[Assessment of the risk due to exposure to EMF with particular reference to the protection of sensitive subjects].

Abstract

Summary: Purpose. The work illustrates useful elements for the risk assessment for workers exposed to electromagnetic fields, also in reference to sensitive subjects such as those with active implantable medical devices (AIMD). Methods. The approach introduced by Legislative Decree 81/08 for risk assessment does not explicitly include operational criteria and specific measures for the protection of sensitive subjects. In the case of workers with DMIA, the employer may refer to relevant harmonized technical standards. Results. They are shown the results of in vitro tests performed on pacemakers following the indications of the technical reference standard and employing sources of electromagnetic fields that, due to the type of signal emitted, do not allow to exclude an a priori influence on the operation of the device. Conclusions. Workers at particular risk are generally protected if the requirements established for the population are respected. This measure may, under certain conditions, not be sufficient,making it necessary to carry out more in-depth and individual assessments. However, the cases illustrated here for AIMD showed interference phenomena only in limited experimental configurations despite the levels of the electric and magnetic fields generated by the sources exceeding the limits for the general population.
