency presses.
