Abstract

Overview

This study evaluates the localized magnetic field (MF) exposure of the cashier’s hand from a magnetization device known as a deactivator for acousto-magnetic (AM) labels in an electronic article surveillance (EAS) system.

Findings

  • Numerical computations and measurements were executed to assess magnetic induction and electric field strength near the deactivator’s surface using high-resolution anatomical hand models.
  • Assessments were compared against action levels (AL) for limb exposure and exposure limit values (ELV) for health effects as per EU directive 2013/35/EU, employing advanced techniques like the new scaling technique and the weighted peak method in time domain (WPM-TD).
  • Findings suggest possible overestimations in regulatory AL, indicating potential non-conformities in safety standards in real-world conditions.

Conclusion

The magnetic field exposure from the EAS deactivator could be potentially hazardous, highlighting a significant need for revised safety protocols and further investigations to ensure comprehensive protection at workplaces.
